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 (
Answers
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.

Answers
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°.

Explain how to convert an equation from slope-point from to slope-intercept fom.
Answers
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:
slope = -2,through (3,-5)

2. To find the perpendicular line, the slope would be -1/m. So the slope of the equation would be -1/2x so the form would be y=-1/2x+b. If we put the points in here, it would be 3=-1/2(-5)+b 3=2.5+b b=1/2 So the equation would be y=-1/2x+1/2
