Answer:

The coordinates of the midpoint of the two vertices are

(0,2) (Third option)

Step-by-step explanation:

<u>Coordinates Of A Midpoint </u>

Given a pair of points in the plane

\displaystyle P_1\ (x_1,y_1)\ ,\ P_2(x_2,y_2)

the coordinates of the midpoint of both points are

\displaystyle x_m=\frac{x_1+x_2}{2}

\displaystyle y_m=\frac{y_1+y_2}{2}

The vertices given in the figure are  

\displaystyle v_1(-4,1),\ v_2\ (4,3)

So the x-coordinate of their midpoint is

\displaystyle x_m=\frac{-4+4}{2}=\frac{0}{2}=0

And the y-coordinate of their midpoint is

\displaystyle y_m=\frac{1+3}{2}=\frac{4}{2}=2

So the coordinates of the midpoint of the two vertices are

(0,2), the third option

Determine how long it will take an object to rotate through 20.0 revolutions at an angular velocity of 2.8 radians per second. U
Andreyy89
The conversion factor between radians and revolution as measures of angle is 2π rad is equal to 1 revolution. Converting the given angular velocity to rev/s,
                (2.8 rad) x (1 rev / 6.28 rad) = 70/157 revolution per second
Dividing the given angle, 20 rev by the velocity,
                                 (20 rev) / (70/157 rev/s) = 44 6/7 s
Thus, the answer is approximately 44.9 seconds.
