Point A is at (3, -8) and point B is at (7, 3). Point M is the midpoint of point A and point B.
IgorC [24]

The midpoint of point A and point B is (5, -2.5)

<h3>How to determine the midpoint?</h3>

The coordinates are given as:

A = (3, -8)

B = (7, -3)

The midpoint is calculated as:

(x, y) = 0.5 * (x1 + x2, y1 + y2)

So, we have:

(x, y) = 0.5 * (3 + 7, -8 + 3)

This gives

(x, y) = 0.5 * (10, -5)

Evaluate

(x, y) = (5, -2.5)

Hence, the midpoint of point A and point B is (5, -2.5)

After 9 months, the simple interest earned on an investment of $1200 is $72. find the interest rate.
Deffense [45]
Use the formula i=prt, where i is the interest earned, p is the principal, r is the rate (as a decimal fraction) and t is the elapsed time, in years.

Here i = $72 = $1200 r (9/12)                    (9 months is 9/12, or 3/4, of 1 year)
Reducing, 
              $72 = $900r
                                          Solving for r, r=0.08, or 8 percent per year.
