A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by gi
ven equation. Using this equation, find the time that rocket will hit the ground, to the nearest 100th of second. Y=-16x^2+157x+104
1 answer:
The time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds
Given the equation representing the height reached by a rocket as:
The rocket will hit the ground when y = 0. Substituting y = 0 into the expression to get x;
On factorizing:
x = 10.43 seconds
Hence the time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds

Find AB and BC
Case 1:
Using Pythagoras theorem in ANB, we have:
This gives:
Take square roots of both sides
To calculate BC, we consider ANC, where:
Collect like terms
Take square roots
So:
Case 2:
Using Pythagoras theorem in ANB, we have:
This gives:
Collect like terms
Take square roots of both sides
To calculate BC, we consider ABC, where:
Collect like terms
Take square roots
Case 3:
This is not possible because in ANC
The hypotenuse AN (24) is less than AC (40)
