Answer:
120
Step-by-step explanation:
We are given that the function for the number of students enrolled in a new course is .
It is asked to find the average increase in the number of students enrolled per hour between 2 to 4 hours.
We know that the average rate of change is given by,
,
where f(x)-f(a) is the change in the function as the input value (x-a) changes.
Now, the number of students enrolled at 4 = f(4) = = 255 and the number of students enrolled at 2 = f(2) = = 15
So, the average increase = = = 120.
Hence, the average increase in the number of students enrolled is 120.
Base x height divided by 2
10x8=80
80÷2=40
area=40
Answer:So that's the change in Y. Now notice that X is increasing. By one unit each time. So we can calculate the slope. The slope is the change in Y divided by the change in X
Step-by-step explanation:
Answer:
3/2
Step-by-step explanation:
slope=rise/run=30/20=3/2
