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
Answer:
The normal price of mixer is $150.
Step-by-step explanation:
Given that:
Normal prices are reduced by 15% in sale.
The normal price of mixer is reduced by $22.50
It means that it is the amount of discount.
Let,
x be the normal price of the mixer.
15% of x = 22.50

Dividing both sides by 0.15

Hence,
The normal price of mixer is $150.
It’s the third one because we know that the negative 5 Will be positive in the equation same with the 8 and the radius is 2 so square it and it’s 4
