Answer:
A. ![\frac{-11}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B-11%7D%7B4%7D)
Remember that if f and g are functions with
then,
.
Then,
![\frac{d}{dx}\frac{h(x)}{x}=\frac{h'(x)x-h(x)}{x^2}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdx%7D%5Cfrac%7Bh%28x%29%7D%7Bx%7D%3D%5Cfrac%7Bh%27%28x%29x-h%28x%29%7D%7Bx%5E2%7D)
Evaluating in x=2,
![\frac{h'(2)*2-h(2)}{2^2}=\frac{-4-7}{4}=\frac{-11}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bh%27%282%29%2A2-h%282%29%7D%7B2%5E2%7D%3D%5Cfrac%7B-4-7%7D%7B4%7D%3D%5Cfrac%7B-11%7D%7B4%7D)
Then the answer is A.
Diameter of 10 in= Radius of 5 in
Area of circle= pi*r^2
Area= 3.14*5^2
Area= 3.14*25
Area= 78.5
Final answer: C
Answer:
$500
Step-by-step explanation:
1000x.05=50 per year
50/year x 10 years =500
