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

A decorative floor pattern has 1 red square tile surrounded by 12 blue tiles. Write an expression to show how many total red and
Nonamiya [84]

The general equation is that for every red tile, there must be 12 blue ones.

Algebraically this is expressed as b = 12r where r is red and b is blue. Your teacher might like you to express it as y = 12x where y is blue and x is red. The meaning is the same.

For beginners it might be easier to say b = 12r. So if you have 15 reds then r = 15

b = 12 * r

b = 12 * 15

b = 180 blue tiles.
