padilas [110]

Answer:

<em>The ball will take 8.90 seconds to hit the ground.</em>

Step-by-step explanation:

The height of a ball after t seconds is given by:

$h(t)=40t-5t^2$

Determine how long will the ball take to hit ground level. Since the gound is 40 meters below the throwing point:

$40t-5t^2=-40$

Rearranging:

$5t^2-40t-40=0$

Simplifying by 5:

$t^2-8t-8=0$

Solving the quadratic equation with the formula:

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

With a=1, b=-8, c=-8

$\displaystyle t=\frac{8\pm \sqrt{64+32}}{2}$

$\displaystyle t=\frac{8\pm \sqrt{96}}{2}$

There are two solutions:

t=8.90 sec, t=-0.90 sec

Due to the nature of the problem, t cannot be negative, thus:

The ball will take 8.90 seconds to hit the ground.

Marizza181 [45]

Answer:

y = 2x

Step-by-step explanation:

Maria uses 2 centimeters of tape for each present she wraps, and we want a equation that shows the relationship between the number of presents x and the tape used y. To do this, we can establish a rule of three with the information given:

1 present wrapped -> 2 centimeters of tape

x presents wrapped -> y centimeters of tape

1/x = 2/y

x = y/2 -> y = 2x

From this relation, we know that to make x presents, Maria will use 2x centimeters of tape.
