The number of years it will take to earn his first million is 24 years
Average bi-weekly gross pay = $1,630
Bi-weekly = 2 weeks
Number of 2 weeks(bi-weeks) in a year = 26 bi-weeks
The least million he can earn is $1,000,000
Let the number of years = n
We could use the equation :
Least million = gross pay × (Number of bi-weeks × number of years)
1000000 = 1630 × (26n)
1000000 = 42380
Divide both sides by 34230
1000000 / 42380 = n
n = 23.59
The least number of years is 24.

Answer:
If two points pass through each other it means that it is not a function. The vertical line test shown proves that fact.
Step-by-step explanation:
Suppose

if a>0 it has min if 0>a it has max
The area of a circle is pi x radius^2
The radius is 5 (half of the diameter)
So pi x 25 is 25pi^2.
