Question 5:
Sumi Kato's savings account has a balance of $1,568. After 6 years what will the amount of interest be at 5.5% compounded annually? Round to the nearest cent.

Select one:
$2162.025

$583.277
$940.805

Question 6:

Consider the function f(x) = 4x3 - 6x on the interval [ - 4, 4]. Find the average or mean slope of the function on this interval.

By the Mean Value Theorem, we know there exists at least one c in the open interval ( - 4, 4) such that f ' (c) is equal to this mean slope.

For this problem, there are two values of c that work.

The smaller one is

and the larger one is
