The midpoint formula is just another version of the pythagorean theorem, and it states that the midpoint between (x1,y1) and (x2,y2) is $\left(\frac{x_1+x_2}{2}\right),\:\left(\frac{y_1+y_2}{2}\right)$

Substituting what we know:

endpoint S is (3,2) and endpoint T is (x2,y2)

Midpoint Z is (3,9). We will apply the formula -- backwards.

$\left(\frac{3+x_2}{2}\right)=3$ , solving with algebra we get x2 = 3

So the x-coordinate of endpoint T is 3.

$\left(\frac{2+y_2}{2}\right)=9\quad$ , solving with algebra, we get y2 = 16.

So the y-coordinate of endpoint T is 16.

So the location of endpoint T is (3,16)

A rectangular area of 2,000 square feet is to be fenced on three sides with fence costing $0.30 per foot and on the fourth side

algol [13]

2000 = x * y
y = 2000 / x

c = 0.3 * (2y + x) + 0.5x = 0.6y + 0.8x = 0.6 * 2000 / x + 0.8x = 1200/x + 0.8x
