Write an equation of the circle with center (-4.8) and radius 9

(x+4)^2 +(y-8)^2 = 81

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- -4)^2 + (y-8)^2 = 9^2

(x+4)^2 + (y-8)^2 = 9^2

(x+4)^2 +(y-8)^2 = 81

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

i can't solve unless i know what the line is
