3. Patrick kicks a soccer ball from the ground into the air. When the ball is a horizontal distance of 12 feet from
him, it is 14 feet above the ground. When the ball is 32 feet from him, it is 7 feet above the ground.
Use quadratic regression on a graphing calculator to write a function for the height of the ball in terms of
its horizontal distance Round to the nearest thousandth (
Answer:
The function for the height of the ball in terms of its horizontal distance is
[tex]y = -\frac{91}{1920}\cdot x^{2}+\frac{833}{480}\cdot x[/tex]
Step-by-step explanation:
From Physics, we know that ball describes a parabolic motion, in which trajectory is described by the following second-order polynomial (quadratic function):
[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (Eq. 1)
Where:
[tex]x[/tex] - Horizontal distance, measured in feet.
[tex]y[/tex] - Vertical distance above the ground, measured in feet.
[tex]a[/tex] - Second order coefficient, measured in [tex]\frac{1}{ft}[/tex].
[tex]b[/tex] - First order coefficient, dimensionless.
[tex]c[/tex] - Zero order coefficient, measured in feet.
We can obtain the second-order polynomial associated with the soccer ball by knowing three distinct points and solving the resulting system of linear equations. If we know that [tex](x_{1},y_{1}) =(0\,ft, 0\,ft)[/tex], [tex](x_{2},y_{2})=(12\,ft, 14\,ft)[/tex] and [tex](x_{3},y_{3})=(32\,ft, 7\,ft)[/tex], then the system of linear equations is:
[tex]c = 0[/tex]
[tex]144\cdot a+12\cdot b +c = 14[/tex]
[tex]1024\cdot a +32\cdot b + c = 7[/tex]
The solution of this linear system is:
[tex]a = -\frac{91}{1920}[/tex], [tex]b = \frac{833}{480}[/tex], [tex]c = 0[/tex]
Therefore, the function for the height of the ball in terms of its horizontal distance is
[tex]y = -\frac{91}{1920}\cdot x^{2}+\frac{833}{480}\cdot x[/tex]
In addition, we present a graphic of the given function as attachment.

The same garden shop sells mulch according to the equation y = 20x, where y represents the cost in dollars, and x represents the number of cubic yards of mulch. Which statement is true of the cost of topsoil and mulch?
Answer:
20 = cost per mulch of cubic yards sold
Step-by-step explanation:
Given:
y = 20x
Where,
y = the total cost in dollars
x = the number of cubic yards of mulch
20 = cost per mulch of cubic yards sold
The only untrue statement is that the cost of topsoil and mulch is 20

Answer:
Answer: The table is proportional.
Step-by-step explanation: You would do 21/6 to get 3.5. Then 28/8 to get 3.5. After 35/10 to get 3.5. Finally 49/14 to get 3.5. If each answer (3.5) is the same than it is proportional.
Answer: The table is proportional.

Some friends played a board game. During the game, one unlucky player had to move back 5 spaces 8 turns in a row. Find a number to represent that player's movements for those 8 turns.
Answer:
Total move back spaces = 40
or
Total moves = -40
Step-by-step explanation:
Given:
Move back spaces = 5
Number of total turn = 8
Find:
Total move back spaces
Computation:
Total move back spaces = 5 x 8
Total move back spaces = 40
or
Total moves = -40
Explain how to convert an equation from slope-point from to slope-intercept fom.
Step-by-step explanation:
When you compare the two ways of writing a line, you might notice that there are some similarities. Both retain a y variable, an x variable and the slope of the line. So all you really need to get from point-slope form to slope-intercept form is a little algebraic manipulation. Consider the example given of a line in point-slope form: y + 5 = 3(x – 2).
Distribute x- Use the distributive property to simplify the right side of the equation:
Isolate the y Variable- Subtract 5 from both sides of the equation to isolate the y variable, which gives you the equation in point-slope form:

Find the measure of angle AEF in the figure below enter only the number
Answer:
60
Step-by-step explanation:
The middle is a straight angle, which is 180 degrees, and FEB is 120 degrees. 180 - 120 is 60
The measure of the angle AEF will be equal to 60°.
What is coordinate geometry?A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
The supplementary angles are the angles having the sum of the angles as 180 degrees.
The middle is a straight angle, which is 180 degrees, and FEB is 120 degrees.
The measure of the angle AEF is,
AEF = 180 - 120
AEF = 60°
Therefore, the measure of the angle AEF will be equal to 60°.
