Answer:
I'll setup the problem and you can do the calculations
Step-by-step explanation:
The formula for simple interest:
I = P*r*t
I = interest
P = principle or amount invested
r = interest rate per period (period is a year)
t = number of periods
P = 4920
r = .13
t = 8

The base is the length of the bottom, from x=-4 to x=2, or 6.
The height is the change in y, from y=5 at the top to y=1 at the bottom, so 4.
Area is base times height, 6 × 4 = 24
24
Second choice
380.13
A = πr² = π × 11² ≈ 380.13
slope = -2
y2 - y1 over x2 - x1
so do
7-3/ 2-4 = your slope
4/-2
- 1
=
= - 1
