Answer:
So the center is at (20,.05) and the radius is 9
Step-by-step explanation:
The equation of a circle can be written in the form
(x-h) ^2 + (y-k) ^2 = r^2
where (h,k) is the center and r is the radius
Lets write our equation in that form
( x-20)^2 + (y-0.05)^2 =81
( x-20)^2 + (y-0.05)^2 =9^2
So the center is at (20,.05) and the radius is 9
Answer:
8
Step-by-step explanation:
Each movie costs $4 since the bill increased by $4 when the customer watched a movie.
$29 - $25 = $4
Create an equality using this information. Solve for x.
25 + 4x > 60
(25 + 4x) - 25 > (60) - 25
4x > 35
(4x)/4 > (35)/4
x > 8.75
Since the bill must stay under $60, round the answer down. The customer can watch 8 movies with the given price range.
