Answer:
34.54 
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Height (h) = 3.7 km
Base radius (r) = 3 km
We can calculate the volume of mountain by using following formula,
So, volume of cone = (1/3)π
h
By putting the value in the formula, we get
= (1/3) π × 
× 3.7
= 11.1π
= 34.54
Hence, the volume of the mountain is 34.54 .

Answer:
72.9 degrees
Step-by-step explanation:
First we need to calculate the hypothenuse with the teorem of Pythagoras. ZY = sqrt(13^2+4^2) = 13.6 cm. sqrt stands for square root.
The we calculate the cosine of our angle (we could use the sine but I'll use the cosine here, the method is a little different with the sine). For the cosine divide the adjacent side by the hypothenuse: 4/13.6 =0.294
then we use the cos^-1 function on the calculator , so cos^-1(0.294) =72.897 =72.9 degrees.

Answer:
1. y = f(8)
2. So for t which f'(t) > 0, the drug level in the bloodstream is increasing. And for t which f'(t) < 0, it is decreasing.
Step-by-step explanation:
The concentration of the drug in the bloodstream at t hours is:
y = f(t)
1. What is the concentration of the drug in the bloodstream at t= 8 hours?
At t hours, y = f(t)
So at 8 hours, y = f(8)
2. During what time interval is the drug level in the bloodstream increasing? Decreasing?
A function f(t) is increasing when
f'(t) > 0
And is decreasing when
f'(t) < 0
So for t which f'(t) > 0, the drug level in the bloodstream is increasing. And for t which f'(t) < 0, it is decreasing.
