Answer:

(x-5)^2 + (y+9)^2 = 144

Step-by-step explanation:

The equation of a circle can be written as

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x-5)^2 + (y- -9)^2 = 12^2

(x-5)^2 + (y+9)^2 = 12^2

(x-5)^2 + (y+9)^2 = 144

PLEASE HURRY-When Melissa is playing soccer she makes 2 goals out of every 12 shots on goal. How many times would you expect her
melisa1 [442]

Answer: 24 goals

Step-by-step explanation:

Melissa makes 2 goals out of every 12 shots on goal.

This means that the amount of shots needed to score a goal for her is:

= Number of shots / Number of goals

= 12 / 2

= 6 shots

She scores a goal every 6 shots.

If she makes 144 shots therefore, she will score:

= Number of shots / Number of shots needed per goal

= 144 / 6

= 24 goals

Austin will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $38 and costs an ad
Nana76 [90]
38+0.11m=51+0.09m
0.02m=13
m=650 miles
If Austin will drive more than 650 miles he can choose the second plan of car renting.
If he plan todrive less than 650 miles then it's more preferable to choose the first plan of car renting
