A circle is represented by the equation below: (x + 8)2 + (y − 3)2 = 100 Which statement is true?

ss7ja [257]

Answer:

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

Step-by-step explanation:

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

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

The center is the point (-8,3)

The radius is $r=\sqrt{100}=10\ units$

The diameter is two times the radius

$D=2(10)=20\ units$

therefore

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

Approximately three out of every 25 Americans live in California about three out of every 50 Americans live in New York in about

pickupchik [31]

3 out of 25 = 12 out of 100
3 out of 50 = 6 out of 100
2 out of 25 = 8 out of 100
12 + 6 + 8 = 26
100 - 26 = 74%
