HELP ME DO THIS PLZ

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

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

$y = 14$

3241004551 [841]

Answer:

BDG≅FJM

Step-by-step explanation:

<u><em>The options of the question in the attached figure</em></u>

we know that

If two triangles are congruent, then their corresponding angles and corresponding sides are congruent

BD≅FJ ----> BD and FJ are corresponding sides

DG≅JM ---> DG and JM are corresponding sides

GB≅MF ---> GB and MF are corresponding sides

then

∠B≅∠F ----> ∠B and ∠F are corresponding angles

∠D≅∠J ---> ∠D and ∠J are corresponding angles

∠G≅∠M ---> ∠G and ∠M are corresponding angles

therefore

BDG≅FJM

Answer:

Step-by-step explanation:

Hurley drank between 4 and 5 liters of water for 8 different days and drank between 1 or 2 liters of water on 4 different days. To find the answer we have to use the following equation.

# of days Hurley drank (4-5 L) - # of days Hurley drank (1-2 L) = # of more days

8 - 4 = 4
