Answer:
Option B.
Step-by-step explanation:
Option A.
f(x) = 
Derivative of the given function,
f'(x) = 
= ![(0.5)^x[\text{ln}(0.5)]](https://tex.z-dn.net/?f=%280.5%29%5Ex%5B%5Ctext%7Bln%7D%280.5%29%5D)
= 
Since derivative of the function is negative, the given function is decreasing.
Option B. f(x) = 
f'(x) = 
= ![(5)^x[\text{ln}(5)]](https://tex.z-dn.net/?f=%285%29%5Ex%5B%5Ctext%7Bln%7D%285%29%5D)
= 
Since derivative is positive, given function is increasing.
Option C. f(x) = 
f'(x) = 
= 
= 
Since derivative is negative, given function is decreasing.
Option D. f(x) = 
f'(x) = ![-15^{-x}[\text{ln}(15)]](https://tex.z-dn.net/?f=-15%5E%7B-x%7D%5B%5Ctext%7Bln%7D%2815%29%5D)
= 
Since derivative is negative, given function is decreasing.
Option (B) is the answer.
Its A.) because if you think of a bank it gains interest because you put it in the bank
<span>A stack of 100 pennies, one on top of the other, is 15.5 centimeters tall. </span>
<span>a penny is 1.55 mm thick, so a stack of </span>
<span>100 pennies would be 155 mm thick or 15.5 centimeters. </span>
<span>This means that a stack of 100 pennies is 6.1 inches in height.</span>
Answer:
30 sand bags
Step-by-step explanation:
6 x 10 = 60
180 - 60 = 120
120/5 = 24
