During a job interview, Pam Thompson is offered a salary of $32,000. The company gives annual raises a 4%. What will be Pam’s salary during her fifth year on the job? (Round time value factor to three decimal places and final answer to the nearest whole number.)
Answers
We will have the following:
First, we construct the equation that describes the scenario:
[tex]P(x)=32000(1+0.04)^x[/tex]Now, we will determine her salary at the 5th year at her job:
[tex]P(x)=32000(1+0.04)^5\Rightarrow P(5)=38932.89288[/tex][tex]\Rightarrow P(5)\approx38932.893[/tex]So, her salary after 5 years would be approximately $38933.

Answers
First item:
When a relation is presented as a set of ordered pairs (a,b) its domain is given by all the different values that appear in the first coordinate of the pairs. Analogously its range is given by all the different values that appear in the second coordinate. For example, if we have the following relation:
[tex]\mleft\lbrace(1,2\mright),(2,3),(2,4)\}[/tex]There are only two different values in the first coordinate of the pairs: 1 and 2. Then its domain is {1,2}.
There are three different values in the second coordinate of the pairs: 2, 3 and 4. Then its range is {2,3,4}.
Second item:
When the relation is presented in a mapping diagram we have something like this:
Each ellipse represents a set. The set from which the arrows come from is the domain and that at which the arrows arrive is the range. So for the relation shown in the picture its domain is {a,b,c,d} and its range is {x,y,z}
Third item:
When the relation is presented as a graph in a grid the domain will be given for all the values in the horizontal axis for which there's a corresponding value in the graph. If you draw a vertical line that passes through a value A in the horizontal axis you can find two cases:
- The line meets the graph at least once. Then A is part of the domain.
- The line never meets the graph. Then A is not part of the domain.
Something very similar happens with the range. The values that are part of the range are values in the vertical axis for which there's at least one corresponding value in the graph. If you draw a horizontal line that passes through a value B in the vertical axis you have:
- The line meets the graph at least once. Then B is part of the range.
- The line never meets the graph. Then B is not part of the range.

The value of x for the given triangle is 2√5 units.
According to the question,
We have the following information:
We have two triangles joint together whose sides are given.
Now, we will use the Pythagoras theorem to find the value of x.
Let's denote the hypotenuse of the triangles with h, perpendicular with p and base with b.
First, we will use it in triangle other than the side x.
[tex]h^{2} =p^{2} +b^{2}[/tex]
[tex]p^{2} =9^{2} -6^{2}[/tex]
[tex]p^{2} =81-36[/tex]
[tex]p^{2} = 45[/tex]
p = √45
p = 3√5 units
Now, the perpendicular of this triangle will be the hypotenuse of another triangle.
[tex]h^{2} =p^{2} +b^{2}[/tex]
[tex]b^{2} =(3\sqrt{5}) ^{2} - 5^{2}[/tex]
[tex]b^{2} = 45-25[/tex]
[tex]b^{2} = 20[/tex]
b = 2√5 units
Hence, the value of x is 2√5 units.

David wants to make profit of more than $300 but he only has $110 to spend on costs ahead of time. Create a total profit and a cost equation to model the situation with x = # of chicken legs and y = # cups of tenders.
Answers
SOLUTION
From the question,
Chicken legs cost $1, but the selling price is $4
Chicken tender cost $2 per cup, but the selling price is $8
Now, a festival costs $60 and David has only $110 to spend.
Also number of chicken legs sold is represented as x and
number of chicken tenders sold is represented as y.
Hence the cost equation becomes
[tex]\begin{gathered} x\times1\text{ dollar for chicken legs + y}\times2\text{ dollars for chicken tender + 60 }\leq110 \\ x+2y+60\leq110 \end{gathered}[/tex]Note that profit = sales - cost
So we have to subtract the cost from the sales.
Now, David wants to make sales more than $300.
Hence the sales equation becomes
[tex]\begin{gathered} x\times4\text{ dollars for chicken legs + y}\times8\text{ }\times\text{dollars for chicken tender }\ge300 \\ 4x+8y\ge300 \end{gathered}[/tex]So, we will subtract the cost equation from the sales equation to get the profit equation. This becomes
[tex]\begin{gathered} 4x+8y-(x+2y+60)\ge300 \\ 4x+8y-x-2y-60\ge300 \\ 4x-x+8y-2y\ge300+60 \\ 3x+6y\ge360 \end{gathered}[/tex]Hence, the cost and profit equation is
[tex]\begin{gathered} 60+x+2y\leq110 \\ 3x+6y\ge360 \end{gathered}[/tex]But what we have as a correct choice in the answers is the cost and sales equation, which is

How do you turn 2x+3y=12 into slope intercept form?
Answers
Answer:
y = -2x/3 + 4
Explanation:
The equation of a line in slope-intercept form is expressed as y = mx+c
Given the equation 2x+3y=12, you will have to make y the subject of the formula as shown:
Given
2x+3y=12
3y = 12 - 2x
3y = -2x + 12
Divide through by 3
3y/3 = -2x/3 + 12/3
y = -2x/3 + 4
Hence the expression in slope intercept form is y = -2x/3 + 4

So the next number must be 7 multiplied by double of 8 which is 16:
[tex]7\times16=112[/tex]Another way to see this sequence is that each number is twice the previous number:
14 is twice 7
28 is twice 14
56 is twice 28
So the next number must be twice 56:

Each vertex of a quadrilateral is dilated by a factor of 1/2 about the point P (-3,7). What will be the effect on the perimeter of the resulting figure.
Answers
Note that the perimeter of any quadrilateral is the sum of its sides.
[tex]P=\sum ^n_{i\mathop=1}a_i[/tex]So it is always proportional to the length of any side,
[tex]P\propto a_i[/tex]Note that the dilation either stretches of compresses the sides.
For the factor 1/2, each side of the quadrilateral will get multiplied by 1/2, which simply means that the sides will get halved.
So the new perimeter is given by,
[tex]P^{\prime}=\sum ^n_{i=1}(\frac{1}{2}a_i)=\frac{1}{2}\sum ^n_{i=1}(a_i)=\frac{1}{2}P[/tex]Thus, the perimeter will also get halved due to the dilation.
Therefore, option A is the correct choice.

The range of a data set is said to be the difference between the highest value and the lowest value in the given set of data.
To find the difference in the ranges of the 2 sets of data, find the range of data set A, find the range of data set B, then subtract the range of A from B.
Thus, we have:
For data A:
Minimun data value = 08
Maximum data value = 35
Range of data set A = 35 - 08 = 27
For data set B:
Minimum data value = 01
Maximum data value = 30
Range of data set B = 30 - 01 = 29
Difference in the ranges = Range of set B - Range of set A = 29 - 27 = 2
Therefore, the difference in the ranges of the sets of data is 2

The response variable is the dependent variable that determines the outcome of the experiment.
The treatment of an experiment is the independent variable, and it determines the outcome of the experiment.
From the illustration given in this exercise, the control variable, the response variable, and the treatments are identified below with reasons.
1) The control variable = The mathematical abilities of the students
Reason: The students chosen for the experiment must have the same mathematical abilities to prevent bias in the results of the experiment.
