Answer:

It landed at a height of 14 feet

Step-by-step explanation:

Given

$y = -\frac{1}{8}x^2 +4x$ --- Path of a t-shirt

$3y = 2x - 14$ --- height of bleachers

Required

Height when t-shirts land in bleachers

$3y = 2x - 14$

Make y the subject

$y = \frac{2}{3}x - \frac{14}{3}$

Substitute $y = \frac{2}{3}x - \frac{14}{3}$ in $y = -\frac{1}{8}x^2 +4x$

$\frac{2}{3}x - \frac{14}{3} = -\frac{1}{8}x^2 +4x$

Multiply through by 24

$16x- 112 = -3x^2 +96x$

Express as:

$3x^2 + 16x -96x- 112 = 0$

$3x^2 -80x- 112 = 0$

Using a calculator:

$x = 28$ or $x = -\frac{4}{3}$

x can not be negative:

So:

$x = 28$

Substitute $x = 28$ in $y = -\frac{1}{8}x^2 +4x$ to calculate the height it landed

$y = -\frac{1}{8} * 28^2 + 4 * 28$

$y = 14$

Gnom [1K]

A' (3(-5),3(-4))= (-15,-12)

B' (3(2),3(6))=(6,18)

C'(3(4),3(-3))=(12,-9)

The washington family is having a new house built. they are trying to decide what type of material to use for the outside of the

Y_Kistochka [10]

2/5

Reason being there are 5 options, we know 2 of those options will likely be chosen, so we divide 2/5 (but that’s the lowest probability because 2 can’t go into 5 making 2/5 our answer)

Which graph represents the function f(x)=4 / x

REY [17]

Answer: The graph of rectangular hyperbola represents the function f(x)=4/x.

Explanation: given function, f(x)= 4/x.

The above function shows equation of rectangular hyperbola or equilateral hyberbola.(because, it is the type of $xy=c^2$ .)

Thus, the asymptote of the given function must be perpendicular.

Moreover, if x=2, y=2, if x=-2, y=-2

If x=4, y=1, if x=-4, y=-1

Therefore, this hyperbola is passing through points (2,2), (-2,-2), (4,1) and (-4,-1).
