At a basketball game, members of the Spirit Club use a t-shirt cannon to launch team t-shirts to spectators in the stands.
The equation below describes the height, h, of the t-shirt, t seconds after it is shot from the cannon cfeet above the
ground, at an initial velocity of v.
h-162 + vt + c
1. Solve the equation for initial velocity, V.
2. The cannon launched a t-shirt from an initial height of 5 feet. After 3 seconds the shirt has reached a height of 131
feet. Use your equation from #1 to find the initial velocity of the t-shirt. Show your work.
3. What does the equation from #1 tell you about the value of the velocity, V, when t=0? Explain.

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

i cant fully remember all of the ranks, here are the ones i remember.

hand, ambitous, ace, genius.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
