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.

zzz [600]

<span> These are the main data: 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

</span>
So, f(0) = 8 feet and f(1) = 24 feet

That means, that you can evaluate the functions at t = 0 and t = 1 to see which represents those two points, (0, 8) and (1, 24).

A: f(t) = –16(t – 1)^2 + 24

t = 0 => f(0) = - 16 (0 – 1) ^2 + 24 = -16 + 24 = 8 => This is Ok.

t =1 => f(1) = - 16 (1 – 1)^2 + 24 = 0 + 24 => This is Ok.

<span>
B: f(t) = –16(t + 1)^2 + 24</span>

t = 0 => f(0) = -16 (0 + 1)^2 + 24 = - 16 + 24 = 8 => this is Ok

t = 1 => f(1) = -16 (1 + 1)^2 + 24 = -16(4) + 24 = - 64 + 24 = - 40 => Wrong

<span>
C: f(t) = –16(t – 1)^2 – 24</span>

t = 0 => f(0) = -16 (0 – 1)^2 - 24 = -16 – 24 = - 40 => Wrong

<span>
D: f(t) = –16(t + 1)^2 – 24 </span>

t = 0 => f(0) = - 16 (0 + 1)^2 – 24 = -16 – 24 = - 40 => Wrong

With tha we have obtained that the answer is the option A.

Answer:

$h=12.5\ in$

Step-by-step explanation:

we know that

The surface area of a square prism is given by the formula

$SA=2(b^2)+4bh$

where

b is the length side of the square base

h is the height of the prism

we have

$b=5\ in\\SA=300\ in^2$

substitute

$300=2(5^2)+4(5)h$

solve for h

$300=50+20h\\20h=300-50\\20h=250\\h=12.5\ in$

Approximate the real number solution(s) to the polynomial function f(x) = x^3 + 4x^2 + x − 6.

irakobra [83]

Answer:

d. x ∈ {-3, -2, 1}

Step-by-step explanation:

The word "approximate" in the problem statement suggests that the roots may not be integers. Consequently, the solution method of choice is graphing.

A graph shows the solutions to f(x)=0 to be x=-3, x=-2, and x=1, matching selection D.

_____

<em>Comment on the problem statement</em>

Any value of x can be put into the formula and it will be a "solution." For example, f(0) = -6 is a "solution" to the polynomial function. The problem statement is not specific as to the solution(s) sought. We have had to guess that we want values of x such that f(x)=0.
