What is the center of the circle with the following equation (x+1)²+ (y-3)²= 64? *
(1,3)
(3,1)
(-1,3)
(1,-3)

The center of the circle is (-1,3).

Step-by-step explanation:

The equation of a circle:

where center is known as and the radius known as .

-The following equation:

-So, according to the following equation, the center would be (-1,3), because the center is , based on the equation of a circle:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
