The area you’re looking for is equal to four lateral faces and one bottom face.
Each lateral face has area , and the base has area x^2 , so the total area
you’re looking for is
33 . D
Expand, cancel, and simplify:
That’s the same as (D), (n + 1)^2.
34 . C
Plug P = 4,000, t = 36 , and r = 0.01 into the formula and calculate:
35 . D
First find the distance from the starting point to the endpoint. The starting point is the y-
intercept, which is easy to get if you put the given equation in slope-intercept form:
The y-intercept is the point (0,6). The x-intercept is the point at which y = 0:
