Jivesh is analyzing the flight of a few of his model rockets with various equations. In each equation, h is the height of the rocket in centimeters, and the rocket was fired from the ground at time t = 0, where t is measured in seconds.

For Jivesh's Model A rocket, he uses the equation h = −90t^2 + 240t. When is the height of the Model A rocket 160 centimeters? Round your answers to the nearest hundredth.

After t ≈ [] seconds, the rocket will have reached a height of 160 centimeters.

the answer is a

step-by-step explanation:

39.00 x 24 = total installment price

carrying installment price - cash price

needed to save the .00/

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
