Eric and Nancy both had a successful year selling fish tanks for theirrespective employers, and so they were both given raises.Eric: Eric's base salary is still $1400, but now he makes a commission of$100 for each fish tank that he sells.Nancy: Nancy now gets a base salary of $500 per month, but her commissionhas stayed the same at $250 per fish tank.Eric and Nancy still want to make sure that they contribute the same amountto their total monthly income, and Nancy proposes using algebra to figureout how many fish tanks that they would each need to sell. She tells Ericthat he can calculate his monthly income by using the formula f(x) = 100x +1400. She says that she can calculate her own salary by using the functiong(x)=250x + 500.1 What does the variable x represent in Nancy's formulas?How do you know?
Answers
Answer:
The variable x represents the number of fish tanks he/she sells.
Explanation:
Given that Eric's base salary is still $1400, but now he makes a commission of
$100 for each fish tank that he sells and Nancy now gets a base salary of $500 per month, but her commission has stayed the same at $250 per fish tank.
Eric's total income would be;
$1400 plus $100 times the number of fish tanks he sells.
[tex]f(x)=1400+100x[/tex]and Nancy's total income would be;
$500 plus $250 times the number of fish tanks she sells.
[tex]f(x)=500+250x[/tex]Therefore, the variable x represents the number of fish tanks he/she sells.
The number of fish tanks each of them sells will determine the total commission and also determines their total income.

The value of the set (A∪C)'∩B is {9 , 12} .
A subfield of mathematical logic called set theory examines sets, which are essentially collections of objects.
Set theory is a discipline of mathematics that largely addresses problems that are pertinent to mathematics as a whole, despite the fact that any kind of object can be constructed into a set.Set theory is founded on a simple binary relationship between an object o and a set A.It is written as o A if o is a part (or member) of A. Members of a set are enumerated with commas to denote separation when describing them, or a property of those parts is enclosed in braces.Sets can be associated by the membership relation since they are objects.The given sets are:
U ={1,2,3,4,5,6,7,8,9,10,11,12,13}
A = {3,7,11,13}
B = {3,6,9,12,13}
C = {2,3,5,6,7,8}
Now B' = {1,2,4,5,7,8,10,11}
b) B'∩C = {2,5,7,8,}
c) A∪C = {2,3,5,6,7,8,11,13}
(A∪C)' = {1,4,9,10,12}
(A∪C)'∩B = {9 , 12}
Hence the value of the set (A∪C)'∩B is {9 , 12} .

The number written in scientific notation is 1.12 × 10⁻² .
Scientific notation can be used to describe values that are either too large or too little to be conveniently presented in decimal form (typically would result in a long string of digits).
In the UK, it is also known as standard form, scientific form, and standard index form.Since it may make a number of mathematical operations simpler, this base ten notation is frequently employed by scientists, mathematicians, and engineers.Scientific notation for non-zero integers is written as m × 10ⁿ, or m times ten and raised to the power of n, where n is an integer and m is a non-zero real number.The given number is 4.501795324E⁻⁶
So simplifying we get :
4.501795324E⁻⁶ = 1.11588350 × 10⁻²
Therefore the number written in scientific notation is 1.12 × 10⁻² .

A side mirror of a small pick up truck is similar to that of a larger full size pickup truck. If the smaller truck has a rectangular side mirror of width 5.0 in. and height 6.0 in., what is the height in inches of the larger mirror if the width is 10.0 in.?
Answers
If the width of larger full size pickup truck is 10.0 in. then its height is equal to 12inches.
As given in the question,
Side mirror of a small pick up truck is similar to larger full size pick up truck.
Smaller truck has rectangular side mirror
Width = 5.0 in.
Height = 6.0 in.
Larger mirror
Width = 10.0 in.
Let h be the height of the larger mirror
Both the mirrors are similar and rectangular in shape.
Hence, sides are in proportion
5 /6 = 10 /h
⇒h = (6 ×10) / 5
⇒ h = 12 in.
Therefore, if the width of larger full size pickup truck is 10.0 in. then its height is equal to 12inches.

Lets assume that the input values are x values and the output values are y values.
Then you will have pairs of coordinate values as shown;
(-1,7) , (0,2) , (1,-3) , (2,-8), (3,-13), (4,-18)
Using the coordinates find the slope a;
(-1,7) and (0,2) ---------slope is change in y-values/ change in x-values , (2-7) /(0--1)
= -5/ 1 = -5
Do the same for the next pair of coordinates ,(0,2) and (1,-3) , (-3-2) / (1-0) = -5/1 = -5
If you continue the procedure to the next pair which is (1,-3) and (2,-8) to get the slope as : (-8- -3) / (2-1) = -5/1 = -5
This means that the slope is -5
The relation will be represented by the equation y= mx + c where m is the slope and c is the y-intercept
First plot the points to visualize the graph
From the plot, you notice that when the points are joined, a straight graph is formed sloping to the negative side and intersecting the y-axis at point (0,2).
So to determine the rule, we apply the equation y= mx + c with m= -5 and c =2
This gives y= -5 x + 2

Answers
a) The required down payment is $47,800.
b) The mortgage loan is $191,200.
c) The amount for the three points at closing is $5,736, which is 3% of the mortgage.
d) The monthly payment (excluding escrowed taxes and insurance) is $-1,677.92.
e) The total interest cost for the mortgage over its 30-year period is $412,850.06.
What is the down payment?The down payment is an upfront payment required to reduce the mortgage loan and assure the financier that the mortgagee is financially ready to engage in the mortgage transaction.
The price of a dream house = $239,000
Down payment = 20% = $47,800 ($239,000 x 20%)
Mortgage loan = $191,200 ($239,000 - $47,800)
Three points at closing = 3% of $191,200
= $5,736
Periodic Payment:N (# of periods) 360 months (30 years x 12)

-3 + (-2) = -5 (Sum)
The polynomial may be expressed as follows after dividing the middle term by the two components, -3 and -2:
x² - 3x - 2x + 6 = 0

The error interval for the combined mass (m) of the car and the person is 2047.7 ≤ m < 2049.7
What is an inequality?An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments (symbols):
Greater than (>).Less than (<).Greater than or equal to (≥).Less than or equal to (≤).The error interval for the mass of car is given by:
Mass of car = 1990 ± 0.5;
Mass of car = 1990 + 0.5 = 1990.5
Mass of car = 1990 - 0.5 = 1989.5
The error interval for the mass of a person is given by:
b = 1990 ± 0.5;
b = 58.7 + 0.5 = 59.2
b = 58.7 - 0.5 = 58.2
For the value of a and b, we have:
a = 1989.5 + 58.2 = 2047.7
b = 1990.5 + 59.2 = 2049.7
Next, we would calculate the combined mass (m):
m = 1990 + 58.7
m = 2048.7

The population of a small town in central Florida has shown a linear decline in the years 1995-2005. In 1995 the population was 24100 people. In 2005 it was 14800 people.

Part A:
Since the population is showing a linear decline, we can express the function P(t) as

We will use the point (2005,14800), but using (1995,24100) will work just as well.
[tex]\begin{gathered} \text{IF }m=-930,\text{ and }(x,y)=\mleft(2005,14800\mright),\text{ THEN} \\ \\ y=mx+b \\ 14800=(-930)(2005)+b \\ 14800=-1864650+b \\ 14800+1864650=+b \\ 1879450=b \\ b=1879450 \end{gathered}[/tex]Convert the function x into a function of time t, then the the function is
[tex]P(t)=-930t+1879450[/tex]Part 2:
What will be the population in 2007.
Substitute t = 2007.
[tex]\begin{gathered} P(t)=-930t+1879450 \\ P(2007)=-930(2007)+1879450 \\ P(2007)=-1866510+1879450 \\ P(2007)=12940 \end{gathered}[/tex]Therefore, in the year 2007, the population will be 12940.
