Step-by-step explanation:
A local pizza shop has a membership program for frequent buyers. The membership costs $20 per month and members get a discounted price of $1.25 per slice of pizza. Chee purchased a membership to this pizza shop. How much would Chee have to pay the pizza shop if she bought 12 slices of pizza this month? What would be the monthly cost for x slices of pizza?
Answer:
$35 for 12 slices
Monthly cost for x slices of pizza = 20 + 1.25x
Step-by-step explanation:
Monthly Membership cost = $20
Discounted cost per slice of pizza = $1.25
Discounted total cost for 12 slices = $1.25 x 12 = $15
Total cost = 20 + 15 = $35 this momth
For x slices of pizza, monthly cost = 20 + 1.25x
A figure is fully contained in Quadrant Il.
Looking at the coordinate plane below, which letter represents this quadrant?
From the division of quadrants in the xy-plane, it is found that letter K represents the second quadrant.
What are the signals of the coordinates in each quadrant?There are four quadrants of points (x,y), and their signals are given as follows:
Quadrant 1: x is positive(left of y-axis) and y is positive(above the x-axis).Quadrant 2: x is negative(right of y-axis) and y is positive(above the x-axis).Quadrant 3: x is negative(right of y-axis) and y is negative(below the x-axis).Quadrant 4: x is positive(left of y-axis) and y is negative(below the x-axis).In this problem, we want Quadrant 2, in which:

the coordinate of X is at 8 units of P and at 4 units to the left of Q
So the coordinate of X is: -5 + 8 = 3
How to find the coordinates of point x?
We know that point X is between points P and Q, in such a way that the ratio between the lengths of the segments PX and XQ is 2:1
First, we can length of the segment PQ is equal to the difference between their coordinates, so we get:
L = 7 - (-5) = 12
Then the length of segment PQ is 12 units, if we divide that in 3 we will get:
12/3 = 4 units.
So the segment PQ can be divided into 3 segments of 4 units each.
If the ratio PX to XQ is 2:1
Then the segment PQ must be divided into 3 parts, such that PX takes two of these parts and XQ is the remaining one.
Then the coordinate of X is at 8 units of P and at 4 units to the left of Q
So the coordinate of X is: -5 + 8 = 3

he cost in dollars of making x items is given by the function C(x) = 10x + 500.
a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.
b. What is the cost of making 25 items?
c. Suppose the maximum cost allowed is $1500. What are the domain and range of the cost function, C(x)?
We get the fixed cost as $ 150, cost of 25 items as $ 750, range as [0, 1500] and the domain as [0,150].
We are given the cost function:
C(x) = 10x + 500.
Fixed cost is when x = 0
C(0) = Fixed cost = 10 ( 0 ) + 500
Fixed cost = $ 500
Cost of making 25 products is x = 25
C(25) = 10 (25) + 500
C(25) = 250 + 500 = $ 750
Maximum cost allowed = $ 1500
Function becomes:
10x + 500 ≤ 1500
x + 50 ≤ 150
x ≤ 150 - 50
x ≤ 100
Range = [0, 1500]
Domain = [0, 150]
Therefore, we get the fixed cost as $ 150, cost of 25 items as $ 750, range as [0, 1500] and the domain as [0,150].

How can you measure the way one variable changes in relation to another?
Solution:
The word correlation is used in everyday life to denote some form of association. We might say that we have noticed a correlation between foggy days and attacks of wheeziness. However, in statistical terms, we use correlation to denote the association between two quantitative variables. We also assume that the association is linear, that one variable increases or decreases a fixed amount for a unit increase or decrease in the other. The other technique that is often used in these circumstances is regression, which involves estimating the best straight line to summarise the association.
Correlation coefficient
The degree of association is measured by a correlation coefficient, denoted by r. It is sometimes called Pearson’s correlation coefficient after its originator and is a measure of linear association. If a curved line is needed to express the relationship, other and more complicated measures of the correlation must be used.
The correlation coefficient is measured on a scale that varies from + 1 through 0 to – 1. Complete correlation between two variables is expressed by either + 1 or -1. When one variable increases as the other increases the correlation is positive; when one decreases as the other increases it is negative. The complete absence of correlation is represented by 0.

Two angles are supplementary is the measure of one angle is 65.3 degrees what is the measure of the
other angle? Answer to the first decimal place, ie 79.5
The measure of the other angle is 114.7.
Given that the angles are supplementary,
Let the other angle be 'x'.
x + 65.3 = 180 degree
x = 114.7
hence, The other angle is 114.7 degrees.
The term "supplementary angles" refers to a pair of angles that always add up to 180°. These two perspectives are known as supplements. The term "supplementary" is derived from the Latin words "supply" and "plere," where "supply" means "supply" and "plere" means "fill." As a result, "supplementary" means "something that is supplied to complete a thing."
If two angles add up to 180 degrees, they are said to be supplementary angles. When supplementary angles are combined, they form a straight angle (180 degrees). In other words, if Angle 1 + Angle 2 = 180°, angles 1 and 2 are supplementary. Angles 1 and 2 are referred to as "supplements" in this case.

Use the triangle below to find the measure of angle G.
Answer:
59.3° (nearest tenth)
Step-by-step explanation:
Cosine Rule (for finding angles)
[tex]\boxed{\sf \cos(C)=\dfrac{a^2+b^2-c^2}{2ab}}[/tex]
where:
C = anglea and b = sides adjacent the anglec = side opposite the angleFrom inspection of the given triangle:
C = angle Ga = side GI = 6b = side GH = 15c = side HI = 13Substitute the values into the formula and solve for G:
[tex]\implies \sf \cos(G)=\dfrac{6^2+15^2-13^2}{2(6)(15)}[/tex]
[tex]\implies \sf \cos(G)=\dfrac{36+225-169}{180}[/tex]
[tex]\implies \sf \cos(G)=\dfrac{92}{180}[/tex]
[tex]\implies \sf G=\cos^{-1} \left(\dfrac{92}{180}\right)[/tex]
[tex]\implies \sf G=59.26213133...^{\circ}[/tex]
Therefore, the measure of angle G is 59.3° (nearest tenth).

a) Boris can expect to gain money. He can expect to win ___ dollars per draw
b) Boris can except to lose money. He can except to lose ___ dollars per draw.
c) Boris can except to break even( neither gain or lose money)
Boris can expect to break even ( neither gain or lose money) is the answer.
The probability of a number is calculated by dividing Favorable outcome by Total outcome.
The probability of a number between 1 to 10 = Favorable outcome/Total outcome
Favorable outcome =1 (any one number )
Total outcome = 10
Here p(x) is equal to 1 divided by 10
P(X)= 1/10= 0.1
The table gives us the Amount when we multiple X to P(X),
Expected value = (XiP(Xi))
When we substitute the value we get,
=(10.1)+(-50.1)+(30.1)+(-50.1)+(50.1)+(-50.1)+(70.1)+(-50.1)+(90.1)+(-50.1)
=0
So we will get zero after substituting the value.
Hence, option C Bories can Expect to break even (Neither gain or lose money) is the correct answer.

From the above values in the table, when x = 0, y = f(0) = 1
Therefore;
f(0) = 1(b) y = 12 - 2•x²
Taking the function, f(x) = y, we have;
At x = 0, y = f(0) = 12 - 2 × 0² = 12
Therefore;
f(0) = 12(c) A graph of a parabola passing through the points (-1, 3), (2, -6), (5, 3)

FIND VALUE
A) tan 30° + cot 30° + sin 60°
Answer: [tex]\frac{4\sqrt{3} }{3} +\frac{1}{2}[/tex]
Step-by-step explanation:
You can either do this manually or use your calculator. Using your calculator, make sure that your calculator is in degree mode, then enter tan(30) + (1/tan(30)) + sin(60). [1/tan(30) is equal to cot(30) because tangent and cotangent are inverse functions].
Manually, use the unit circle. Tangent is sine over cosine. Sine of 30 degrees is 1/2. Cosine of 30 degrees is [tex]\sqrt{3} /2[/tex]. 1/2 divided by [tex]\sqrt{3}/2[/tex] is [tex]\sqrt{3}/3[/tex]. Cotangent is 1/tangent so take 1/[tex]\sqrt{3}/3[/tex] which is [tex]\sqrt{3}[/tex]. Then we already said that sine of 30 degrees is 1/2, so add them all together.
[tex]\sqrt{3}/3+\sqrt{3}+\frac{1}{2}[/tex] which is equal to [tex]\frac{4\sqrt{3} }{3} +\frac{1}{2}[/tex] or approximately 2.8094.
