Write the equation in standard form for a circle that has a diameter with endpoints (8,0) and (-8,0)
riadik2000 [5.3K]

Answer:

x²+y² = 64

Step-by-step explanation:

The standard form of writing the equation of a circle is expressed as;

(x-a)²+(y-b)² = r² where;

(a, b) is the centre of the circle

r is the radius of the circle

Given the diameter of the circle with endpoints (8,0) and (-8, 0)

d = √(x2-x1)²+(y2-y1)²

d = √(-8-8)²+(0-0)²

d = √(-16)²

d = √256

d = 16

radius r = 16/2

r = 8

The centre of the circle will be the midpoint of the coordinates

M = (8-8/2, 0+0/2)

M = (0/2, 0/2)

M = (0,0)

Hence the centre is at (0,0)

Get the required equation

Recall that (x-a)²+(y-b)² = r²

Substitute the centre and the radius

(x-0)²+(y-0)² = 8²

x²+y² = 64

This gives the required equation

9. The first of three numbers is 12 more than the 2nd number and the 3rd number is triple the 2nd number. Their sum is 204 . Wha
Marianna [84]

Answer:

1) 50.4

2) 38.4

3) 115.2

Step-by-step explanation:

1) x+12

2) x

3)3x

X+12+x+3x = 204

5x=204-12

5x=192

x = 192/5

x = 38.4

1) 38.4 +12=50.4

2) 38.4

3) 3*38.4 = 115.2

50.4+38.4+115.2 = 204
