It is b. 48 because f(x) is 3
Answer:
78 255.20
Step-by-step explanation:
The formula for compound interest is:
A = P(1 + r)ⁿ
Data:
P = 58 000
APR = 3.75 %
t = 8 yr
Calculations:
n = 8 × 12 = 96
r = 0.0375/12 = 0.003 125
A = 58 000(1+ 0.003 125)⁹⁶
= 58 000 × 1.003 125⁹⁶
= 58 000 × 1.349 2275
= 78 255.20
Your balance will be 78 255.20.
Answer: The length of the side of the square poster is 8 feet
The length of the side of the square sign is 10 feet
Step-by-step explanation:
Let the length of one side of the square poster be x
Let the length of one side of the square sign be y
Since they are both squares, the area of a square is expressed as length^2
A square poster has sides measuring 2 feet less than the sides of a square sign. It means that
y = 2+x
If the difference between their areas is 36 square feet, it means that
y^2 - x^2 = 36 - - - - - - - 1
Substituting y = 2 + x into equation 1, it becomes
(2+x)^2 - x^2 = 36
4 + 4x + x^2 - x^2 = 36
4x = 36 - 4 = 32
x = 32/4 = 8
y = 2 + x = 2 + 8
y = 10
