Answer:
Step-by-step explanation:
<u>Volume of the cone:</u>
<u>Substitute values and solve for r:</u>
- 12π = 1/2πr²(4)
- r² = 9
- x = √9
- r = 3 ft
30% of 1100 is 330. The price (1100) after discount (330) is 770
770$
Step-by-step explanation:
The height of the rocket y in feet is related to the time after launch, x in seconds, by the given equation i.e.
......(1)
It is required to find the maximum height reached by the rocket. For maximum height put
.
So,

Put x = 5.15 in equation (1).

So, the maximum height reached by the rocket is 503.39 m.
