Answer:
slope = -1/4
y-intercept = 8
Step-by-step explanation:
In the equation y = -1/4 x + 8
The slope is -1/4 and the y-intercept is 8.
Linear equations are written like "y=mx + b"
"m" stands for slope.
"b" stands for y-intercept.
Answer:
Annual: $302 737.50
Continuous: $332 507.52
Step-by-step explanation:
A. Compounded annually
The formula for <em>compound interest</em> is
A = P(1 + r)ⁿ
Data:
P = $45 000
r = 10 %
t = 20 yr
Calculations:
n = 20
A = 45 000(1+ 0.10)²⁰
= 45 000 × 1.10²⁰
= 45 000 × 6.727 499 95
= $302 737.50
B. Compounded continuously
The formula for <em>continuously compounded inerest</em> is



= 45 000 × 7.389 056 61
= $332 507.52
