In two or more complete sentences, explain how to find the time it takes for a rocket following the path of the
parametric equations, x= 3t2 and y=-4t+ 16, to hit the ground.

After t = 4 the rocket will hit the ground.

Step-by-step explanation:

We are given a parametric equation as x = 3t² and y = - 4t + 16.

If we assume that the x is a measure of horizontal distance, y is the measure of vertical distance and t is the time of travel of the rocket, then by making y = 0, we will get the time to hit the ground.

Hence, - 4t + 16 = 0

⇒ t = 4

Therefore, after t = 4 the rocket will hit the ground. (Answer)

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
