Then multiply 11/2 so that they have common denominators.

33/6 - 17/6

Then solve.

33/6 - 17/6 = 16/6

Then convert back into a mixed number.

2 4/6 or 2 2/3

The best model for the given data is likely a quadratic model because the y values increase then decrease and then increase again, a typical pattern of a quadratic model.

To determine which model best fits the given set of data: (-4,-2), (-2,1), (2,-2), (4,3), we need to examine the relationship between the x and y values. Based on the given data, there is not a consistent increase or decrease, which suggests that the best model is not linear.

Quadratic model and cubic model can also be tested as they can capture complex patterns, which makes them a good fit for data that has peaks and valleys, such as our data set.

Upon examining the data, we realize there is a pattern where the value of y increases, then decreases, then increases again which is typically of a quadratic model. Therefore, the best fit for this data set is most likely a quadratic model.

The correct answer is A.

Hope this helps.

Answer:

The answer is A.

Step-by-step explanation:

This is because it wants you to represent the answer in Slope-Intercept Form. Which is y = mx + b. B is the y intercept, which is where it starts. On a graph, the y-intercept starts at ZERO. The 3 is at the zero, so you know what the first number is. Then, you need to see the fluctuation (change) in the value of each number in the y as you increase in x. As the x increases by one, you can see that the y decreases by two. So now you know, the ROC or Rate of Change is two, which is your slope. Slope is m. So if m is two, that makes 2x.

Let B = the weight of box B

Let 2B = the weight of box A

Let 2B + 30 = the weight of box C

B + 2B + 2B + 30 = 640

5B = 610

B = 122 pounds, weight of box B

2B = 2(122) = 244 pounds, weight of box A

2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

Answer: 90b (grams)

Step-by-step explanation:

Given statement : A box weighs 90 grams.

Let b denotes the number of boxes, then the weight of b boxes will be :-

[tex]\text{Total weight of b boxes}=b\times\text{Weight of one box}\\\\\Rightarrow\ \text{Total weight of b boxes}=b\times90\\\\\Rightarrow\ \text{Total weight of b boxes}=90b[/tex]

Hence, the expression for the weight  ( in grams) of b boxes : 90b

Answer:

y = 3x + 3

Step-by-step explanation:

The graph passes through the points (-1, 0) and (0, 3).

Slope = m = Δy/Δx = (y₂ - ₁)/(x₂ - x₁) = (3 - 0)/(0 - (-1)) = 3/1 = 3.

The y-intercept (b) is at y = 3.

The equation for a straight line is

y = mx + b

Thus, the equation for your line is

y = 3x + 3

Final answer:

The expression representing the amount of rice the farmer grew this year is 1.08x, which includes the initial amount plus an additional 8% increase.

Explanation:

If a farmer grew x pounds of rice last year, and this year she grew 8% more rice than she grew last year, the number of pounds of rice she grew this year can be represented by an algebraic expression. To calculate an increase of 8%, we multiply the original amount (x) by 8% (or 0.08) and then add it to the original amount. The expression representing the total weight of rice grown this year is:

x + 0.08x

Or, combining like terms to simplify:

1.08x

This expression takes into account the original production and adds the additional 8% increase in rice production for this year.

410 is your answer, 2 subtractions signs next to eachother make a plus sign, so in the end it’s just 356+54 :)

Answer:

410

Step-by-step explanation:

This is F(n) = 3n

The X is an interger which is holding a value

The relationship between Y and X is 3n as we multiply X by 3 to get the value of Y and is proven yet so.

The rule which represent the function as shown in the table is:

                 [tex]f(n)=3n[/tex]

We are given a table as follows:

  x       2          -1         0

  y       6          -3         0

Now we are asked to find the function which represent these table of values.

a)

    [tex]f(n)=n+3[/tex]

Here x is represented by n and y by f(n)

when n=2 we must have f(n)=6

Hence, we put n=2 in the given expression and check,

[tex]f(2)=2+3=5\neq 6[/tex]

Hence, this is not a correct function.

b)

[tex]f(n)=\dfrac{1}{3}n[/tex]

Again we check for n=2

We have:

[tex]f(2)=\dfrac{1}{3}\times 2=\dfrac{2}{3}\neq 6[/tex]

Hence, it is not a correct expression.

So we are left with option: c)

c)

[tex]f(n)=3n[/tex]

By putting the value of n=2,-1 and 0

we see that the expression matches the table of values.

( since,

when n=2 we have:

[tex]f(2)=3\times 2=6[/tex]

when n= -1 we have:

[tex]f(-1)=3\times -1=-3[/tex]

and when n=0 we have:

[tex]f(0)=3\times 0=0[/tex] )

Hence, this is a correct expression.

Answer:

Francesco can achieve this amount by investing at an APR of 7.14% compounded annually , or 7% compounded every six months or 6.95% compounded quarterly

Step-by-step explanation:

This question can be solved using the concept of compounded interest

The formula for amount obtained when a principal of p was invested at a rate r compounding n times a year is:

[tex]Amt = p(1+\frac{r}{100n})^n[/tex]

Here p = 70000, amt = 75000,

So when compounded annually, n=1

[tex]Amt =p(1+\frac{r}{100n})^n\\75000=70000(1+\frac{r}{100})^1\\\frac{15}{14}=1+\frac{r}{100}\\\frac{1}{14}=\frac{r}{100}\\r = \frac{100}{14}=7.14[/tex]

For compounding every 6 months n=2

[tex]Amt =p(1+\frac{r}{100n})^n75000=70000(1+\frac{r}{200})^2\\\frac{15}{14}=(1+\frac{r}{200})^2\\\sqrt{\frac{15}{14}}=1+\frac{r}{200}\\r = 200*(\sqrt{\frac{15}{14}}-1)=7.01[/tex]

For compounding quarterly n=4

[tex]Amt =p(1+\frac{r}{100n})^n\\75000=70000(1+\frac{r}{400})^4\\\frac{15}{14}=(1+\frac{r}{400})^4\\(\frac{15}{14})^\frac{1}{4}=1+\frac{r}{400}\\r = 6.95[/tex]

Answer: An APR OF 6.98% compounded quarterly

Step-by-step explanation:

Alright, let's solve this problem! :)

First we need to subtract 5k from both sides.

3k−5k>12

Then we simplify 3k - 5k to -2k.

-2k > 12

Now we divide both sides by -2.

k < -12/2

Now we simplify 12/2 to 6.  

k < -6

Answer:

f(x)⁻¹ = 3x/(2 - x)

Step-by-step explanation:

Find the inverse of f(x) = 2x/(x+3)

The first step is to let f(x) = y

y = 2x/(x+3)

Then make x the subject of the formula

y = 2x/(x+3)

y(x + 3) = 2x

yx + 3y = 2x

yx - 2x = -3y

x(y - 2) = -3y

x = -3y/(y - 2)

∴ f(x)⁻¹ = -3x/(x - 2)

Dividing both numerator and denominator by -1;

f(x)⁻¹ = 3x/(2 - x)

Answer: 890.12 cm^3

Step-by-step explanation:

The formula for the volume of a cylinder is

[tex]V=\pi *r^2*h[/tex]

V=628.3185307 cm^3

or simply

V=628.32 cm^3

Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.

Next, the formula for the volume of a sphere is

[tex]V=\frac{4}{3} \pi *r^3[/tex]

so the volume of a hemisphere is half of that or:

[tex]V=\frac{2}{3} *\pi *r^3[/tex]

V= 261.7993878 cm^3

or simply

V=261.80 cm^3

Finally, you add both of the volumes together to get

V= 890.1179185 cm^3

or simply

V=890.12 cm^3

Answer:

option D

D. x = 5, y = 2

Step-by-step explanation:

Given in the question two equation,

Equation 1

5.3x + y = 28.5

Equation 2

4.2x + 3.1y = 27.2

rearrange equation 1 in terms of y

y = 28.5 - 5.3x

Substitute the value of y in equation 2

4.2x + 88.35 - 16.43x = 27.2

4.2x - 16.43x = 27.2 - 88.35

-12.23x = -61.15

x = 61.15/12.23

x = 5

put value of x in any of the equation

y = 28.5 - 26.5

y = 2

He would have 32 slices of butter.

The student will have 32 slices of butter if they cut 40 ounces into 1.25-ounce pieces by dividing the total amount by the size of each slice.

The student wants to know how many slices of butter they can get from 40 ounces if they are cutting it into 1.25 ounces each. To find out, they need to divide the total amount of butter by the size of each piece.

First, take the total amount of butter, which is 40 ounces.

Divide 40 ounces by the size of each slice, which is 1.25 ounces.

Calculate the division: 40 / 1.25 = 32 slices.

Therefore, the student will have 32 slices of butter if they cut 40 ounces into 1.25-ounce pieces.

He has read 46.66 %

Lets find the percentage

total pages are 300 and he has read 140

So

140/300 = 0.4666

Converting this into percentage again

We will multiply the decimal by 100

0.4666 x 100 = 46.66 %

Answer:

25 feet

Step-by-step explanation:

You can superimpose a triangle in this situation.  The height from the ground to the top of the ladder along the wall is one leg of the triangle, the distance the ladder is from the wall is the other leg, and the length of the ladder is the hypotenuse.  

Use Pythagorean theorem to solve, which is a² + b² = c² where a, and b are the legs, and c is the hypotenuse...

We have

7² + 24² = c²

   49 + 576 = c²

       625 = c²

        25 = c          

*Tecnhically the answer is ±25, but it's a length, so we disregard the negative answer.
