Answer:

The circle is centered at (-8,3) and has a diameter of 20 units

Step-by-step explanation:

<u><em>The correct question is</em></u>

Which is the center and the diameter of the circle?

we know that

The equation of a circle in center radius form is equal to

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

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

(x+8)^2+(y-3)^2=100

so

The center is the point (-8,3)

The radius is

r=\sqrt{100}=10\ units

so

Remember that

The diameter is two times the radius

so

D=2(10)=20\ units

therefore

The circle is centered at (-8,3) and has a diameter of 20 units

Find the y-intercept of each exponential function and order the functions from least to greatest y-intercept.
kvv77 [185]

Answer:

Keep the exact order that is shown

Step-by-step explanation:

The first exponential already has a point at (1, -2) which means the y-intercept would be less than -2, which is the lowest among the three


The second has a y-int at -2

Third has y-int at 2
