In the standard (x, y) coordinate plane, what is the midpoint of the line segment that has endpoint a (3,8) and (1,-4)? The answer is (2, 2) but how do I solve?

Step-by-step explanation:

Given

and

Required

Determine the coordinate of the midpoint (M)

This is calculated as thus:

Where

--

--

So, we have:

Hence, the coordinates of the midpoint is (2,2)

answer:

your answer is: c. 196 7/8 in^3.

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
