Answer:
positive
Step-by-step explanation:
it is positive
3 pounds = 1.5 kilograms
so 9 pounds = 1.5 * 3 = 4.5 kilograms
3.5 · 10⁻² · 2.64 · 10²⁰
= 3.5 · 2.64 · 10²⁰⁻²
= 9.24 · 10¹⁸
Answer:
Step-by-step explanation: The area of a circle can be found with the equation A=(pi)*r^2. Use the equation to find the answer:
A=(pi)*5.5^2 (or A=3.14*5.5^2)
A=94.99 or 95.03 in exact pi
Have a nice day! :)
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.
