Answer:
Step-by-step explanation:
Remember that
Using proportion
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:
The answer is: 5.
Step-by-step explanation:
Set up an equation:
2 / 7 = y / 17.5
Cross multiply:
7y = 2 * 17.5
7y = 35
y = 35 / 7 = 5
From the given table, we have two points : (1,29) and (2,47).
Now let us use slope formula to find the slope :
slope =18
Now we use point slope form to get the final equation.
Using point (1,29) and slope 18,
So final equation becomes c=18d +11
