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

so

The center is the point (-8,3)

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

so

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

What’s the slope intercept form of (2,5) and (0,1)
Travka [436]

Answer:

y=2x+1

Step-by-step explanation:

First you have to find the slope:

5-1/2 so 4/2 or 2

Then you write it in point-slope: (I used the point (0,1))

y-1=2x

Simplify than:

y=2x+1

Please help if u answer with a answer that is trolling I will report you
algol13

Answer:

230.5

Step-by-step explanation:

Formulas: a = 1/2(bh), a = bh

Rectangle 1: a = 6 x 8

a = 48

Base of the triangle: 9 + 6

15

Triangle 1: a = 1/2(15 x 24)

a = 180

Triangle 2: a = 1/2(4(13 - 8))

a = 2.5

48 + 180 + 2.5

230.5

<u>The area of the figure is 230.5.</u>
