This is the equation of an upside down parabola, so the maximum height will be at the vertex. To find the vertex, we'll use the formula for the x-coordinate and then solve for the y-coordinate.

Plugging this into the given formula:

Since it asks us to round, the maximum height would be 20 yards. To find how far the football travels in total, we need to set the equation equal to 0 and find the roots:

Then by the zero product property (or the no zero divisors rule), we have:

(this is the x value where the ball is kicked from)



So the ball travels 51 yards in total.
Answer:
X=20
Step-by-step explanation:
1. If he can place 12 eggs in each crate then are 12 eggs in one crate. (12 x 1 = 12)
2. If there are 8 rooms in a house, each with one bed then there are 8 beds in total. (8 x 1 = 8)
3. There are 20 ministers. ( 20 x 1 = 20)
4. If Sam earns $20 per hour, and he works one hour he will earn $20. (20 x 1 = 20)
Proportional is the relationship two numbers share. for instance, 3 : 6. for every three, there is six. for every one, there is two.
a table would be proportional if the top numbers and the bottom numbers corresponds, such as 1 on the top and 2 on the bottom. it would continue like 2 : 4, so on and so forth.
you can tell if fractions are proportional by using cross multiplication.
Y = -3x + 6/7
switch the x and y, then solve for y:


y = -x/3 + 2/7
