Answer:
[tex]Rate = 0.13[/tex]
Step-by-step explanation:
Given
[tex]y = \sqrt[3] x[/tex]
Required
Determine the average rate of change over [2,7]
This is calculated as:
[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]
In this case:
[tex]b = 7[/tex] and [tex]a = 2[/tex]
So, we have:
[tex]Rate = \frac{f(7) - f(2)}{7-2}[/tex]
[tex]Rate = \frac{f(7) - f(2)}{5}[/tex]
From the table:
f(7) = 1.91
f(2) = 1.26
[tex]Rate = \frac{1.91 - 1.26}{5}[/tex]
[tex]Rate = \frac{0.65}{5}[/tex]
[tex]Rate = 0.13[/tex]

Back up:
First, calculate the slope(m)
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{13-5}{3-1}[/tex]
[tex]m = \frac{8}{2}[/tex]
[tex]m = 4[/tex]
Calculate the area using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y- 5 = 4(x - 1)[/tex]
[tex]y- 5 = 4x - 4[/tex]

the ratio of doors to windows is 1:5 . There are 186 doors and windows in a building . HOw many doors and windows are there?
Answers
Answer:
a. Doors = 31 doors
b. Windows =155 windows
Step-by-step explanation:
Given the following data;
Ratio D:W = 1:5 = 1 + 5 = 6
Total number of doors and windows = 186
Ratio of doors to windows = 1/6
Ratio of windows to doors = 5/6
To find the ratio of the doors;
Doors = 1/6 * 186
Doors = 186/6
Doors =31 doors
To find the ratio of windows;
Windows = 5/6 * 186
Windows = 930/6
Windows =155 windows

Step-by-step explanation:
Hope this helps :)
Answer:
Step-by-step explanation:
Let's solve your system by substitution.
32=4(n−5);−s+11=17
Rewrite equations:
32=4n−20;−s+11=17
Step: Solve 32=4n−20 for n:
32=4n−20
32+−4n=4n−20+−4n(Add -4n to both sides)
−4n+32=−20
−4n+32+−32=−20+−32(Add -32 to both sides)
−4n=−52
−4n/ −4 =/ −52/ −4
(Divide both sides by -4)
n=13
Step: Substitute 13 for n in −s+11=17:
−s+11=17
−s+11=17
−s+11+−11=17+−11(Add -11 to both sides)
−s=6
−s/ −1 = 6/ −1
(Divide both sides by -1)
s=−6
