8 A test rocket is fired and follows a path described by y = 0.1x(200 – x). The height is y metres above
balandron [24]

Answer:

a) The rocket travels 200 meters horizontally.

b) The height of the rocket mid-flight is of 1000 meters.

Step-by-step explanation:

Height of the rocket:

The height of the rocket, in meters, after an horizontal distance of x, is given by:

y = 0.1x(200 - x)

a) How far does the rocket travel horizontally?

This is x when y = 0. So

0.1x(200 - x) = 0

Then

0.1x = 0

x = 0

And

200 - x = 0

x = 200

So

The rocket travels 200 meters horizontally.

b How high does the rocket reach mid-flight?

This it the height y when x = 0, so:

y = 20*100 - 0.1*100^2 = 1000

The height of the rocket mid-flight is of 1000 meters.

Over the summer, for every 12 okra seeds Dana planted, 7 grew into plants. If he planted 156 okra seeds, how many grew into plan
drek231 [11]
Set this up as a proportion with seeds on top and plants on bottom.  Ours will look like this: \frac{12}{7}= \frac{156}{x}.  Cross multiply to get 12x=1092.  Divide to get that the number of plants to expect from 156 seeds is 91, choice B from above.
