Answers

The answer is 0.00008325

Hope this helps!

According to given question, 12 divided by 144140 is approximately 0.000083158.

To divide 12 by 144140, simply perform the division:

12 ÷ 144140 ≈ 0.000083158

So, 12 divided by 144140 is approximately 0.000083158.

Division is a mathematical operation used to distribute a quantity or a number of items into equal parts. It involves finding out how many times one number (called the divisor) can be subtracted or taken away from another number (called the dividend) until there is nothing left or the subtraction cannot be done anymore.

The result of the division is called the quotient, and it represents the number of equal parts or groups that the dividend can be divided into by the divisor. In the division expression "a ÷ b," where "a" is the dividend and "b" is the divisor, the quotient is represented by "a/b."

For example, in the division 12 ÷ 3:

12 is the dividend (the total quantity to be divided).

3 is the divisor (the number of equal parts to divide the dividend).

The quotient is 4, as 12 can be divided into 4 equal parts of size 3.

Division is the opposite operation of multiplication. If you have two numbers, the product of their multiplication can be divided by one of the numbers to get the other number. For example, 12 × 3 = 36, and 36 ÷ 3 = 12.

Which of the following describes the non-rigid transformation in the function shown below?
y-1=-(3x+1)^2

A. The graph is shifted 3 units down.
B. The graph is stretched vertically by a factor of 3.
C. The graph is reflected across the x-axis.
D. The graph is stretched horizontally to 1/3 the original width.

Answers

Answer: The graph is stretched horizontally to 1/3 the original width

For your best understanding I will brief all the transformations that you can infere from the expression.

Take as basis the graph y = x^2

When you multiply by a negative one you make a rigid translation (reflection across the x-axys)

When you add a positive constant to the total function (which is the same that substract it from the left side) you make a rigid translation, which is shifting a number of units equal to the value of the constant up.

When you add a positive constant to the argument of the function (this is the x before squaring it), you make a rigid traslation, which is shifting the graph a number of units equal to the value of the constant left.

When you multiply this function inside the argument, the graph is stretched vertically by a factor of the number square. In this case 3^2 = 9, but it squezes the function horizontally by a factor of 1/3.

Then, my option is the fourth of the list, because the function is shrinked horizontally by a factor of 1/3 (the term strecth is being used in a wide conception: if the factor is greater than 1 it is indeed a strecht but if the factor is less than 1 the stretch is a shrinkag).


Answer:

the graph is stretched horizontally to 1/3 the original width

Step-by-step explanation:

the graph is also reflected and translated but those are rigid transformations and this is asking about the non rig transformations

A commuter must pass through five traffic lights on her way to work, and will have to stop at each one that is red. She estimates the probability model for the number of red lights she hits, as shown below.

X= # of red P(x)
0 0.05
1 0.25
2 0.35
3 0.15
4 0.15
5 0.05
a. How many red lights should she expect to hit each day?
b. What's the standard deviation?
c. Find the mean and standard deviation of the number of red lights the commuter should expect to hit on her way during a 5 day work week.

Answers

Answer:

a)  2 red lights

b) SD = 1.26

c) mean = 10, SD = 1.26

Step-by-step explanation:

a) The number of red lights she expects to hit by day can be gotten by calculating the mean of the distribution.

[tex]E(X) = \sum xP(x)[/tex]

[tex]E(X) = (0*0.05) + (1*0.25) + (2*0.35) + (3*0.15) + (4*0.15) + (5*0.15)\\E(X) = 2.25[/tex]

Since the number of lights cannot be a decimal, she expects to hit 2 lights each day

b)

Variance, [tex]V(X) = \sum(x- \mu)^{2} P(x)[/tex]

[tex]V(X) = [(0-2.25)^{2}*0.05] + [(1-2.25)^{2}*0.25] + [(2-2.25)^{2}*0.35] + [(3-2.25)^{2}*0.15] + [(4-2.25)^{2}*0.15] + [(5-2.25)^{2}*0.05][/tex]

V(X) = 0.253 + 0.391 + 0.022 + 0.084 + 0.459 + 0.378

V(X) = 1.587

Standard Deviation, [tex]SD = \sqrt{V(X)}[/tex]

[tex]SD = \sqrt{1.587}[/tex]

SD = 1.26

c) In a 5 day work week, the commuter is expected to hit an average of 5* 2 red lights, i.e. mean = number of red lights hit per day * number of days

mean = 2 * 5

mean = 10

The standard deviation will not change, SD = 1.26

6) If sec theta+tan theta = P. PT sin theta=P^2-1/P^2+1 ...?

Answers

I will use the letter x instead of theta.

Then the problem is, given sec(x) + tan(x) = P, show that

sin(x) = [P^2 - 1] / [P^2 + 1]

I am going to take a non regular path.

First, develop a little the left side of the first equation:

sec(x) + tan(x) = 1 / cos(x) +  sin(x) / cos(x) = [1 + sin(x)] / cos(x)

and that is equal to P.

Second, develop the rigth side of the second equation:

[p^2 - 1] / [p^2 + 1] =

= [ { [1 + sin(x)] / cos(x) }^2 - 1] / [ { [1 + sin(x)] / cos(x)}^2 +1 ] =

=  { [1 + sin(x)]^2 - [cos(x)]^2 } / { [1 + sin(x)]^2 + [cos(x)]^2 } =

= {1 + 2sin(x) + [sin(x)^2] - [cos(x)^2] } / {1 + 2sin(x) + [sin(x)^2] + [cos(x)^2] }

= {2sin(x) + [sin(x)]^2 + [sin(x)]^2 } / { 1 + 2 sin(x) + 1} =

= {2sin(x) + 2 [sin(x)]^2 } / {2 + 2sin(x)} = {2sin(x) ( 1 + sin(x)} / {2(1+sin(x)} =

= sin(x)

Then, working with the first equation, we have proved that [p^2 - 1] / [p^2 + 1] = sin(x), the second equation.

Okay! This took forever. BUT I got the answers!!!

You can use substitution and plug in the y value given as x+3 into xy=10.
x(x+3)=10
or
x^2+3x=10
or
x^2+3x-10=0

Then you divide the -10 into two different factors, I did 2 and -5.

x^2 is equal to xx, so now you have one x for each factor of the -10:
(x+2)(x-5)=0

This means x is either 2 or -5, and when you plug in these values to the equation y=x+3, you get:

(2,5)
and
(-5,-2)

Which are your two intersecting points!

These are the correct answers.

The simplified form of each expression is as follows:

[tex]A. \( 729 \times 33 \) simplifies to \( 3^6 \times 33 \) B. \( 3 \times 33 \) simplifies to \( 3 \times 3 \times 11 \) or \( 3^2 \times 11 \). C. \( 729 \times 29 \) simplifies to \( 3^6 \times 29 \). D. \( 3 \times 29 \) simplifies to \( 3 \times 29 \).[/tex]

To simplify these expressions, we recognize that 729 is a power of 3, specifically [tex]\( 3^6 \)[/tex], and that 33 and 29 are prime numbers. Therefore, we can express each product in terms of its prime factors.

A. For the expression [tex]\( 729 \times 33 \)[/tex] , we know that 729 is [tex]\( 3^6 \)[/tex] and 33 is a prime number. Thus, the simplified form is [tex]\( 3^6 \times 33 \)[/tex].

[tex]B. For the expression \( 3 \times 33 \), we can further break down 33 into \( 3 \times 11 \), since 33 is the product of these two prime numbers. Therefore, the simplified form is \( 3^2 \times 11 \) or \( 3 \times 3 \times 11 \).[/tex]

[tex]C. For the expression \( 729 \times 29 \), similar to expression A, 729 is \( 3^6 \) and 29 is a prime number. Hence, the simplified form is \( 3^6 \times 29 \).[/tex]

[tex]D. For the expression \( 3 \times 29 \), both 3 and 29 are prime numbers, so the expression is already in its simplest form and cannot be simplified further. Thus, the simplified form remains \( 3 \times 29 \).[/tex]In summary, the simplified forms are:

[tex]A. \( 3^6 \times 33 \) B. \( 3^2 \times 11 \) or \( 3 \times 3 \times 11 \) C. \( 3^6 \times 29 \) D. \( 3 \times 29 \)[/tex]

You have $270 in your bank account. You plan to save $80 from your paycheck each week. Which graph shows your bank account balance at the end of each week?

Answers

Y=80x+270
If you want to know how to do it just let me know

Answer:  The below graph shows the given situation.

Step-by-step explanation:

Let x represents the number of week, and y represents the total balance in the account after x weeks.

Since, initially the amount in the account = $ 270

According to the question,

Every week $80 is saved.

Thus, the total saving in x weeks = 80 × x = 80x

Since the total amount in x weeks = Initial amount + total saving.

y = 80x + 270

Which is the equation of line that shows the given situation.

x-intercept of the line is (-27/8,0)

y-intercept = (0,270)

If x=1 y = 350

If x=2 y= 430

If x=3 y =510

Thus, the points of the line are (1,350), (2,430), (3,510)

Hence we can draw the graph with help of above information.

The slope of the line passing through points J (0,0) and K (-2,8) is calculated using the slope formula and results in a slope of -4.

The question asks to calculate the slope of the line passing through points J (0,0) and K (-2,8). The slope of a line is found by the formula

slope = (y'' - y') / (x'' - x'), where (x', y') and (x'', y'') are the coordinates of two distinct points on the line. Substituting the given points into this formula gives us

slope = (8 - 0) / (-2 - 0) = 8 / -2 = -4.

What is difference between a tilt level and a dumpy level?

Answers

Final answer:

A tilt level and a dumpy level are both surveying instruments used for measuring horizontal distances and vertical elevations. The main difference is that the tilt level has a built-in compensator that eliminates the need for manual leveling, while the dumpy level requires manual leveling before each use.

Explanation:

A tilt level and a dumpy level are both surveying instruments used for measuring horizontal distances and vertical elevations. However, there are some key differences between the two.

Tilt Level: A tilt level, also known as a tilting level, is a type of level that utilizes a compensator mechanism to maintain a level plane even when the instrument itself is not level. This compensator allows for accurate measurements and eliminates the need for manually leveling the instrument each time.

Dumpy Level: A dumpy level, on the other hand, is a more traditional type of level that requires manual leveling before each use. It consists of a telescope mounted on a tripod, and the instrument is adjusted using leveling screws to ensure that it is perfectly horizontal. The dumpy level does not have a compensator like the tilt level, so the instrument needs to be leveled manually to obtain accurate measurements.

In summary, the main difference between a tilt level and a dumpy level is that the tilt level has a built-in compensator that eliminates the need for manual leveling, while the dumpy level requires manual leveling before each use.
