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.

A model train is traveling at a constant rate of 0.75 meter per second when Rebecca starts a stopwatch. Select the graph that represents the relationship between t, the amount of time since Rebecca started her stopwatch, and d, the total distance the train has traveled during that time.
Answer:
See Explanation
Step-by-step explanation:
Given
Rate = 0.75m/s
d = distance
t = time
Required
Select the graph that represents the given relationship
The option showing the graphs is missing. So, I'll answer the question from scratch.
We have that.
Rate = d/t (i.e. distance/time)
Substitute 0.75 for Rate
0.75 = d/t
Make d the subject
d = 0.75t
To plot the graph, we assume values for time (t)
Take t = 1
d = 0.75 * 1
d = 0.75
Take t = 6
d = 0.75 * 6
d = 4.50
So, we'll plot the graph at points
(1,0.75) and (6,4.50)

Helpppppp pleaseeeeee!!!!
Answer:
box 1, 4 and 5 are correct
Step-by-step explanation:
Box 1 is correct if you simplify the equation by multiplying both sides by 4. When you multiply the left side by 4 you end up with 56 + 8x since 4 times [tex]\frac{1}{4}[/tex] equals 1. The right side becomes 4 x 20 = 80. So 56 + 8X = 80. If you continue to solve for X, you first have to subtract 56 from both sides of the equal sign which looks like this: 56 - 56 + 8X = 80 - 56 which reduces down to 8X = 24. Dividing both sides by 8 then reduces that equation down to X = 3.
Box 4 is also correct. When you have an equation like [tex]\frac{1}{4}[/tex] (8x + 56), you have to multiple both numbers on the inside of the parentheses by the number on the outside of the parentheses. So the equation is ([tex]\frac{1}{4}[/tex] X 8x) + ([tex]\frac{1}{4}[/tex] X 56) which results in 2x + 14. The right side of the equal sign does not change so now you have
2x + 14 = 20. To get rid of the 14 on the left, you subtract 14 from both sides.
2x + 14 - 14 = 20 - 14. On the left, 14-14=0 so you end up with just 2x. On the right 20-14=6. So now you have the equation 2x = 6. If you continue to solve for x, you divide both sides of the equal sign by 2. This will give you x = 3. Same as what you get by solving for x in Box 1 above.
Box 5 is also correct. As you see above when you solve for X in both answers above, X = 3.

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:

23.984 round to the nearest tenth
Answer:
24
Step-by-step explanation:
9 is in the tenths place, and because 8 is in the hundredths, we need to move 9 up one number. However, that gives us 10. So we add 1 to 23 because 10 tenths is like 1 whole number.
