Answer:

  • h = -16t^2 +192t
  • maximum

Step-by-step explanation:

In order to fill in the values in the given function, we need to assume an initial height for the firework. It is convenient to assume that height (h0) is zero. We are given that v0 = 192, so the model is ...

  h = -16t^2 +192t

___

Since the initial upward velocity is well below escape velocity, the firework will eventually fall back to Earth. The height function will have a maximum.

Answer:

\displaystyle h(t) = -16t^2 + 192t; Maximum

Step-by-step explanation:

Maximum Value → Parabola opens downward [<em>−A</em>]

Minimum Value → Parabola opens upward [<em>A</em>]

blsea [12.9K]

Answer:

\boxed{\bf x=7}

\boxed{\bf GH= 52}

Step-by-step explanation:

In the line segment..

\bf 7x+3+3x-5=9x+5

Combine like terms.

  • \bf 10x-2=9x+5

Add -2 to both sides.

  • \bf 10x-2+2=9x+5+2
  • \bf 10x=9x+7

Subtract 9x from both sides.

  • \bf 10x-9x=9x+7-9x
  • \boxed{\bf x=7}

\bf GH=7x+3

  • \bf 7(7)+3
  • \bf 49+3
  • \boxed{\bf 52}

In the given figure, ABCD is a rectangle. Its diagonals meet at O. If OC = 3x – 4, OB = x + 4, then find OB, OC, OA, AC, BD and
Step2247 [10]

Answer:

OB = 8

OC = 8

OA = 8

AC = 16

BD = 16

OD = 8

Step-by-step explanation:

Given, rectangle ABCD, with diagonals AC and BD, and OC = 3x – 4, OB = x + 4,

thus, since diagonals of a rectangle are equal, therefore, AC = BD.

Invariably, 2*OC = 2*OB

Thus, 2(3x - 4) = 2(x + 4)

Solve for x

6x - 8 = 2x + 8

Add 8 to both sides

6x - 8 + 8 = 2x + 8 + 8

6x = 2x + 16

Subtract 2x from both sides

6x - 2x = 2x + 16 - 2x

4x = 16

Divide both sides by 4

\frac{4x}{4} = \frac{16}{4}

x = 4

OB = x + 4 = 4 + 4 = 8

OC = 3x - 4 = 3(4) - 4 = 12 - 4 = 8

OA = OC = 8

AC = 2*OC = 2*8 = 16

BD = 2*OB = 2*8 = 16

OD = OB = 8
