Step-by-step explanation:
1 lb = 0.45359 kg
140 kg * (1 lb)/(0.45359 kg) = 308.65 lb
Answer:
x = 9
Step-by-step explanation:
given f(x) = 3x and f(x) = 27, then equating f(x) gives
3x = 27 ( divide both sides by 3 )
x = 9
Answer:
165
Step-by-step explanation:
The distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds
<u>Explanation:</u>
Given:
Height, h = 75 foot
Initial velocity, u = 107 foot/sec
Equation:
h = -16t² + 107t + 75
Substituting the equation:
75 = -16t² + 107t + 75
0 = -16t² + 107t
16t² = 107t
t = 6.6875s
We know:
Distance = speed X time
d = 107 f/s X 6.6875s
d = 715.56 foot
Therefore, the distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds
