Approximately 10 weeks. To be specific, 9.71 of a week.
He is wrong because as long as they have the same terms/ variables behind the number it doesn’t matter about if it is positive or negative
Answer:
C. dL/dt=k(100−L)
Step-by-step explanation:
The rate of change of the number of words memorized is proportional to the number of words left to be memorized.
The rate of change is dL/dt.
The rate is a constant k. Since the rate is proportional to the number of words left to be memorized, and the initial number of words is 100, k has to be multiplied by (100-L).
So the correct answer is:
C. dL/dt=k(100−L)
Answer:
800 cm^3
Step-by-step explanation:
An easy way is to cut the base up into two parts. Take a look at the drawing I added below for explanations!
Rectangle ACDG has an area of 28.
--> (12-5)(4) = (7)(4) = 28
Rectangle BFEG has an area of 72.
--> (10-4)(12) = (6)(12) = 72
So the total area of the base is 28 + 72 which is 100.
Base x Height is the volume, so it will be 100 x 8 (The height) = 800
So 800 cm^3 is your answer!
