Answer: if S is the distance, the fact that the distance is proportional to the square of the time means that S(t) = a* where a is a constant of proportionality, with units of .
We know that S(1) = 16 feet = a*1, then a = 16
then S(2) = 16*4 feet = 64.
and if we want to know in how much time te objet will fall 400feet, then S(t₀) = 400 feet = 16*
so t₀ = = 5s.

Answer:
117.3 ft³
Step-by-step explanation:
The equation for the volume of a cone of radius r and height h is
V = (1/3) π r² h.
Here, V = (1/3) π (4 ft)² (7 ft) = 117.3 ft³
Answer: 42in
Step-by-step explanation: 7in times 6 sides= 42 in
Answer:
$28.91
Step-by-step explanation:
The first step is to calculate the amount of the tip. You multiply the price (24.50) by the tip amount (18% or 0.18). The product is 4.41. Then, you add the tip to the bill. 24.50+4.41=28.91.
