The height h (in feet) of an object t seconds after it is dropped can be modeled by the quadratic equation h = -16t2 + h0, where

Reil [10]

Answer:

The rock will reach to the canyon floor in 3.99 seconds.

Step-by-step explanation:

The height h (in feet) of an object t seconds after it is dropped can be modeled by the quadratic equation

$h=-16t^2+255$

Where, h0 is the initial height of the object.

It can be written as

$h=-16t^2+0t+255$

The height of the object is zero if it will reach to the canyon floor.

$0=-16t^2+0t+255$

Quadratic formula:

$t=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

Here a=-16, b=0 and c=255.

$t=\frac{-0\pm \sqrt{0^2-4(-16)(255)}}{2(-16)}$

$t=\frac{\pm \sqrt{16320}}{-32}$

$t=\pm 3.99$

Time cannot be negative, therefore the rock will reach to the canyon floor in 3.99 seconds.

What is the solution to this equation?

horsena [70]

Answer: 15

Step-by-step explanation:

2x+3(x−10)=45

2x+(3)(x)+(3)(−10)=45

2x+3x+−30=45

(2x+3x)+(−30)=45

5x+−30=45

5x−30=45

5x−30+30=45+30

5x=75

x=15
