The equation of a circle is written as (x – h)^2 + (y – k)^2 = r^2
h and k are the center point and r is the radius.
In the given equation h = -6 and k = 7 and r would be the square root of 81, which is 9.
Center (-6,7)
Radius = 9
Answer:
$.56
Step-by-step explanation:
The first minute is .50 cents and the subtotal was 5.60. Subtract for the first minute to get the subtotal for 9 minutes.
(5.60-.50=5.10)
5.10 is the amount for 9 minutes so now we will divide to get the price for each minute.
(5.10÷9=.56)
This means each minute after the first minute is $.56 cents.
