A potato gun is a device made out of plastic pipe that launches a potato using compressed air. They can be great fun, and even e

snow_tiger [21]

Answer:

The potato is 224 feet in the air after 2.75 second on the way up and after 5 seconds on the way back down.

Step-by-step explanation:

Given : A potato launched by a particular potato gun has a height described by $h ( t ) =-16 t^2+124 t+4$ .

To find : When is the potato 224 feet in the air?

Solution :

When the potato is 224 feet in the air i.e. $h(t)=224$

Substitute in the equation $h ( t ) =-16 t^2+124 t+4$ ,

$224=-16 t^2+124 t+4$

$16t^2-124 t+220=0$

$4t^2-31t+55=0$

Applying quadratic formula, $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Here, a=4, b=-31 and c=55

$t=\frac{-(-31)\pm\sqrt{(-31)^2-4(4)(55)}}{2(4)}$

$t=\frac{31\pm\sqrt{81}}{8}$

$t=\frac{31\pm9}{8}$

$t=\frac{31+9}{8},\frac{31-9}{8}$

$t=5,2.75$

The potato is 224 feet in the air after 2.75 second on the way up and after 5 seconds on the way back down.

Find the volume of this sphere.<br> Use 3 for TT.<br> V V ~ [?]cm3<br> V = nr3<br> r=6cm

Katen [24]

Answer:

$V = 864cm^3$

Step-by-step explanation:

Given

$r = 6$

$\pi = 3$

Required

The volume of the sphere

This is calculated as:

$V = \frac{4}{3} \pi r^3$

So, we have:

$V = \frac{4}{3} *3 *6^3$

$V = \frac{4}{3} *3 *216$

This gives:

$V = 4 *216$

$V = 864$
