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.
Answer:
c4+8c3+−3c2+−7c
Step-by-step explanation:
Let's simplify step-by-step.
−3c4−5c2−7c+4c4+8c3+2c2
=−3c4+−5c2+−7c+4c4+8c3+2c2
Combine Like Terms:
=−3c4+−5c2+−7c+4c4+8c3+2c2
=(−3c4+4c4)+(8c3)+(−5c2+2c2)+(−7c)
=c4+8c3+−3c2+−7c
