Answer:
$9 an hr.
Step-by-step explanation:
4 1/4 + 1 3/4 = 6
= 6hrs combined.
$54 = 54/6 = 9
=$9 an hr.
Assume the missing sequence is x
so -1536 / 384 = x / 24
so x = (24* - 1536) / 384
so x = -96
the answer is C. -96
Answer:
a. 10.2 in²/in
10.02 in²/in
b. 10 in²/in
Step-by-step explanation:
The area of a square is given by the following function:
![f(x)=x^2](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2)
The average rate of change between two points a and b is:
![r = \frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
a. For x = 5 and 5.2:
![r = \frac{5.2^2-5^2}{5.2-5} \\r=10.2\ in^2/in](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B5.2%5E2-5%5E2%7D%7B5.2-5%7D%20%5C%5Cr%3D10.2%5C%20in%5E2%2Fin)
For x = 5 and 5.02
![r = \frac{5.02^2-5^2}{5.02-5} \\r=10.02\ in^2/in](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B5.02%5E2-5%5E2%7D%7B5.02-5%7D%20%5C%5Cr%3D10.02%5C%20in%5E2%2Fin)
b. The instantaneous rate of change in area with respect to x is given by:
![f'(x)=2x](https://tex.z-dn.net/?f=f%27%28x%29%3D2x)
For x = 5
![f'(5) =2*5 = 10\ in^2/in](https://tex.z-dn.net/?f=f%27%285%29%20%3D2%2A5%20%3D%2010%5C%20in%5E2%2Fin)
