What’s the equation of a circle with a center of (-3,12) that passes through the point (3,4)

(x+3)^2 +(y-12)^2 = 10^2

or

(x+3)^2 + (y-12)^2 = 100 (if simplified radius needed).

Step-by-step explanation:

-The equation of a circle is:

where the center (h, k), the point (x, y) and radius .

-Put the center and the point onto that equation, in order to solve and get the equation:

-Then, you solve:

so, the result can be:

or

(if simplified radius needed).

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
