Answer:

- 22.5

Step-by-step explanation:

Substitute x = 3 into f(x) and x = 16 into h(x) , then

\frac{1}{2} g(3) - h(16)

= \frac{1}{2} × - 3(3)² - (2\sqrt{16} + 1)

= \frac{1}{2} × - 3(9) - (2(4) + 1)

= \frac{1}{2} × - 27 - (8 + 1)

= - 13.5 - 9

= - 22.5

All you have to do is multiply the l * w = Area

When you look at 26 ft and 15 ft, 21 ft and 10 ft, 29 ft and 18 ft, you'd know it wouldn't work since it's over 180.

So the dimensions of the ceiling are l = 20 ft; w = 9 ft

What is the midpoint of (8,10) and (-8,8)
nasty-shy [4]

9514 1404 393

Answer:

  (0, 9)

Step-by-step explanation:

The midpoint coordinates are the averages of the end point coordinates.

  M = (A +B)/2

  M = ((8, 10) +(-8, 8))/2 = (8 -8, 10+8)/2 = (0, 18)/2

  M = (0, 9)

The midpoint is (0, 9).
