Answer:
14.52 seconds.
Step-by-step explanation:
We have been given that the height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation
. We are asked to find the time, when the rocket will hit the ground.
We know that the rocket will hit the ground, when height will be 0. So to find the time when rocket will hit the ground, we will substitute
in our given equation as:

Let us solve for x using quadratic formula.








Upon rounding to nearest 100th of second, we will get:

Since time cannot be negative, therefore, the rocket will hit the ground after 14.52 seconds.

Answer:
$221
Step-by-step explanation:
First we need to find what is 35% of 340. To do this, we multiply 340 by 0.35. This gives us 119. Because this is the amount they are taking off, we need to subtract it from the initial price. 340-119=221. Therefore the price after being marked down is $221 :)
