A rocket is launched from the top of a 30 foot cliff with an initial velocity of 150 feet per second. The height, h, of the rocket after t seconds is given by the equation
h = - 1672 +150t + 30. How long after the rocket is launched will it be 20 feet from the ground?

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

$79500

step-by-step explanation:

the answer is 21%.

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
