Step-by-step explanation:
A weather balloon is released and rises vertically such that its distance s (t) above the ground during the first 10 sec of flight is given by :
...(1)
(a) We need to find velocity at t = 4 seconds
Differentiate equation (1) wrt t.
At t = 4 seconds,
At t = 4 seconds, the velocity is 10 ft/s.
(b) When the balloon is 50 feet above the ground,
We need to find t.
It is a quadratic equation,
t = 5.708 and t = -7.708
Neglecting negative time, the instant time is 5.708 seconds.

Answer:
<u>The radius of the base circle has to be 1.51 inches</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Height of the ice cream package = 4 inches
Volume of the ice cream package = 1 pint = 16 fluid ounces
2. What does the radius of the base circle have to be?
Let's calculate the volume of the ice cream package, as follows:
16 fluid ounces = 16 * 1.8 inches³
Volume = 28.8 inches³
Let's recall the formula of the volume of a cylinder:
Volume = π * r² * h
Replacing with the values we have:
28.8 = 3.1416 * r² * 4
28.8 = 12.57 r²
r² = 28.8/12.57
r² = 2.29
√ r² = √2.29
<u>r = 1.51 inches</u>
