What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
As per the given,
The fee for a food booth is $200 plus $5 per day.
Total cost for d days will be = 200 + 5d
The fee for a game booth is $95 plus $10 per day.
Total cost for d days will be = 95 + 10d
Total cost for d days = (200 + 5d) + (95 + 10d)
⇒ 200 + 95 + 5d + 10d
⇒ 295 + 15d
Hence "The expression that represents the total paid by the company is 295 + 15d".

Payton leaves to go on an 8585 minute bike ride at 3{:}27\text{ p.M.}3:27 p.M. Payton's family eats dinner at 5{:}45\text{ p.M.}5:45 p.M. How much time will Payton have between finishing her bike ride and eating dinner?
Answer:
53 minutes.
Step-by-step explanation:
We have been given that Payton leaves to go on an 85 minute bike ride at 3:27 pm.
Let us find when Payton will finish biking by 85 minutes after 3:27 pm.
Since 85 minutes equals to 1 hour and 25 minutes. 1 hour after 3:27 pm will be 4:27 pm. Now let us add 25 minutes to 4:27 pm.
So Payton will finish biking at 4:(27+25) pm= 4:52 pm.
Payton's family eats dinner at 5:45 pm. Now let us find remaining time between dinner and 4:52 pm.
[tex]\text{Minutes between dinner and finishing bike ride}=5:45 pm- 4:52 pm[/tex]
[tex]\text{Minutes between dinner and finishing bike ride}=53[/tex]
Therefore, Payton have 53 minutes between finishing her bike ride and eating dinner.

Given:
b1 = 17 ft
b2 = 20 ft
h = 13 ft
r = 17/2 = 8.5 ft
Area of the Semi-circle = 1/2 π r²
= 1/2 (22/7) (8.5²)
= (11/7) (72.25)
= 113.535 ft²
Area of the trapezium = (h) (b1 + b2) / 2
= (13)(17 + 20)/2
= 240.5 ft²
Total area of the amphitheater stage = Area of Semi-circle + Area of the trazezium = 113.535 + 240.5 = 354.035 ft²

Millie needs the average height of the plants she is buying to be at least 73 inches. She has selected three plants that are 70, 71 and 72 inches tall. Write and solve an inequality that Millie could use to determine the possible heights of her fourth plant
Answer:
[tex]\frac{70+71+72+x}{4}\geq 73[/tex]
[tex]x\geq 79[/tex]
Step-by-step explanation:
Let x be the height of 4th plant purchased by Millie.
We have been given that Millie needs the average height of the plants she is buying to be at least 73 inches. She has selected three plants that are 70, 71 and 72 inches tall.
So the average of 4 plants purchased by Millie will be: [tex]\frac{70+71+72+x}{4}[/tex]
We can represent this information in an inequality as: [tex]\frac{70+71+72+x}{4}\geq 73[/tex]
Therefore, our desired inequality will be [tex]\frac{70+71+72+x}{4}\geq 73[/tex].
Now let us solve our inequality by multiplying both sides of inequality by 4.
[tex]4*\frac{70+71+72+x}{4}\geq 4*73[/tex]
[tex]70+71+72+x\geq 292[/tex]
[tex]213+x\geq 292[/tex]
[tex]x\geq 292-213[/tex]
[tex]x\geq 79[/tex]
Therefore, the height of 4th plant purchased by Millie must be at least 79 inches.

If A, B, and C are the interior angles of triangle ABC, prove that
4 sinA sinB sinC = sin2A + sin2B + sin2C
NOTES:
1)⇒ A + B + C = 180°
A + B + C = π
A + B = π - C
2)⇒⇒ sin (A + B) = sin (π - C)
= (sin π)(cos C) - (sin C)(cos π)
= (0)(cos C) - (sin C)(-1)
= 0 - (-sin C)
= sin C
3)⇒⇒⇒cos (A + B) = cos (π - c)
= (cos π)(cos C) + (sin π)(sin C)
= (-1)(cos C) + (0)(sin C)
= - cos C
4)⇒⇒⇒⇒ sin 2A + sin 2B = 2 sin (A + B) cos (A - B)
PROOF (from left side):
sin 2A + sin 2B + sin 2C = 4 sin A sin B sin C
2 sin (A + B) cos (A - B) + sin 2C refer to NOTE 4
2 sin (A + B) cos (A - B) + 2 sin C cos C double angle formula
2 sin C cos (A - B) + 2 sin C cos C refer to NOTE 2

Triangle ABC has vertices at A(1, 2) B(4, 6) and C(4, 2) in the coordinate plane. The triangle will be reflected over the x-axis and then rotated 180 degrees about the origin to form ABC. What are the vertices of A'B'C'?
Answer:
The vertices of A'B'C are A'(-1,2), B'(-4,6) and C'(-4,2).
Step-by-step explanation:
Triangle ABC has vertices at A(1, 2) B(4, 6) and C(4, 2).
If a figure reflected over x-axis, then
[tex](x,y)\rightarrow (x,-y)[/tex]
Therefore the vertices of triangle ABC after reflection over x-axis are:
[tex]A(1,2)\rightarrow A'(1,-2)[/tex]
[tex]B(4,6)\rightarrow B'(4,-6)[/tex]
[tex]C(4,2)\rightarrow C'(4,-2)[/tex]
Rotation 180 degrees about the origin is defined as
[tex](x,y)\rightarrow (-x,-y)[/tex]
Therefore the vertices of triangle ABC after reflection over x-axis followed by rotated 180 degrees about the origin are:
[tex]A(1,-2)\rightarrow A'(-1,2)[/tex]
[tex]B(4,-6)\rightarrow B'(-4,6)[/tex]
[tex]C(4,-2)\rightarrow C'(-4,2)[/tex]
Therefore the vertices of A'B'C are A'(-1,2), B'(-4,6) and C'(-4,2).

Points A and B are 200 mi apart. A cyclist started from point A and a motorcyclist started from point B, moving towards each other.The speed of the cyclist was 17 mph, the speed of motorcyclist was 83 mph. At what distance from point A will they meet?
Answer:
34 miles is the distance from point A will they meet.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
Given the statement:
Distance between point A and B (i.e AB) = 200 mi.
Let the cyclist speed be c, and motor- speed be m;
then;
c = 17 mph and m=83 mph
Let they meet at distance x miles from a point A.
By definition of proportion, we have;
[tex]\frac{x}{17} =\frac{200-x}{83}[/tex]
By cross multiply;
[tex]83x = 17(200-x)[/tex]
Using distributive property, [tex]a\cdot(b+c) =a\cdot b+ a\cdot c[/tex]
[tex]83x = 3400 - 17x[/tex]
Add 17x both sides we get;
[tex]83x+ 17x= 3400 - 17x +17x[/tex]
Simplify:
100x = 3400
Divide by 100 on both sides we get;
x = 34 miles
Therefore, the distance from point A will they meet is, 34 miles.

In your lab, a substance's temperature has been observed to follow the function f(x) = (x − 1)3 + 9. The point at which the function changes curvature from concave down to concave up is where the substance changes from a solid to a liquid. What is the point where this function changes curvature from concave down to concave up?
Hint: The point is labeled in the picture.
Answer:
The point of change is the point (1,9)
Step-by-step explanation:
The first derivative of the function equated to zero will give you the point where the function changes.
Therefore, to solve this problem find the first derivative of f (x)
[tex]f '(x) = 3*3(x-1)^{3-1}\\\\f '(x) = 9(x-1)^2[/tex]
Now we equate the derivative to 0.
[tex]9 (x-1)^ 2 = 0\\\\x = 1[/tex]
Then the derivative of the function is equal to 0 when x = 1. This means that the concavity of the function changes in x = 1.
When [tex]x = 1, y = 3(1-1) ^ 3 +9\\\\x =1, y = 9.[/tex]
Then the point of change is the point (1,9)
Answer:
The point of inflection is (1,9)
Step-by-step explanation:
We have following given function
[tex]f(x)=(x-1)^{3} +9[/tex]
The point at which the function changes its curvature is defined by the point of inflection.
To find point of inflection we set 2nd derivative to 0
[tex]f''(x)= 0[/tex]
The first derivative is given by
[tex]f'(x)= \frac{d}{dx} [(x-1)^{3} +9][/tex]
[tex]f'(x)= 3(x-1)^{2}[/tex] ( using chain rule and derivative of constant is 0)
now again we take 2nd derivative
[tex]f''(x)=3(2(x-1))[/tex]
[tex]f''(x)=6(x-1)[/tex]
now we equate 2nd derivative to 0
[tex]6(x-1)=0\\x-1=0\\x=1[/tex]
hence point of inflection is at x=1
now we find y coordinate of point of inflection by plugging x=1 in f(x)
[tex]y=f(1)=(1-1)^{3} +9 =9[/tex]
Hence the point of inflection is (1,9)

This is a cubic function. The end behavior of the graph will increase to the right and decrease to the left.
This is a cubic function. The end behavior of the graph will decrease to the right and increase to the left.
Answer: D
Step-by-step explanation:
End behavior is determined by two factor:
1. Coefficient - determines right side:
If the leading coefficient is POSITIVE, then right side goes to +∞If the leading coefficient is NEGATIVE, then right side goes to -∞2. Degree - determines left side:
If degree is EVEN, then left side is SAME as right sideIf degree is ODD, then left side is OPPOSITE of right side******************************************************************************************
-x³ + 2
Leading coefficient is NEGATIVE, so right side goes to -∞ (decreases)
Degree is ODD, so left side is opposite of right side → goes to +∞ (increases)

We are given that revenue of Tacos is given by the mathematical expression [tex]-7x^{2}+32x+240[/tex].
(A) The constant term in this revenue function is 240 and it represents the revenue when price per Taco is $4. That is, 240 dollars is the revenue without making any incremental increase in the price.
(B) Let us factor the given revenue expression.
[tex]-7x^{2}+32x+240=-7x^{2}+60x-28x+240\\-7x^{2}+32x+240=x(-7x+60)+4(-7x+60)\\-7x^{2}+32x+240=(-7x+60)(x+4)\\[/tex]
Therefore, correct option for part (B) is the third option.
(C) The factor (-7x+60) represents the number of Tacos sold per day after increasing the price x times. Factor (4+x) represents the new price after making x increments of 1 dollar.
(D) Writing the polynomial in factored form gives us the expression for new price as well as the expression for number of Tacos sold per day after making x increments of 1 dollar to the price.
(E) The table is attached.
Since revenue is maximum when price is 6 dollars. Therefore, optimal price is 6 dollars.

Given a standard deck of playing cards, what is the probability of randomly selecting a card that is either red or a face card or both? (a standard deck of playing cards has 52 cards, divided equally between red cards and black cards. there are twelve face cards among these 52, which are also divided equally between red cards and black cards. no card may be both red and black.)
Answer: [tex]\bold{\dfrac{8}{13}}[/tex]
Step-by-step explanation:
Red or Face - duplicates (both red & face)
[tex]\dfrac{26}{52}[/tex] + [tex]\dfrac{12}{52}[/tex] - [tex]\dfrac{6}{52}[/tex]
= [tex]\dfrac{32}{52}[/tex]
= [tex]\dfrac{8}{13}[/tex] simplified
Final answer:
The probability of selecting a red or face card from a standard deck of cards is 8/13. This outcome is more likely than selecting a heart suit face card specifically, which has a probability of 3/52.
Explanation:
The problem can be solved by understanding that the deck has 26 red cards (hearts and diamonds) and 12 face cards (jacks, queens, and kings), with 6 face cards being red. The total number of unique choices that are either red cards or face cards is the number of red cards plus the number of black face cards. This avoids double-counting red face cards.
There are 26 red cards, but we need to exclude the 6 red face cards already counted, and add the 6 black face cards (from clubs and spades), giving us 26 + 6 = 32 unique cards that are either red or face cards. The probability, P, is then 32/52, which simplifies to 8/13.
To compare, the probability of drawing specifically a heart suit face card is 3/52 as there are only 3 face cards (jack, queen, and king) in the heart suit. Comparing probabilities, 8/13 is greater than 3/52, so it is more likely to draw a red or face card than a heart suit face card.
What is an equation of the line that passes through the points (7,−6) and (3,−6)?
Answer:
The equation of this line would be y = -6
Step-by-step explanation:
In order to find this, we must first find the slope. For that we use the two points and the slope equation.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-6 - -6)/(7 - 3)
m = 0/4
m = 0
Given that slope, we can use it along with a point in point slope form. From there we can solve for y and get the equation.
y - y1 = m(x - x1)
y + 6 = 0(x - 7)
y + 6 = 0
y = -6
Final answer:
To find the equation of a line passing through given points, calculate the slope, use the point-slope formula, and simplify to obtain the final equation. In this case, the line passing through (7,-6) and (3,-6) results in the equation y = -6.
Explanation:
To find the equation of the line passing through the points (7,-6) and (3,-6):
Calculate the slope (m) using the formula: m = (y₂ - y₁) / (x₂ - x₁)
Substitute one of the points and the slope into the point-slope formula: y - y₁ = m(x - x₁)
Simplify the equation to get the final answer: y = mx + b
The equation of the line passing through those two points is y = -6.
