A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 3 feet, 55 feet awa

tatuchka [14]

Answer:

Second puck travels farther

Step-by-step explanation:

Maximum height of first puck = 3 feet

The height of a second hockey puck is modeled by:

$y=x\left(0.15-0.001x\right)$

$y=0.15x-0.001x^2$

To find maximum height of second puck

$y'=0.15-0.002x$

Equate the derivative equals to 0

0.15-0.002x=0

$\frac{0.15}{0.002}=x$

75 = x

At x = 75

$y=0.15(75)-0.001(75)^2=5.625$

So, The maximum height of second puck is greater than first puck

So, Second puck travels farther

[improper fraction]

$4 \frac{8}{13}$

[mixed fraction]

$4.\overline{615384}$

[decimal]

Explanation:

$\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a}{b} × \frac{d}{c} = \frac{ad}{bc}$

12/13 divided by 3/15 →

$\frac{\frac{12}{13}}{\frac{3}{15}}$ →

$\frac{12}{13} × \frac{15}{3}$ →

$\frac{12}{13} × 5$ →

$\frac{60}{13}$
