Pierre throws a snowball up in the
erastovalidia [21]

Using the given function, it is found that the snowball traveled 4 feet when the height is 20 feet.

<h3>What is the function for the ball's height?</h3>

The height when x feet are traveled is given by:

h(x) = -0.5x² + 6x + 4.

When the height is of 20 meters, we have that h(x) = 20, hence:

20 = -0.5x² + 6x + 4.

0.5x² - 6x + 16 = 0

x² - 12x + 32 = 0

(x - 8)(x - 4) = 0

For the first time: x - 4 = 0 -> x = 4.

The snowball traveled 4 feet when the height is 20 feet.

How big is earth compared to Jupiter
Mashutka [201]
Jupiter has a diameter of about 88,695 miles (142,800 kilometers) which is more than 11 times the diameter of Earth. It’s volume is over 1,300 times the volume of Earth. This mean that Jupiter is so big that over 1,300 Earth could fit inside of it.

9 exponent 10<br> Divide by 9 exponent 11
Natasha_Volkova [10]

Answer:

\frac{\sqrt{110} }{11} or \frac{\sqrt{10} }{\sqrt{11} }

Step-by-step explanation:

I assume you mean \frac{9\sqrt{10} }{9\sqrt{11} }

there is a common factor of 9 in the numerator and denominator so we can cancel out to form \frac{\sqrt{10} }{\sqrt{11} }

\frac{\sqrt{10} }{\sqrt{11} } is technically a correct answer, but I will go ahead to rationalize the denominator

multiply \frac{\sqrt{10} }{\sqrt{11} } by some form of 1. this case, we will use \frac{\sqrt{11} }{\sqrt{11} } as our 1.

\frac{\sqrt{10} }{\sqrt{11} }*\frac{\sqrt{11} }{\sqrt{11} } = \frac{\sqrt{10} *\sqrt{11} }{\sqrt{11} *\sqrt{11} } = \frac{\sqrt{110} }{11}
