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:
No
Step-by-step explanation:
polynomial does not have any zero terms
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
Step-by-step explanation:
first you have to use the formula for circle is 2πr
22
π= ----
7
and r stands for radius
