The team mascot shoots a rolled T-shirt from a special T-shirt cannon to a section of people in the stands at a basketball game. The T-shirt starts at a height of 8 feet when it leaves the cannon and 1 second later reaches a maximum height of 24 feet before coming back down to a lucky winner.

A. f(t) = –16(t – 1)2 + 24

Step-by-step explanation:

The team mascot shoots a rolled T-shirt from a special T-shirt cannon to a section of people in the stands at a basketball game. The T-shirt starts at a height of 8 feet when it leaves the cannon and 1 second later reaches a maximum height of 24 feet before coming back down to a lucky winner. If the path of the T-shirt is represented by a parabola, which function could be used to represent the height of the T-shirt as a function of time, t, in seconds?

A. f(t) = –16(t – 1)² + 24

B. f(t) = –16(t + 1)² + 24

C. f(t) = –16(t – 1)² – 24

D. f(t) = –16(t + 1)² – 24

The path of the T-shirt is represented by a parabola. The general equation of a parabola is given by y = a(x - h)² + k with a vertex at (h, k).

The height of the t shirt is a function of the time. Given:

A. f(t) = –16(t – 1)² + 24

At time (t) = 0. Therefore:

f(0) = –16(0 – 1)² + 24  = -16 + 24 = 8 feet.

The vertex of the function is at (1, 24). This means at one second, the maximum height is 24 feet.

This is the correct option

B. f(t) = –16(t + 1)² + 24

At time (t) = 0. Therefore:

f(0) = –16(0 + 1)² + 24  = -16 + 24 = 8 feet.

The vertex of the function is at (-1, 24). This means at -1 second, the maximum height is 24 feet. The function is wrong since the time cnnot be negative

C. f(t) = –16(t – 1)² – 24

At time (t) = 0. Therefore:

f(0) = –16(0 – 1)² - 24  = -16 - 24 = -40 feet.

The vertex of the function is at (1, -24). This means at one second, the maximum height is -24 feet. This is not correct

D. f(t) = –16(t + 1)² – 24

At time (t) = 0. Therefore:

f(0) = –16(0 + 1)² + 24  = -16 - 24 = 8 feet.

The vertex of the function is at (-1, -24). This means at -1 second, the maximum height is -24 feet. This is not correct

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
