Answer:
The time after which the rocket hit the ground is 5 seconds
Step-by-step explanation:
Given as :
The distance of the cover by rocket at the height h = - 16 t² + 160 t
Let the time after which rocket hit the ground = T seconds
Now, When the rocket hits the ground, then at that time, the velocity of the rocket becomes zero.
I.e velocity =
= 0
Or, v =
= 0
Now, v =
Or, v = 
or, v = - 32 t + 160
Now, ∵ velocity of rocket after reaching the ground becomes zero
So, v = - 32 t + 160 = 0
Or, 32 t = 160
Or, t = 
∴ t = 5 sec
So, The time after which the rocket hit the ground = 5 sec
Hence The time after which the rocket hit the ground is 5 seconds answer
Answer:G
Step-by-step explanation:Since it is decreasing in size, the coordinates have to be negative so the only answer is G
Answer:
or 10×10×10×10×10
Step-by-step explanation:
Step-by-step explanation:
Simplifying
4x + -14 = 2x + 8
Reorder the terms:
-14 + 4x = 2x + 8
Reorder the terms:
-14 + 4x = 8 + 2x
Solving
-14 + 4x = 8 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-14 + 4x + -2x = 8 + 2x + -2x
Combine like terms: 4x + -2x = 2x
-14 + 2x = 8 + 2x + -2x
Combine like terms: 2x + -2x = 0
-14 + 2x = 8 + 0
-14 + 2x = 8
Add '14' to each side of the equation.
-14 + 14 + 2x = 8 + 14
Combine like terms: -14 + 14 = 0
0 + 2x = 8 + 14
2x = 8 + 14
Combine like terms: 8 + 14 = 22
2x = 22
Divide each side by '2'.
x = 11
Simplifying
x = 11
