Answer: 35
Step-by-step explanation:
The rate of change of a graph is given by :-
[tex]k=\dfrac{\text{Change in y avlues}}{\text{Change in x values}}[/tex]
For points : (1, 35) and (2, 70)
The rate of change for the relationship in the graph is given by :-
[tex]k=\dfrac{70-35}{2-1}=35[/tex]
Hence, the rate of change for the relationship represented in the graph = 35.
The rate of change of the relationship shown in the graph is 35 miles per hour.
Linear equationLinear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the y intercept.
Let y represent the elevator height after x seconds.
From the graph using points (0, 0) and (4, 140):
m = (140 - 0)/(4 - 0) = 35
The rate of change of the relationship shown in the graph is 35 miles per hour.

Answers
72 80 83 85 88 90 91 92 93 94
From the arrangement, we can see that the minimum is 72 and the maximum is 94. Next, the median is the middle number of the data. Since there are 10 data points, we take the average of the middle 2 numbers. The median is (88+90)/2 = 89.
When you talk about the quartiles, you draw divisions in your set. Q₁ is the middle data between the smallest and the median; Q₂ is the median; and Q₃ is the middle data between the largest and the median.

Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)
Answers
Final answer:
The circumference of a circle with a given area is 75.40 meters
Explanation:
To find the circumference of a circle, we can use the formula C = 2πr, where C is the circumference and r is the radius. First, we need to find the radius from the given area.
The formula for the area of a circle is [tex]A = \pi r^2[/tex]
Rearranging the formula, we get [tex]r = \sqrt{(A/\pi \p).[/tex]
Now, substitute the given area (452.16 square meters) into the formula and solve for r:
[tex]r = \sqrt{(452.16/3.1416)[/tex]
= 12.00 meters
Finally, plug the value of r into the circumference formula:
[tex]C = 2\pi (12.00)[/tex]
= 75.40 meters

Parent function of greatest integer function:
[tex]f(x)=[x][/tex]
For x = 0 to x= 1 , f(x)=0

What is the rate of change between the interval x = π and x = three pi over two?
Answers
The rate of change between x = π and x = three pi over two is 6/π.
Explanation:The rate of change between the interval x = π and x = three pi over two can be found by calculating the slope of the line connecting these two points on the graph. In this case, we can calculate the slope by finding the difference in y-values and dividing it by the difference in x-values:
Slope = (y₂ - y₁) / (x₂ - x₁) = (2 - (-1)) / (π - 3π/2) = (2 + 1) / (3π/2 - π) = 3 / (π/2) = 6 / π
Therefore, the rate of change between the interval x = π and x = three pi over two is 6/π.
The rate of change between x = π and x = three pi over two is 6/pi.
Explanation:The rate of change between the interval x = π and x = three pi over two can be found by determining the slope of the line connecting the two points on the graph corresponding to these x-values.
Using the coordinates (pi, -1) and (3 pi over 2, 2), we can calculate the slope as follows:
Slope = (change in y)/(change in x) = (2 - (-1))/(3 pi over 2 - pi) = 3/(pi/2) = 6/pi
So, the rate of change between x = π and x = three pi over two is 6/pi.

8(x-1)-2x=-(x+50)
Answers
8x-2x-x= 50+8
5x=58
x=58/5
= 11.6
The solution to the equation 8(x-1) - 2x = -(x + 50) is x = -6.
To solve the equation 8(x-1) - 2x = -(x + 50).
First, distribute the 8 to the terms inside the parentheses:
8x - 8 - 2x = -(x + 50)
Simplify the left side of the equation:
6x - 8 = -(x + 50)
Distribute the negative sign to the terms inside the parentheses:
6x - 8 = -x - 50
Isolate the x terms on one side and the constant terms on the other side:
6x + x = -50 + 8
Combine like terms:
7x = -42
Divide both sides of the equation by 7:
7x / 7 = -42 / 7
x = -6
Therefore, the solution to the equation 8(x-1) - 2x = -(x + 50) is x = -6.

The statement is,
The measure of Arc AC is 65 degree if angle ABC is equal to 78 degree.
Now,
Since, Sum of Measure of arc AC and angle ABC is equal to 360 degree.
So, In angle ABC is 78 degree.
Then, Measure of arc AC = 360 - 78

The Cool Company determines that the supply function for its basic air conditioning unit is S(p) = 40 + 0.008p^3 and that its demand function is D(p) = 200 - 0.16p^2, where p is the price. Determine the price for which the supply equals the demand.
Answers
S(p) = D(p)
40 + 0.008p³ = 200 - 0.16p²
We transpose all the terms to left side of the equation.
0.008p³ + 0.16p² - 160 = 0
Then, we factor out the given function. This can either be done through long division or synthetic division. Divide the equation by 0.008.
p³ + 20p² - 20000 = 0
One of the roots of the equation is 21.86. This is the only real root of the equation and the rest are imaginary.
Hence, the price should be approximately $21.86 before the demand and supply is breakeven.
A computer training institute has 625 students that are paying a course fee of $400. Their research shows that for every $20 reduction in the fee, they will attract another 50 students. What fee should the school charge to maximize their revenue?
$275
$380
$320
$325
Answers
If no changes are made, the school has a revenue of :
625*400$/student=250,000$
2.
Assume that the school decides to reduce n*20$.
This means that there will be an increase of 50n students.
Thus there are 625 + 50n students, each paying 400-20n dollars.
The revenue is:
(625 + 50n)*(400-20n)=12.5(50+n)*20(20-n)=250(n+50)(20-n)
3.
check the options that we have,
a fee of $380 means that n=1, thus
250(n+50)(20-n)=250(1+50)(20-1)=242,250 ($)
a fee of $320 means that n=4, thus
250(n+50)(20-n)=250(4+50)(20-4)=216,000 ($)
the other options cannot be considered since neither 400-275, nor 400-325 are multiples of 20.
Conclusion, neither of the possible choices should be applied, since they will reduce the revenue.
Answer: it’s D $325
