6. Two points in the plane, ????(19,4) and ????(19,−6), represent the endpoints of the diameter of a circle.

dusya [7]

Answer:

Radius = 5

center is (19,-1)

$(x-19)^2(y+1)^2= 25$

Step-by-step explanation:

Two points in the plane, (19,4) and (19,−6), represent the endpoints of the diameter of a circle.

Distance between the points is calculated using formula

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$=\sqrt{\left(19-19\right)^2+\left(-6-4\right)^2}=10$

diameter = 10

radius = diameter divide by 2

Radius = 5

midpoint is the center of the circle

$\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)$

$\left(\frac{19+19}{2},\:\frac{-6+4}{2}\right)$

(19,-1)

Equation of the circle

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

h,k is the center and r is the radius

h=19 and k=-1 , r=5

$(x-19)^2(y+1)^2= 25$

Find slope of (-5, 2) and (7,6)

marshall27 [118]

Answer:

1/3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(6-2)/(7-(-5))

m=4/(7+5)

m=4/12

simplify

m=1/3

What value for Y makes the equation true ? 18y + 4 = 130 {5,6,7,8}

Rufina [12.5K]

Answer:

7 is true

Step-by-step explanation:

if y=5, then 94=130, which is false.

If y=6, then 112=130, which is false

If y=8, then 148=130, which is false.

If y =7, 130=130, which is true
