Perimeter of figure EFGH=10,because they say that figure ABCD is similar t
o figure EFGH.Side BC is twice bigger than side FG and by knowing that it means that the perimeter of figure EFGH is half of the perimeter of figure ABCD,which is 20/2 and that gives 10.I hope it helped.. :-)

A half ball is hit with an initial vertical veolicty of 68 ft/sec. The function h=-16t^2+68t models the height h (in feet) of th
yan [13]

Answer:

Yes; at 1.75 s; 72.25 ft

Step-by-step explanation:

h = -16t² +68t

a = -16; b = 68; c = 0

The vertex h of a parabola is at

h  = -b/(2a) and the maximum height is at

y = f(h)

1. Time to maximum height

t = -\dfrac{b}{2a} = -\dfrac{68}{2\times(-16)} = \dfrac{68}{32} = \textbf{2.125 s}

2. Maximum height

\text{Height} = f(2.125) = -16(2.125)^{2} + 68(2.125) = -72.25  + 144.5 = \textbf{72.25 ft}

3. Does the golf ball reach 70 ft?

Yes, it passes 70 ft on the way to its maximum height of 72.25 ft.

4. Time to 70 ft

      -16t² + 68t = 70

-16t² + 68t - 70 = 0

   8t² -34t + 35 = 0

  ( 4t -7) (2t - 5) = 0

4t - 7 = 0          2t - 5 = 0

    4t = 7                2t = 5

      t = 1.75 s          t = 2.5 s

The golf ball reaches 70 ft at 1.75 s on the way up and 2.5 s on the way down.

The diagram below shows the path of your parabola.
