every year in delaware there is a contest where people create cannons and catapults designed to launch pumpkins as far in the air as possible. the equation y = 15 + 110x - 16x^2 can be used to represent the height, y, of a launched pumpkin, where x is the time in seconds that the pumpkin has been in the air. what is the maximum height that the pumpkin reaches? how many seconds have passed when the pumpkin hits the ground? (hint: if the pumpkin hits the ground, its height is 0 feet)

a. the pumpkins maximum height is 204.06 feet and it hits the ground after 7.01 seconds.

b. the pumpkins maximum height is 3.44 feet and it hits the ground after 7.01 seconds.

c. the pumpkins maximum height is 204.06 feet and it hits the ground after 3.44 seconds

d. the pumpkins maximum height is 3.44 feet and it hits the ground after 204.05 seconds.

Use this picture to solve for X
Zepler [3.9K]

Answer:

x=2

Step-by-step explanation:

i would set up a system of equation using the pythagorean theorem:

1^2+x^2=z^2

4^2+x^2=y^2

Add up these equations to get:

17+2x^2=y^2+z^2

But notice that

y^2+z^2=5^2

So you can substitute

17+2x^2=25

2x^2=8

x^2=4

x=2

Hello there!
Goryan [66]

(x^2+3)^2 + 7x^2+21=-10

We want to convert this equation in terms of m, where m = x^2+3

While solving this problem, I instantly noticed the x^2+3 in the first term of the equation. Replace that with m.

m^2 + 7x^2+21=-10

Simplifying the rest is not as obvious. Using the distributive property, we can change [7x^2+21] to [7(x^2+3)]

Do you see the "m" in here? Look again if you don't.

Now we can simplify the equation to m^2 + 7m=-10 and this cannot be simplified further.

I'm always happy to help someone who appreciates the help! :D

Eduardo bought 2liter sports drink for soccer practice during practice Eduardo drank 250 millimeters of sport drink then he dran
Jlenok [28]

Answer:

He have left <u>1250 milliliters</u> of sport drink.

Step-by-step explanation:

Given:

Eduardo bought 2 litre sports drink for soccer practice during practice.

Eduardo drank 250 milliliters of sport drink then he drank another 1/2 liter.

Now, to find the milliliter of sport drink he have left.

Eduardo bought sports drink = 2 litre.

Now, to convert litre into milliliter by using conversion factor:

1 litre = 1000 milliliter.

2 liters = 2 × 1000 milliliters.

2 liters = 2000 milliliters.

<u><em>Thus, Eduardo bought 2000 milliliters sport drink.</em></u>

<u><em>As, Eduardo drank 250 milliliters of sport drink.</em></u>

So, to get the sport drink left after he drank we subtract 250 milliliters from 2000 milliliters:

2000-250\\\\=1750\ milliliters.

<u><em>Thus, 1750 milliliters sport drink left.</em></u>

Now, to get the sport drink left after he drank \frac{1}{2} \ liter we subtract \frac{1}{2} \ liter from 1750 milliliters:

\frac{1}{2} \ liter =500\ milliliters.

So,

1750-500\\\\=1250\ milliliter.

Therefore, he have left 1250 milliliters of sport drink.
