What are the coordinates of the midpoint of ab where a(−7, 2) and b(5, −9)?

(−2.5, −1)

(−6, −5.5)

(−1, −3.5)

(1, −9)

Step-by-step explanation:

Let

M-------> the midpoint of AB

Step 1

Find the x-coordinate of the midpoint AB

we have

substitute

Step 2

Find the y-coordinate of the midpoint AB

we have

substitute

therefore

the coordinates of the point M are

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
