Answer:
x= 27
Step-by-step explanation:
Move <u>constant</u> to the right-hand side and change its sign.
= 2+6
Add the numbers.
= 8
Square both sides of the equation.
2x+10= 64
Move the <u>constant</u> to the right-hand side and change its sign.
2x= 64-10
Subtract the numbers.
2x= 54
Divide both sides of the equation by 2.
x= 27
Answer:
t = [0.493,4.2]
Step-by-step explanation:
The height of the rocket straight up into the air is given by :
We need to find the interval the rocket be at least 43 feet above the ground.
So, the required interval during which the rocket is at least 43 feet above the ground is [0.493,4.2].
