Step-by-step explanation: (view attached screenshot)
(18, 0) is 18 units left, 0 units up. This make the point line up exactly on the x-axis
(0, 12) is 0 units left, and 12 units up. This will cause it to be in the line of y-axis.
(4.5, 10.6) both x and y values in the point are positive, this means that it's in the first quadrant
(-15, 21) x value is negative, y value is positive. This means that the point is in the second quadrant
[tex](-\frac{3}{4}, -\frac{4}{9})[/tex] both x and y values are negative. This means that the point is in the third quadrant.
(3, -7) x value is positive, y value is negative. This means that it's in the fourth quadrant.

Answers
Part A
The functions would be:
[tex]\begin{gathered} WG(x)=x+5 \\ LG(x)=3x+2 \end{gathered}[/tex]Part B
[tex]\begin{gathered} AG(x)=WG(x)\cdot LG(x) \\ \rightarrow AG(x)=(x+5)(3x+2) \\ \rightarrow AG(x)=3x^2+2x+15x+10 \\ \\ \Rightarrow AG(x)=3x^2+17x+10 \end{gathered}[/tex]Part C
Let's evaluate x = 7 in AG(x)
[tex]\begin{gathered} AG(7)=3(7^2)+17(7)+10 \\ \rightarrow AG(7)=276 \end{gathered}[/tex]Thereby, the area of the garden would be 276 square feet
Part D
The functions would be:
[tex]\begin{gathered} WB(x)=\frac{x}{2} \\ LB(x)=x+2 \end{gathered}[/tex]Part E
[tex]\begin{gathered} AB(x)=WB(x)\cdot LB(x) \\ \rightarrow AB(x)=(\frac{x}{2})(x+2) \\ \\ \Rightarrow AB(x)=\frac{x^2}{2}+x \end{gathered}[/tex]Part F
[tex]\begin{gathered} ATB(x)=x^2+AB(x) \\ \rightarrow ATB(x)=x^2+\frac{x^2}{2}+x \\ \\ \Rightarrow ATB(x)=\frac{3}{2}x^2+x \end{gathered}[/tex]Part G
[tex]\begin{gathered} AR(x)=AG(x)-ATB(x) \\ \rightarrow AR(x)=3x^2+17x+10-\frac{3}{2}x^2-x \\ \\ \Rightarrow AR(x)=\frac{3}{2}x^2+16x+10 \end{gathered}[/tex]Part H
We have a function for the area of the bell pepper patch in terms of x, the measurement of the lenght and width of the tomato patch. This is:
[tex]AB(x)=\frac{x^2}{2}+x[/tex]We know the value of this area. This way, we can solve the equation for x,
[tex]31.5=\frac{x^2}{2}+x\rightarrow63=x^2+2x\rightarrow x^2+2x-63=0[/tex]Using the cuadratic formula, and ignoring non-positive results, we'll get that
[tex]x=7[/tex]Now, plugging in this value in AR(x),
[tex]\begin{gathered} AR(7)=\frac{3}{2}(7^2)+16(7)+10 \\ \Rightarrow AR=195.5 \end{gathered}[/tex]This way, we can conclude that the remaining space in the garden after planting tomatoes and bell peppers is 195.5 square feet

a) The linear equation that models the price-sales relationship for toy is C(x) = -500x +5500
b) The forecast calls for 2250 sales at a $6.50 pricing.
Define slope.The ratio of the increase in elevation between two points to the run in elevation between those same two points is referred to as the slope.
A line's equation is represented by:
y = mx +b
, where
The slope, or m, represents the rate of change.
The value of y at x = 0 is represented by the y-intercept or b.
Item a:
In this issue:
Two points are (6, 2500) and (8, 1500).
The slope is calculated by dividing the change in y by the change in x, so:
m = [tex]\frac{1500-2500}{8-6}[/tex]
m = [tex]\frac{-1000}{2}[/tex]
m = -500
Thus,
y = -500x +b
Point (6,2500) indicates that, which we utilize to find b, is true when.
y = -500x +b
2500 = -500(6) + b
b = 5500
Thus
y = -500x + 5500
Item b:
When x = 6.5, sales are y, so:
y = -500(6.5) + 5500
y = 2250
The forecast calls for 2250 sales at a $6.50 pricing.

Marginal Average Cost Function C'(x) = 5.7
Step-by-step explanation:
The Marginal Average Cost is just the first differential of the Cost Function
[tex]\dfrac{d}{dx} C(x) = \dfrac{d}{dx}(161) + \dfrac{d}{dx}(5.7x)\\\\\\The first differential of a constant is 0 and the first differential of ax is a \\\\So ,\\\\\dfrac{d}{dx} C(x) = 0 + 5.7 = 5.7[/tex]
This means that as x increases by 1 unit, cost increases by 5.7 units. x presumably refers to the number of units produced
The Marginal Revenue can be found the same way
[tex]\dfrac{d}{dx} R(x) = \dfrac{d}{dx}6x - \dfrac{d}{dx}(0.08x^2)\\\\\dfrac{d}{dx}6x = 6\\\\\dfrac{d}{dx}(0.08x^2) = (2)(0.08)x[/tex]

Answer: Choice C) 9/11
========================================================
Explanation:
Finding the average rate of change over the interval 2 ≤ x ≤ 13 is the exact same as finding the slope of the line through the points (2,1) and (13,10)
[tex](x_1,y_1) = (2,1) \text{ and } (x_2,y_2) = (13,10)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{10 - 1}{13 - 2}\\\\m = \frac{9}{11}\\\\[/tex]
The slope of the line through (2,1) and (13,10) is 9/11 which is also the rate of change we're looking for.

An is greater than b when a > b. These two constitute strict inequality.
A must be less than or equal to b if a and b are divided.
An is greater than b if a and b are equal.

then 2x - 5
= 2(1)-5
= -3 which is smaller than 1
It means x at least need to be equal to 6 or greater than 6 to Pythagoras theorem to be possible

How tall will the candles be when they first burn down to the same height?
Answers
The height of the candles when they would be the same height is 10cm.
What is the height when the two candles would be the same?The first step is to determine how much of each candle is left after one hour.
Candle left after c hours = height of the candle - rate at which the candle burns per hour x c
Rate at which the candle burns per hour = 5/6
15 - 5/6c
Candle left after c hours = 25 - 2 1/2c
When the two candles are of the same height, the two above equations would be equal
15 - 5/6c = 25 - 2 1/2c
Combine similar terms: 25 - 15 = 2 1/2 - 5/6c
Add similar terms: 10 = 1 2/3 c
Divide both sides by 3/5: 10 = 5/3c
c = 10 x 3 / 5
c = 6 hours
Height in 3 hours = 15 - 5/6(6) = 15 - 5 = 10cm

The fractional part that Alison is still missing is 3/10.
What is a fraction?A fraction is a part of an absolute value or number.
Fractions are always less than one.
Fractions are denoted by a numerator (upper part or dividend) less than the denominator (the lower portion known as the divisor).
There are proper and improper fractions.
The fraction found under the coffee table = 3/10
The fraction found under the couch = 4/10
The total fractional part found so far = 7/10 (3/10 + 4/10)

Which of the following could be the ratio between the lengths of the two legsof a 30-60-90 triangle?Check all that apply.A. 2:13OB. 5:15C. 2:15OD. 1 : 15E. 1 : 2UO F. 5:3
Answers
Let a, b, c be the length of sides of the triangle lying opposite to angles measuring 30, 60 and 90 degrees, respectively.
Applying the sine law,
[tex]\frac{a}{\sin30}=\frac{b}{\sin60}=\frac{c}{\sin 90}[/tex]Which characteristic of the line that passes through the points (6,10) and (12,2)..
Answers
SOLUTION:
Let us find the slope of the line:
[tex]m\text{ = }\frac{y_2-y_1}{x_2-x_1}[/tex]Where x1 = 6, x2 = 12, y1 = 10 and y2 = 2
[tex]\begin{gathered} m\text{ = }\frac{2-10}{12-6} \\ m\text{ = }\frac{-8}{6}\text{ = -}\frac{4}{3} \\ \\ \end{gathered}[/tex]The slope of the given line is -4/3

The income from the sales of potatoes in 2021 is equal to €510.
How to calculate the income from potatoes?From the information provided, we can logically deduce that the total income (revenue) that was generated from the sales of the four (4) vegetables in 2021 is equal to 2040 Euros (€).
Note: Each interval of the bar chart on the y-coordinate represents €40.
Assuming the pie chart was drawn to scale, we can reasonably infer and logically deduce that each of its sector represent 25%. This ultimately implies that, the income for the sales of potatoes in 2021 is 0.25 of the total income (revenue) that was generated from the sales of the four (4) vegetables in 2021.
Mathematically, the income for the sales of potatoes in 2021 can be calculated as follows:
Income from potatoes = 25/100 × 2040
Income from potatoes = 0.25 × 2040
Income from potatoes = €510.
