Colby and Danielle clean pools for extra money over the summer. Colby's income is determined by f(x) = 3x + 12, where x is the number of hours. Danielle's income is g(x) = 5x + 10. If Colby and Danielle were to combine their efforts, their income would be h(x) = f(x) + g(x). Create the new function h(x). If Colby works 4 hours and Danielle works 4 hours, and if they each get half of the money when they work together, will Colby make more money working alone or by teaming with Danielle?

Answers

Answer:

Colby makes more money by teaming with Danielle

Step-by-step explanation:

Colby's income =f(x) = 3x+12

and Danielle's income = g(x) = 5x+10

If they combine their efforts the combined income would be

h(x) = 3x+12+5x+10 = 8x +22

If shared equally between them

Colby would get 1/2(8x+22) = 4x+11  and

Danielle would get  1/2(8x+22) = 4x+11

Since given they worked each for 4 hours

Colby income = Danielle income= 4(4) +11 = 27

If not combined, then

Colby income 3(4) + 12=24 and

Danielle income= 5(4) +10 = 30

Because of combining Colby makes more money by teaming with Danielle.

The difference is 3 for 4 hours work.

Rectangle ABCD is similar to rectangle WXYZ. What is the value of AB if WX is & feet, AD is 12 feet, and WZ is 16 feet?

Answers

Answer:

Similar rectangles states that the corresponding sides are in proportion.

As per the statement:

Rectangle ABCD is similar to rectangle WXYZ.

WX = 8 feet, AD = 12 feet and WZ = 16 feet.

Since. Rectangle ABCD and rectangle WXYZ are similar

then;

their corresponding sides are in proportion:

[tex]\frac{AB}{WX}=\frac{BC}{XY}=\frac{CD}{YZ}=\frac{AD}{WZ}[/tex]

To find the value of AB:

[tex]\frac{AB}{WX}=\frac{AD}{WZ}[/tex]

Substitute the given values we have;

[tex]\frac{AB}{8}=\frac{12}{16}[/tex]

Multiply both sides by 8 we have;

[tex]AB = \frac{12}{16} \times 8 = \frac{96}{16}=6[/tex]

Therefore, the value of AB is 6 units.




Final answer:

The value of AB in the similar rectangles ABCD and WXYZ, given that WX is 8 feet, AD is 12 feet and WZ is 16 feet, is calculated as 6 feet by using the property of similar rectangles that the ratios of their corresponding sides are equal.

Explanation:

The subject in question deals with similar rectangles. Since rectangle ABCD is similar to rectangle WXYZ, the ratio of their corresponding sides will be equal. This means that the ratio of side AB to side WX should be the same as the ratio of side AD to side WZ.

Given that WX is 8 feet, AD is 12 feet and WZ is 16 feet, we can set up the proportion as AB/WX = AD/WZ. Substituting the known values into this proportion we get AB/8 = 12/16.

To find the value of AB, we can cross multiply and solve for AB to get AB = (8 * 12) / 16 = 6 feet.

1960, the U.S. per capita personal income was $2283. in 2000, it was $30,069. find an exponential function to model this data

Answers

Answer:

f(t) = 2283·(30069/2283)^(t/40) . . . . . t = years after 1960

Step-by-step explanation:

In simplest terms, the exponential function can be written from the initial value, the ratio of given values, and the time period over which that ratio was effective. The form is ...

... f(t) = (initial value) · (ratio of values)^(t/(time period))

This works for both increasing and decreasing exponentials.

_____

Using e as a base

It can be converted to an exponential with "e" as the base by taking logarithms.

ln(f(t)) = ln(2283) + (t/40)·ln(30069/2283) = ln(2283) + 0.06445011·t

Taking antilogs, this is ...

... f(t) = 2283·e^(0.06445011·t)

_____

Comment on accuracy

The final number (30,069) when including cents (30,069.00) has 7 significant digits. In order to get the function f(t) to reproduce that number to 7 significant digits, the multiplier of t in the exponential function must be accurate to 7 significant digits. (Fairly commonly, you will see it rounded to 2 or 3 significant digits. It cannot give 30069 even to 5 digits in that case.)

jason is training for a marathon bike ride. His average speed increase from 3 miles per hour to 6 miles per hour in 3 months find the rate of change in the miles per hour that jason bikes

Answers

Answer:

The rate of change is 1 mile per hour per month

Step-by-step explanation:

We are given

initial speed = 3 mph

final speed =6 mph

total number of months =3

now, we can use rate of change formula

we know that

rate of change = ( final speed - initial speed)/(total number of months)

now, we can plug values

and we get

Rate of change is

[tex]=\frac{6-3}{3}[/tex] mph per month

=1 mph per month

Jason's rate of change in biking speed is 1 mile per hour per month.

Jason is training for a marathon bike ride. His average speed increases from 3 miles per hour to 6 miles per hour in 3 months. To find the rate of change in the miles per hour that Jason bikes, we use the formula:

Rate of Change = (Final Speed - Initial Speed) / Time Period

The final speed is 6 miles per hour, the initial speed is 3 miles per hour, and the time period is 3 months. Therefore:

Rate of Change = (6 - 3) mph / 3 months

Rate of Change = 3 mph / 3 months

Rate of Change = 1 mph per month

Therefore, Jason's rate of change in biking speed is 1 mile per hour per month.

Use the equation below to answer these questions.
[tex]x+2=\sqrt{3x+10}[/tex]

1.) What is the solution to the equation?

2.) What is the extraneous solution? Why?

3.) In general, what is an extraneous solution?

Answers

1) [tex]x+2=\sqrt{3x+10}[/tex]

Square both sides to get

[tex](x+2)^2=(\sqrt{3x+10})^2\implies x^2+4x+4=3x+10\implies x^2+x-6=0[/tex]

Factorize and solve:

[tex]x^2+x-6=(x+3)(x-2)=0\implies x=-3,x=2[/tex]

2) I assume we take [tex]\sqrt x[/tex] to be defined only for [tex]x\ge0[/tex]. Under this condition, a solution would be extraneous if [tex]\sqrt{3x+10}[/tex] is undefined, which happens if [tex]3x+10<0[/tex].

If [tex]x=-3[/tex], then [tex]3x+10=-9+10=1[/tex], so it is not extraneous.

If [tex]x=2[/tex], then [tex]3x+10=6+10=16[/tex], so it is not extraneous.

So there are not extraneous solutions to this equation.

3) Lots of information on this on the web...

Final answer:

The solution for the given equation is x=2. -3 is an extraneous solution caused by the squaring operation and it doesn't satisfy the original equation. An extraneous solution is a solution that does not satisfy the original equation.

Explanation:

To find the solution of the equation x+2=√(3x+10), we first square both sides to eliminate the square root: (x+2)2=3x+10.

This simplifies down to x2 + 4x + 4=3x+10. Rearranging terms then gives us x2 + x - 6=0. The solutions of this quadratic equation are x=2 and x=-3.

However, if we substitute x=-3 back into the original equation, it does not hold true. Thus, -3 is an extraneous solution. This extraneous solution arises in this case because we applied the squaring operation, which is not a reversible process. An extraneous solution, generally, is a solution to a transformed equation that does not satisfy the original equation.

Step-by-step explanation:

Ratio is 30 : 4200

Divide both numbers by 30:-

= 1 : 140   (answer)

Final answer:

To calculate the ratio of time to words, divide the minutes by the number of words, resulting in a 30:4200 ratio. This ratio highlights the efficiency of typing, useful for productivity analysis.

Explanation:

The question involves calculating the ratio of time in minutes to the number of words typed. Elvie can type 4,200 words in 30 minutes. To find the ratio of time in minutes to the number of words, we divide the number of minutes by the number of words.


First, express both quantities in their simplest forms: 30 minutes and 4,200 words. Then, create the ratio as follows:



Time in minutes : Number of words = 30 : 4,200


For easier comparison or further calculations, the ratio can be simplified by dividing both terms by the greatest common divisor. However, in this case, presenting the ratio in its initial form already communicates the relationship clearly, showing how many words are typed in a given amount of time. The ratio can be crucial for understanding productivity and efficiency in typing or other time-bound tasks.

How do the graphs of the function differ from the graph of f(x)=1.5x^3

Answers

Answer: p(x) = steeper

               q(x) = less steep and reflection

               r(x) = reflection

Step-by-step explanation:

The parent graph is: f(x) = 1.5x³

If the absolute value of the coefficient in front of x³ is greater than 1.5, then it is steeper (the graph is stretched).If the absolute value of the coefficient in front of x³ is less than 1.5, then it is less steep (the graph is shrunk/compressed).A negative sign in front of the coefficient represents a reflection over the x-axis.

p(x):  2 > 1.5 , so it is stretched (steeper).

p(x): coefficient has a positive sign, so it is NOT a reflection


q(x):  1  < 1.5 , so it is shrunk/compressed (less steep).

q(x): coefficient has a negative sign, so it is a reflection over x-axis


r(x): 1.5 = 1.5 so it is neither a stretch or a shrink

r(x): coefficient has a negative sign, so it is a reflection over x-axis



Final answer:

The graph of the function f(x) = 1.5x^3 has a steep increase or decrease, exhibits symmetry, and passes through the origin.

Explanation:

When comparing the graphs of different functions, it's important to analyze their key characteristics. In the case of the function f(x) = 1.5x^3, the graph will be a cubic function. Here are three significant differences between the graph of f(x) = 1.5x^3 and other functions:

The graph will have a steep increase if x > 0 and a steep decrease if x < 0, due to the positive coefficient of the x^3 term.The graph will exhibit symmetry with respect to the y-axis because the power of x is odd.The graph will pass through the origin (0, 0) since there is no constant term in the function.

A recipe calls for one half cup of ingredient A for every 1 and two thirds cups of ingredient B. You use 4 cups of ingredient A. How many cups of ingredient B do you? need?

Answers

Answer:

[tex]13\frac{1}{3}[/tex] cups

Step-by-step explanation:

We are told that a recipe calls for one half cup of ingredient A for every 1 and two thirds cups of ingredient B.      

To find the number of cups of ingredient B we will use proportions.

[tex]1\frac{2}{3}=\frac{5}{3}[/tex]

[tex]\frac{\text{Number of cups of ingredient A}}{\text{Number of cups of ingredient B}} =\frac{\frac{1}{2}}{\frac{5}{3}}[/tex]

[tex]\frac{\text{Number of cups of ingredient A}}{\text{Number of cups of ingredient B}} =\frac{3}{10}[/tex]  

Now let us substitute our amount of Ingredient A =4 in our proportions.

[tex]\frac{4}{\text{Number of cups of ingredient B}} =\frac{3}{10}[/tex]

[tex]\frac{\text{Number of cups of ingredient B}}{4}=\frac{10}{3}[/tex]

Multiplying both sides of our equation by 4.

[tex]4*\frac{\text{Number of cups of ingredient B}}{4}=4*\frac{10}{3}[/tex]

[tex]\text{Number of cups of ingredient B}=\frac{40}{3}[/tex]

[tex]\text{Number of cups of ingredient B}=13\frac{1}{3}[/tex]

Therefore, we need [tex]13\frac{1}{3}[/tex] cups of ingredient B to make our recipe.

Answer:

Proportion states that the  two ratios are equal.

Given statement: A recipe calls for one half cup of ingredient A for every 1 and two thirds cups of ingredient B. You use 4 cups of ingredient A.

By using proportion definition to find ingredients B;


[tex]\frac{\frac{1}{2} }{1\frac{2}{3} } = \frac{4}{B}[/tex]

Simplify:

[tex]\frac{\frac{1}{2} }{\frac{5}{3}} = \frac{4}{B}[/tex]

By cross multiply we get;

[tex]B \cdot \frac{1}{2} = 4 \cdot \frac{5}{3}[/tex]

or

[tex]\frac{B}{2} = \frac{20}{3}[/tex]

Multiply both sides by 2 we get;

[tex]B = \frac{20}{3} \times 2 = \frac{40}{3} = 13\frac{1}{3}[/tex]

Therefore, [tex]13\frac{1}{3}[/tex] cups of ingredients B needs.

Start with a line segment connecting two points, A and B. [tex]\dfrac{DA}{BA}=3[/tex] means DA is 3 times longer than BA. Clearly, D cannot fall between A and B because that would mean DA is shorter than BA. So there are two possible locations where D can be placed on the line relative to A and B.

But with [tex]\dfrac{DB}{BA}=2[/tex], or the fact that DB is 2 times longer than BA, we can rule out one of these positions; referring to the attachment, if we place D to the left of A, then DB would be 4 times longer than BA.

Finally, [tex]\dfrac{AB}{CB}=\dfrac12[/tex], so that CB is 2 times longer than AB. Again we have two possible locations for point C (it cannot fall between A and B), but one of them forces C to occupy the same point as D. However, A, B, C, D are distinct, so C must fall to the left of A.

Now let [tex]d[/tex] be the length of AB. Then the length of CD in terms of [tex]d[/tex] is [tex]4d[/tex]. We have the coordinates of C and D, and the distance between them is [tex]\sqrt{(4-0)^2+(0-4)^2}=4\sqrt2[/tex]. So

[tex]4d=4\sqrt2\implies d=\sqrt2[/tex]

The slope of the line through C and D is

[tex]\dfrac{0-4}{4-0}=-1[/tex]

and so the equation of the line through these points is

[tex]y-4=-(x-0)\implies x+y=4[/tex]

So the coordinates of A are [tex](x,y)=(x,4-x)[/tex]. The distance between C and A is [tex]d=\sqrt2[/tex], so we have

[tex]\sqrt{(x-0)^2+(4-x-4)^2}=\sqrt{2x^2}=|x|\sqrt2=\sqrt2\implies|x|=1[/tex]

Since A falls to the right of C (in the [tex]x,y[/tex] plane, not just in the sketch), we know to take the positive value [tex]x=1[/tex]. Then the [tex]y[/tex] coordinate is [tex]y=4-1=3[/tex].

All this to say that A is the point (1, 3), so

4d= 4√2 = d= √2

The slope of the line through C and D is

[tex]\frac{0- 4}{4-0} = -1[/tex]

and so the equation of the line through these points is

y- 4 = -(x- 0) =x + y =0

So the coordinates of A are (x, y) = (x,4 -x). The distance between C and A is d= √2, so we have

[tex]\sqrt{(x-0)^2+(4- x - 4)^2} = \sqrt{2x^3} = |x| \sqrt{2} = \sqrt{2} = |x| = 1[/tex]

Since A falls to the right of C (in the x, y plane, not just in the sketch), we know to take the positive value . Then the  coordinate is .

(x-7)(x+6)

Step-by-step explanation:


The solution of the equation is -6 and 7 for factorization of the given polynomial [tex]x^{2} - x - 42[/tex].

How to factorize any given polynomial ?

Given equation :-   [tex]x^{2} - x - 42[/tex]

For finding factors of the equation, we have equate the given polynomial with zero.

∴    [tex]x^{2} - x - 42 = 0[/tex]

Factorizing the above equation,

⇒   [tex]x^{2} - 7x + 6x - 42 = 0[/tex]

⇒   [tex]x (x -7) + 6(x - 7) = 0[/tex]

⇒   [tex](x + 6)(x - 7) = 0[/tex]  

∴ Either x + 6 = 0  or  x - 7 = 0  

x1 = -6  and  x2 = 7

Where x1 and x2 are the respective factors of the given polynomial in the question.

Thus, the solution of the equation is -6 and 7 for factorization of the given polynomial [tex]x^{2} - x - 42[/tex].

Calculate s24 for the arithmetic sequence in which a13=1.9 and the common difference is d=3.7.

Answers

Answer:

The correct answer option is 42.6.

Step-by-step explanation:

We know that in a arithmetic sequence, [tex]a_{13}=1.9[/tex] and the common difference is [tex](d)=3.7[/tex].

The standard form of an arithmetic sequence is given by:

[tex]a_n=a_1+(n-1)d[/tex]

So we will substitute the given values in this formula to find the value of [tex]a_1[/tex].

[tex]a_{13}=a_1+(13-1)3.7[/tex]

[tex]1.9=a_1+(12)3.7[/tex]

[tex]1.9=a_1+44.4[/tex]

[tex]a_1=-42.5[/tex]

Now finding the 24th term"

[tex]S_{24}=a_1+(n-1)d\\\\S_{24}=-42.5+(24-1)3.7\\\\\\S_{24}=42.6[/tex].

Therefore, the 24th term of the given arithmetic sequence is 42.6.

the lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days what is the probability of randomly selecting a pregnant woman whose length of pregnancy is less than 260 days


a.0.2981


b.0.7019


c.0.8186


d.0.1814

Answers

Answer:

a. 0.2981

Step-by-step explanation:

We are told that the lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days.

Let us find z-score for 260 days.

[tex]z=\frac{x-\mu}{\sigma}[/tex], where,

[tex]x[/tex] = Sample score,

[tex]\mu[/tex] = Mean  

[tex]\sigma[/tex] = Standard deviation.

Upon substituting our given values in z-score formula we will get,

[tex]z=\frac{260-268}{15}[/tex]    

[tex]z=\frac{-8}{15}[/tex]  

[tex]z=-0.53[/tex]  

Now we will use normal distribution table to find the area that corresponds to z-score of -0.53.  

From normal distribution table we get 0.29806 as our answer. Upon rounding our answer to four decimal places we will get 0.2981 as our answer.

Therefore, probability of selecting the woman whose length of pregnancy is less than 260 days will be 0.2981 and option a is the correct choice.

Leonard wants to restrict the domain of the tangent function so that its inverse is a function. Which description best describes how he could restrict the domain?

A) Choose any interval between consecutive asymptotes.
B) Choose any interval that includes two asymptotes.
C) Choose any interval of length 2π radians.
D) Choose any interval of length π radians.

Answers

Answer:

Correct choice is A

Step-by-step explanation:

If a function has an inverse, then there is at most one x-value for each y-value.

The tangent function is periodic with period [tex]\pi.[/tex] Hence, at each value for which [tex]f(x)=\tan x[/tex] is defined, [tex]f(x+n\pi )=\tan x[/tex] for each integer n. Therefore, the function [tex]f(x)=\tan x[/tex] does not have an inverse. Since tangent is not a one-to-one function, the domain must be limited. From examining the graph of the tangent function, we see that in each interval of the form

[tex]\left((2k−1)\dfrac{\pi}{2},(2k+1)\dfrac{\pi}{2}\right)[/tex]

where k is an integer, the tangent function assumes every value in its range. Moreover, in each such interval, each y-value is achieved exactly once. Hence, we can create an invertible function by restricting the domain tangent function to one such interval. Such interval is an interval between two consecutive vertical asymptotes [tex]x=(2k−1)\dfrac{\pi}{2}[/tex] and [tex]x=(2k+1)\dfrac{\pi}{2}.[/tex]

Associative Property of MultiplicationD. Commutative Property of Addition A very handsome young lady in the store offered me a pair of blue gloves. I did not want blue, but she said they would look very pretty on a hand like mine. The remark touched me tenderly. I glanced furtively at my hand, and somehow it did seem rather a comely member. I tried a glove on my left, and blushed a little. Manifestly the size was too small for me. But I felt gratified when she said: Oh, it is just right! yet I knew it was no such thing. I tugged at it diligently, but it was discouraging work. She said: Ah! I see you are accustomed to wearing kid gloves while some gentlemen are so awkward about putting them on. It was the last compliment I had expected. I only understand about putting on the buckskin article perfectly. I made another effort, and tore the glove from the base of the thumb into the palm of the hand, and tried to hide the tear. She kept up her compliments, and I kept up my determination to deserve them or die. Ah, you have had experience! (Yes, a rip down the back of the hand) They are just right for youyour hand is very smallif they tear, you need not pay for them. (There was a rent across the middle.) I can always tell when a gentleman understands putting on kid gloves. There is a grace about it that only comes with long patience. (Meanwhile, my efforts caused the whole afterguard of the glove to fetch away, as the sailors say, and then the fabric parted across the knuckles, and nothing was left but a melancholy ruin.) I was too much flattered to make an exposure and throw the merchandise on the angels hands. I was hot, vexed, confused, yet still happy, but I hated the other boys for taking such an absorbing interest in the proceedings. I wished they were in Jericho. I felt exquisitely mean when I said cheerfully: This one does very well; it fits elegantly. I like a glove that fits. No, never mind, maam, never mind; Ill put the other on in the street. It is warm here. It was warm. It was the warmest place I ever was in. I paid the bill, and, as I passed out with a fascinating bow, I thought I detected a light in the womans eye that was gently ironical, and when I looked back from the street, and she was laughing to herself about something or other, I said to myself, with withering sarcasm: Oh, certainly; you know how to put on kid gloves, dont you?a self-complacent heel, ready to be flattered out of your senses by every petticoat that chooses to take the trouble to do it! And I tried to remember why I had entered the store in the first place, and if I shouldnt return on the morrow to complete my initial mission. Read these lines from the excerpt again: It was the last compliment I had expected. I only understand about putting on the buckskin article perfectly. I made another effort, and tore the glove from the base of the thumb into the palm of the hand, and tried to hide the tear.
