First, find the area of the triangle. The height is 9 and the base is 33. So, multiply the base times height, which is 297. Now, divide 297 by 2. This equals 148.5. Secondly, find the area of the rectangle. Multiply the length times the width. 38•20= 760. Now, add the areas of the two shapes. 148.5+760= 908.5. So, 908.5 is your final answer. :)
Hope this helps!

When a certain prescription drug is taken orally by an adult, the amount of the drug (in mg/L) in the bloodstream at t hours is

castortr0y [4]

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.
