Jivesh brought his Model B rocket on a camping trip near the top of a mountain. He wants to model how it descends down the mount
dybincka [34]

Answer:

i. 1.63 s

ii. The negative time cannot be used in this context

Step-by-step explanation:

i. Since  h = −640t² and the rocket descends 1,690 m, h = -1,690 m (since there is a drop in height).

So,  h = -640t²

t² = h/-640

t = √(- h/640)

Substituting h into the equation, we have

t = √(- h/640)

t = √[-(-1,690)/640]

t = √2.640625

t = 1.625

t ≈ 1.63 s

ii. So, the negative time cannot be used in this context because, the height drop is negative.

The show has a large display board where visitors are encouraged to pin up their own instant camera pictures, taken during the e
arsen [322]

Answer:

<h2>1,800 pictures</h2>

Step-by-step explanation:

Find the diagram attached below with its dimension.

The board is rectangular in nature with dimension of 3.6 m by 1.8 m wall.

Area of a rectangle = Length * Breadth

Area of the board = 3.6 m * 1.8 m

since 1m -= 100cm

Area of the board = 360cm * 180cm

Area of the board = 64,800cm²

If the dimension of a picture on the wall is 6cm * 6cm, the area of one picture fir on the wall = 6cm* 6cm = 36cm²

In order to know the amount of 6cm* 6cm pictures that will fit on the wall, we will divide the area of the board by the area of one picture as shown;

Number of 6cm by 6cm pictures that  could fit on the wall

= 64, 800cm²/36cm²

= 1,800 pictures
