Sector area = (central angle / 360) * PI * radius^2
sector area = (72 / 360) * PI * radius^2
radius^2 = sector area / [(72 / 360) * PI]
radius^2 = 16.2 * PI / [(1 / 5) * PI]
radius^2 = 16.2 / .2
radius^2 = 81
radius = 9

3x10^-7 = 3 / (10^7) = 3 / 10000000 = 0.0000003;
A number greater then 0.0000003 is 1.
Answer:
$176.3193692 or $176.32 (rounded to two decimal places)
Step-by-step explanation:
It is a compound interest, which means the interest accumulates on an initial amount each period.
The formula is A=P(1+R)^n
A= the total amount P=initial amount R=rate n=time (years)
P=$120 Rate= 8% or 0.08 (decimal) n=5 (years)
A=120 (1+0.08)^2
A=120 (1.469328077)
A= 176.3193692
Domain is everything below 0. Range is all real numbers. It is a function as it passes the vertical line test.
