An object is launched at 19.6 m/s from a height of 58.8 m. The equation for the height (h) in terms of time (t) is given by h(t)
beks73 [17]
H(t) = Ho +Vot - gt^2/2

Vo = 19.6 m/s
Ho = 58.8 m
g = 9.8 m/s^2

H(t) = 58.8 + 19.6t -9.8t^2/2 = 58.8 + 19.6t - 4.9t^2

Maximun height is at the vertex of the parabole

To find the vertex, first find the roots.

58.8 + 19.6t - 4.9t^2 = 0

Divide by 4.9

12 + 4t - t^2 = 0

Change sign and reorder

t^2 - 4t -12 = 0 

Factor

(t - 6)(t + 2) =0 ==> t = 6 and t = -2.

The vertex is in the mid point between both roots

Find H(t) for: t = [6 - 2]/2 =4/2 = 2

 Find H(t) for t = 2

H(6) = 58.8 + 19.6(2) - 4.9(2)^2 = 78.4

Answer: the maximum height is 78.4 m

meema: 48-24/4-2 = 4/2 = 2

papa: 40-24/5-3 = 16/2 = 8

auntie jo: 45-18/5-2 = 27/3 = 9

the hypotenuse of a triangle is one foot more than twice the length of the shorter legal. the longer leg is seven feet longer th
wolverine [178]
8, 15, 17

You can do this by using the Pythagorean Theorem and setting the sides equal to

shorter leg = x
longer leg = x + 7
hypotenuse = 2x + 1

Then solve so that one side is equal to zero and use the quadratic formula.

Answer:

<h3>Question 1 </h3>

<u>Find x</u>

  • 62 + 5x + 3 = 180
  • 5x = 180 - 65
  • 5x = 115
  • x = 23

<u>Find y</u>

  • 62 = 3y + 2
  • 3y = 60
  • y = 20
<h3>Question 2</h3>
  • <em>Diagonals bisect each other</em>

<u>Find x</u>

  • 4x = 3x + 7
  • x = 7

<u>Find y</u>

  • 6y = 2y + 16
  • 4y = 16
  • y = 4

Correct choice is A
