Based on these observations, the following statements are true for the given function: f(0) = 3, f(1) = 4, and f(2) = 5.
What is Functions?Functions are mathematical entities that take an input, perform some operation on it, and produce an output.
They are often represented using function notation, such as f(x), where f is the name of the function and x is the input.
Using the given table and function f(x) = x + COF, we can make the following observations:
The value of COF is not provided in the table, so we cannot determine the exact equation of the function.From the table, we can see that f(0) = 3. This means that when x = 0, the value of the function is 3. We can substitute this value into the equation to find that 0 + COF = 3, which implies that COF = 3.With COF = 3, the equation for the function becomes f(x) = x + 3.From the table, we can see that f(1) = 4 and f(2) = 5, which are consistent with the equation f(x) = x + 3.The value of f(-1) is not provided in the table, so we cannot determine its value.The value of f(4) is not provided in the table, so we cannot determine its value.Thus, the statements that are true for the given function: f(0) = 3, f(1) = 4, and f(2) = 5.

On a windy morning, a hot air balloon starts rising and flying away from the top of a hill. The altitude, h, in feet, of the balloon x hours after starting its ascent from the hill, can be modeled by the function:
Part B: There is a positive and negative x intercept for this function. What is the positive x-intercept?
Explain what this x-intercept represents in the given situation.
h(x)=-16x2+64x+80
Here the positive intercept should be considered as the -1 and 5.
Calculation of the positive intercept:Since X-Intercept shows the landing point i.e. bottom of the cliff since all x intercepts contains a y value of 0.
In this case it would be 0 feet.
So,
[tex]h(x)= -16x^2-16x+80x+80[/tex]
h(x)= -x(16x-16) +5(16x+16)
h(x)= (-x+5)(16x+16)
x intercepts = -1 and 5

like to have some leftovers. I've discovered that the proper ratio of turkey to people is 12 pounds of turkey for every 8 people. If 36 people are going to be eating, how many pounds of | turkey do I need to buy?
Answer:
A
Step-by-step explanation:
Took the test
There is a need for 58.5 pounds of turkey for 36 people.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
The proper ratio of turkey to people is 12 pounds of turkey for every 8 people.
Let the number of pounds would be x for 36 people
According to the given situation, we can write the ratio would be as:
12 pounds of turkey : 8 people = x pounds of turkey : 36 people
⇒ 12 / 8 = x / 36
Apply the cross-multiplication operation,
⇒ 8x = 13 × 36
Apply the multiplication operation,
⇒ 8x = 468
⇒ x = 468/8
Apply the division operation,
⇒ x = 58.5
Therefore, there is a need for 58.5 pounds of turkey for 36 people.

a rectangle has a length of 22 feet less than 6 times its width. if the area is of the rectangle is 868 square feet,find the length of the rectangle
Answer:
Length=62 feet
Step-by-step explanation:
L x W =area area= 868 L=6W-22
868=W x (6W-22)
868=6W^2-22W
reorder equation
6W^2-22W-868=0
Factor
(3W-42)(2W+20.7)=0
3W=42
W=14, then L=6(14)-22=62
Check:
62x14=868
The length of the rectangle is 62 feet.
Given,
A rectangle has a length of 22 feet less than 6 times its width.
The area of the rectangle is 868 square feet.
We need to find the length of the rectangle.
What is the area of a rectangle?It is given by:
A = Length x width
What is middle-term factorization?We have,
ax² + bx + c
a x c = p x q
The sum of p and q must be equal to b.
Find the length of the rectangle.
L = 6W - 22 ______(1)
Find the width of the rectangle.
Width = W ______(2)
Find the area of the rectangle.
A = L x W
868 square feet = L x W
From (1) and (2)
868 = (6W -22) x W
868 = 6W² - 22W
6W² - 22W - 868 = 0
Solve for W.
6W² - 22W - 868 = 0
Using middle-term factorization.
2( 3W² - 11W - 434 ) = 0
3W² - 11W - 434 = 0
3W² - ( 42 - 31 )W - 434 = 0
3W² - 42W + 31W - 434 = 0
3W ( W - 14 ) + 31 ( W - 14 ) = 0
3W + 31 = 0
3W = - 31
W = - 31 / 3 ( Can not be a negative)
W - 14 = 0
W = 14
Putting W = 14 in (1)
L = 6W - 22
L = 6 x 14 - 22
L = 84 - 22
L = 62
Thus the length of the rectangle is 62 feet.

Michael's High School is selling tickets to its spring musical. On the first day of ticket sales the school sold 1 adult ticket and 3 student tickets for a total of $38. The second day of sales, the school sold 5 adult tickets and 1 student ticket for a total of $78
Write a system of equations to represent the number of tickets sold each day
Determine the price of an adult ticket and a student ticket
Answer:
adult ticket price: $14
student ticket price: $8
Step-by-step explanation:
x = adult ticket
y = student ticket
system equations:
[tex]x + 3y = 38 \\ 5x + y = 78[/tex]
elimination method:[tex]x + 3y = 38 |multiple \: by \: 1\\ 5x + y = 78|multiple \: by \: 3 \\ \\ x + 3y = 38 \\ 15x + 3y = 234 \\ subract \: them: \\ - 14x = - 196[/tex]
substitute:[tex] - 14x = - 196 \\ - x = \frac{ - 196}{14} \\ - x = - 14 \\ x = 14[/tex]
find the y using substitution method:
x+3y=38
14+3y=38
3y=24
y=24/3
y=8

Explanation:
Let's go through the answer choices one at a time.
A) The AA postulate is only used for similar triangles, and not congruent triangles. We need information about at least one pair of sides. Using the angles only isn't enough. We can rule out choice A.B) The HL postulate only applies to right triangles. These triangles are acute triangles, so we can rule out choice B.C) This is the answer as we can rule out choice D, so this is the only thing left. Also, if we know that angle A = angle A'' and angle B = angle B'', then we could use the ASA theorem to prove the triangles congruent.D) This is not a valid congruence theorem. This is because we could have ambiguous cases that arise and lead to confusion. Also, it is possible that if we know two sides and a non-included angle, then a triangle may not be able to be formed. It will depend on the angle and side values. Therefore, we can rule out choice D.Brandi rolls a fair Six-sided Number cube flips a fair coin, and then rolls the number cube again. Which outcome is part of sample space?
Answer:
Options aren't given but explanation and answer is below:
Step-by-step explanation:
First action/trial - Rolling a fair dice (6-sided number cube)
Second action - Flipping a fair coin
Third action - Rolling a fair dice
In this experiment, all the equipment are fair. What this means is that there is no bias; every face of each equipment has an equal chance of emerging tops.
In your options, you should have three values per option.
The first would be the number resulting from the first throw of dice.
The second would be head or tail; which are the only two faces of a coin.
The third would be the number resulting from the second throw of dice.
So ONE of those options will be a part of the sample space, which is enlisted below:
Trial A: {1, 2, 3, 4, 5, 6}
Trial B: {Head, Tail}
Trial C: {1, 2, 3, 4, 5, 6}
* If there's an option like {9, Tail, 2} it will be wrong, because it has an element "9" which does not fall within the prescribed sample space.
* Also, if we follow the order in which Brandi conducted this experiment, an option like {Head, 6, 5} will be wrong, since the elements are wrongly placed.

Which equation best represents the line? (4 points)
Oy - 3x - 1
Oy - 3x + 1
Answer:
The equation best represents the line is:
y = 3x-1Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptTaking the two points
(0, -1)(1, 2)Determining the slope between the points (0, -1) and (1, 2)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:-1\right),\:\left(x_2,\:y_2\right)=\left(1,\:2\right)[/tex]
[tex]m=\frac{2-\left(-1\right)}{1-0}[/tex]
Refine
[tex]m=3[/tex]
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
As we are given the point (0, -1)
It means at x = 0, y = -1
Thus, the y-intercept b = -1
now substituting b = -1 and m = 3 in the slope-intercept form
y = mx+b
y = 3x + (-1)
y = 3x-1
Therefore, the equation best represents the line is:

A coach throws a football from a height of 4 feet with an initial velocity of 59 feet per second at an elevation angle of 45 degrees. Which parametric equation represents the path of the football
Answer:
[tex]x=(59cos 45\textdegree)t,y=4+(v_0sin45\textdegree)t-16t^2[/tex]
Step-by-step explanation:
From the question we are told that
Height [tex]h=4feet[/tex]
Initial velocity of[tex]v_0=59 feet/sec[/tex]
Angle [tex]\theta= 40\textdegree[/tex]
Generally the parametric equation for projectile motion is mathematically given by
[tex]x=(v_0cos\theta)t,y=y_0+(v_0sin\theta)t-16t^2[/tex]
Therefore
[tex]x=(59cos 45\textdegree)t,y=4+(v_0sin45\textdegree)t-16t^2[/tex]
