Problem 4
Like the three earlier problems, we'll place the kicker at the origin and have her kick to the right. The two roots in this case are x = 0 and x = 20 to represent when the ball is on the ground.
This leads to the factors x and x-20 and the equation 
We'll plug in (x,y) = (10,28) which is the vertex point. The 10 is the midpoint of 0 and 20 mentioned earlier.
Let's solve for 'a'.
This then leads us to:
The equation is in the form 
with 
The graph is below in blue.

Problem 5
The same set up applies as before.
This time we have the roots x = 0 and x = 100 to lead to the factors x and x-100. We have the equation 
We'll use the vertex point (50,12) to find 'a'.
Then we can find the standard form
The graph is below in red.
Explanation:
Say your # is 100, and 25% of that is 75.
133.3333333333333333333333333333333333(forever)% of it is 100.

Answer:
If Y equals 8, X is equal to 17.
If Y drops to 4, X is equal to 19.
Step-by-step explanation:
We know that the equation is 
and we want to find X when Y = 8. To do this we solve the equation for X.
17.4444 rounded to the nearest whole number is 17.
If Y drops to 4,
19.2222 rounded to the nearest whole number is 19.
2x-3y=-15
subtract 2x from each side
-3y = -2x-15
divide by -3
y = 2/3 x +5
this is in slope (2/3) intercept (5) form
Answer:
The measure of the angles are 55° and 35°
Step-by-step explanation:
Sum of two angles that are complement of each other are 90.
The angles are A and B, so we can write:
A + B = 90
Also,
The difference is 20. Let A be the greater of them, so we can write equation 2 as:
A - B = 20
Now, we add up both equations, eliminate B and solve for A first:
A + B = 90
A - B = 20
---------------
2A = 90 + 20
2A = 110
A = 110/2
A = 55
And now the measure of B:
A + B = 90
55 + B = 90
B = 90 - 55
B = 35
