Using translation concepts, the graph of g(x) is given at the end of the answer.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
Function f(x) is a concave up parabola with vertex at (1, -5). For the translation g(x) = f(x + 2), we have that the function is shifted two units left, as:
g(x) = f(x + 2) = (x + 2 - 1)² - 5 = (x + 1)² - 5.
Which is a concave up parabola with vertex at (-1, -5), and the graph is given at the end of the question.

Gary's is a small publishing company that publishes math books.
the production costs include a one time cost for editing which is $1050 for the book the company is currently working on. once the book is in production, the only cost will be the variable cost, of printing which is $15 per book. the company will market the book at a price of $35.
if you were to plot a graph of the profit generated by the book, what would the slope and y intercept represent?
Answers
The slope of the graph is 20 and the y-intercept is -1050.
The slope of a linear graph is defined as the gradient of the graph .It is also defined by trigonometric properties as the tangent of the angle formed by the line with the positive y-axis.
The y-intercept is the point of intersection of the graph and the y-axis.
The general equation of a straight line in the cartesian plane is given by
y = m x + c where 'm' represents the slope and 'c' represents the y-intercept.
It is given that the one time editing cost is 1050 dollars.
Variable cost of printing each book = 15 dollars
Each book is sold at = 35 dollars
∴profit per book sold = 35 - 15 = 20 dollars
Let Gary sells x number of books . Profit from selling x books = 20 x
Let us consider the net profit of Gary after selling x books be represented by y.
∴ y = profit from x books - establishment cost
or, y = 20 x -1050
Now comparing the above equation with the general equation of a straight line( y = mx + c ) we can infer that:
slope(m) = 20
y-intercept (c) = -1050
Therefore the slope of the graph is 20 and the y-intercept is -1050.

Using integrals, we have that:
a) The mean is of 1205 and the standard deviation is of 2.87.
b) P(1200 < X < 1202) = 0.2.
What is the probability distribution?The distribution is given by:
f(x) = 0.1, 1200 < x < 1210.
The integral of this function will be used to find the probabilities.
The mean of the distribution is given by:
[tex]\mu = \int_{1200}^{1210} xf(x) dx[/tex]
Hence:
[tex]\mu = \int_{1200}^{1210} 0.1x dx [/tex]
[tex]\mu = 0.05x^2|_{x = 1200}^{x = 1210}[/tex]
Hence the mean is:
0.05(1210² - 1200²) = 1205.
The variance of the distribution is given by:
[tex]\sigma^2 = \int_{1200}^{1210} (x - \mu)^2 f(x) dx[/tex]
Hence:
[tex]\sigma^2 = \int_{1200}^{1210} 0.1(x - 1205)^2 dx[/tex]
[tex]\sigma^2 = 0.033(x - 1205)^3|_{x = 1200}^{x = 1210}[/tex]
[tex]\sigma^2 = 0.033(1210 - 1205)^3 - 0.033(1200 - 1205)^3[/tex]
[tex]\sigma^2 = 8.25[/tex]
The standard deviation is the square root of the variance, hence:
[tex]\sigma = \sqrt{8.25} = 2.87[/tex]
For item b, the probability is given by:
[tex]P(1196 < X < 1202) = \int_{1200}^{1202} 0.1 dx[/tex]
P(1196 < X < 1202) = 0.1x, from x = 1200 to x = 1202.
Applying the Fundamental Theorem of Calculus:
0.1(1202) - 0.1(1200) = 0.2.
The lower bound is of 1200 because the distribution is not defined for values less than 1200.
Hence:
P(1200 < X < 1202) = 0.2.

A. -8.264264264...
B. -5/9
C. 17.47
D. 4.28192489...
*
Answers
Answer:
D
Step-by-step explanation:
Irrational numbers are those which cannot be expressed by the ratio of two integers.
A is rational because it is a recurring decimal. Recurring decimals can be represented by the ratio of two integers (this one can be represented by the fraction -2752/333, which is a ratio of two integers).
B is a fraction with two integers, therefore it is rational. -5/9 is a ratio of two integers.
C can be represented by 1747/100.
D is an infinite decimal but isn't recurring like A, meaning it cannot be represented by the ratio of two integers, and is therefore it is irrational, unless you are shown further digits of the decimal which prove it to be recurring, which is not the case here.
You consider buying a phone from one of two cell phone carriers. The table shows the total costs (in dollars) of the phone and service for different numbers of months at Carrier A . The total cost y (in dollars) of the phone and x months of service at Carrier B is represented by the equation y=55x+300 . Which carrier has the lower initial fee? After how many months of service are the total costs the same?
Answers
Using linear functions, we have that:
Carrier B has the lower initial fee.They will have the same amount after 10 months.What is the missing information?The table for Carrier A is missing and has two points (3,500) and (6,650).
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For Carrier B, the function is:
yB(x) = 55x + 300.
For Carrier A, when in 3 months, the price increases by $150, hence the slope is:
m = 150/3 = 50.
Hence:
yA = 50x + b.
When x = 3, y = 500, hence we use it to find b as follows.
500 = 50(3) + b
b = 350.
Then:
yA = 50x + 350.
Due to the lower intercept, we have that:
Carrier B has the lower initial fee.
They will have the same amount when:
yA = yB.
Hence:
50x + 350 = 55x + 300
5x = 50
x = 10 months.

what is the values of a and b
Answers
After evaluation we get the values as a = 8 + -0.4285714286b
Given, the expression is (7a ₊ 10)/(3b ₊ 6) = 72
Simplifying
(7a ₊ 10) ₊ (3b ₊ 6) = 72
Reorder the terms:
(10 ₊ 7a) ₊ (3b ₊ 6) = 72
Remove parenthesis around (10 ₊ 7a)
10 ₊ 7a ₊ (3b ₊ 6) = 72
Reorder the terms:
10 + 7a + (6 + 3b) = 72
Remove parenthesis around (6 + 3b)
10 + 7a + 6 + 3b = 72
Reorder the terms:
10 + 6 + 7a + 3b = 72
Combine like terms: 10 + 6 = 16
16 + 7a + 3b = 72
Solving
16 + 7a + 3b = 72
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + 7a + -16 + 3b = 72 + -16
Reorder the terms:
16 + -16 + 7a + 3b = 72 + -16
Combine like terms: 16 + -16 = 0
0 + 7a + 3b = 72 + -16
7a + 3b = 72 + -16
Combine like terms: 72 + -16 = 56
7a + 3b = 56
Add '-3b' to each side of the equation.
7a + 3b + -3b = 56 + -3b
Combine like terms: 3b + -3b = 0
7a + 0 = 56 + -3b
7a = 56 + -3b
Divide each side by '7'.
a = 8 + -0.4285714286b
Simplifying
a = 8 + -0.4285714286b
hence we get the solution of the equation.

He wouldn’t be able to meet the specifications as the heigh is greater than the maximum height.
In mathematics, the greater than sign is a basic mathematical notation used to represent an inequality between two values. The symbol used to denote greater inequality is “>”. It is the commonly accepted mathematical notation of two strokes of equal length that meet at an acute right angle. A typical use of the greater than sign is to compare two values, where the first is greater than the second, or one is greater than the other. The greater than sign is an approximation of a closing square bracket.Maximum width of the wall hanging can be 3.75 feet and maximum height can be 6.5 feet.
After completing the work it was found that the width measures 3 3/5 feet and height was 3 3/4 tall.

Answers
Larry Mitchell invested $7600 at 3% rate of interest and $11400 at 2% rate of interest.
In the field of finance, interest is the payment of a sum over and above the principal amount owed by a lender or depositor to a borrower or deposit-taking financial institution at a set rate.
Rate of an interest in defined as the amount that a lender charges a borrower in interest as a percentage of the principal.
Larry invested part of his $19000 at 3% and the rest at 2%
Let he invested $'x' at 3% interest .
Therefore amount invested at 2%=$(19000-x)
Interest earned annually at 3% on $x = [tex]\frac{3}{100} \times x =0.03x[/tex] .
Interest earned annually at 2% on $(19000-x)=[tex]\frac{2}{100} \times(19000-x)[/tex]
=[tex]380-0.02x[/tex]
Now the combined interest for both the investment is $560 .
Therefore we can form a linear equation to solve for x:
0.03x+380-0.02x=560
or, 0.01x=180
or, x=18000
Therefore Larry invested $18000 at 3% interest.
Money invested at 2%=$(19000-18000)=$1000
Hence Larry invested $18000 at 3% rate of interest and $1000 at 2% rate of interest.
