The coordinates of the endpoints of the diameter of a circle are (-1,5) and (3, -1). The center of the circle has coordinates

ans=(-2,2)

Step-by-step explanation:

let the end point of circle diameter (-1,5) and (3,-1) be (x1,y1) and (x2,y2) respectively

using mid point formula

(x,y)=(-1,5)/2+(-3,-1)/2  [center point is equal to mid point of  diameter)

       =  (-1+(-3))/2+(5-1)/2

       =(-2,2)

center coordinate of circle=(-2,2)

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
