Answer:
Step-by-step explanation:
Given circle has equation as

Center = P(0,0)
The point of contact of tangent =
Q
Since tangent is perpendicular to the radius at the point of contact, we have
Slope =
as slope of perpendicular to tangent
So tangent slope would be
-1/slope of this line
= 
We have point on this line as given point
So using point slope form equation of tangent is

Step-by-step explanation:
39.375 miles............
If you take 2/5 minus 8/10 the final results would be -2/5 and it equals -0.4.
Answer: Zero slope.

Answer:
The APR of the loan was 18.30%.
Step-by-step explanation:
Given that a student has a total of $ 3000 in student loans that will be paid with a 48-month installment loan with monthly payments of $ 73.94, to determine the APR of the loan to the nearest one-half of a percent the following calculation must be done:
3,000 = 100
(73.94 x 48) = X
3,000 = 100
3,549.12 = X
3,549.12 x 100 / 3,000 = X
354,912 / 3000 = X
118.30 = X
118.30 - 100 = 18.30
Therefore, the APR of the loan was 18.30%.
