Answer:

a) x-intercepts are (0,0) and (5,0)

b) 6.25 yards

Step-by-step explanation:

a) x intercepts are:

-x² + 5x = 0

-x(x - 5) = 0

x = 0, 5

b) -x² + 5x

-(x² - 5x)

-[x² - 2(x)(5/2) + (5/2)² - (5/2)²]

-(x - 5/2)² + 25/4

Max height is:

25/4 yards or 6.25 yards

Answer:

1. $\frac{3}{8}$

2. $\frac{1}{4}$

3a. $-\frac{1}{4}$

3b. 3

3c. $-\frac{4}{5}$

4. $m = \frac{y_1 - y_2}{x_1-x_2}\\$

Step-by-step explanation:

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

$m = \frac{y_1 - y_2}{x_1-x_2}$

$m = \frac{3-2}{-2-2}$

$m = \frac{1}{-4}$

$m = -\frac{1}{4}$

3b.

$m = \frac{y_1 - y_2}{x_1-x_2}\\$

$m = \frac{-1 - 2}{-1-0}$

$m = \frac{-3}{-1}$

$m = 3$

3c.

$m = \frac{y_1 - y_2}{x_1-x_2}\\$

$m = \frac{1 - (-3)}{-1-4}\\$

$m = \frac{4}{-5}\\$

$m = -\frac{4}{5}$

$m = \frac{y_1 - y_2}{x_1-x_2}\\$
