Is a rectangle with curved angles a polygon
Alik [6]
A polygon must have at least 3 sides, but a curved angle isn't a side. This would result in you getting an oval. In short, it would not be a polygon. Hope this helps!

Tasha wants to graph a line that is parallel to the line with equation y = 3x. Give two examples of linear equations that repres
Arturiano [62]

When two lines are <em><u>parallel, that means they have the same slope! </u></em>

The slope is the coefficient of x

In the equation y = 3x, <u>the slope is 3 </u>

An example of a line that is above y = 3x is ...

y = 3x + 2

The "+2" <em>shifts the line up </em>by 2 on the y axis

An examples of a line that is below y = 3x is ...

y = 3x - 3

The "-3" <em>shifts the line down</em> by 3 on the y axis

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
