The graph of F(x), shown below, has the same shape as the graph ofG(x) = x - x? Which of the following is the equation of F(x)?F(x) = ?
The graph of G(x) is symmetric with respect to the y-axis. It also passes through the origin.
Since the graph of F(x) moved 4 units upward, we must add 4 to the right of the equation. Thus, the equation of F(x) is as follows.

Answer:
Area = 4πr²
Step-by-step explanation:
- We know that a moon revolves around its orbit as per Keplar. The moon is not a perfect sphere, so we shall take an assumption;
Assume the moon is a perfect and regular sphere
[tex]{ \tt{volume \: of \: moon = \frac{4}{3} \pi {r}^{3} }} \\ \\ { \boxed{ \tt{ \: v = \frac{4}{3} \pi {r}^{3} }}}[/tex]
- From engineering mathematics (rates of change), we know that volume is first order integral of area and area is the first order derivative of volume;
[tex]{ \tt{area = \frac{d(volume)}{dr} }} \\ \\ { \tt{volume = \int area \: dr}}[/tex]
- So, from our formular;
[tex]{ \tt{area = \frac{dv}{dr} = \frac{4}{3}\pi ( \frac{d ({r}^{3} )}{dr} ) }} \\ \\ { \tt{area = \frac{4}{3}\pi(3 {r}^{2}) }} \\ \\ { \boxed{ \rm{area = 4\pi {r}^{2} }}}[/tex]
r is radius of the moon[tex]{ \boxed{ \mathfrak{DC}}}{ \underline{ \mathfrak{ \: delta \: \delta \: creed}}} \\ [/tex]
C Dorothy drew a rectangle with length of 14.3 centimeters and width of 13.9 centimeters. Find its area (nearest tenth).

At a sale a sofa is being sold for 67% of the regular price. The sale price is $469. What is the regular price?
We have the following information:
• At a sale, a sofa is being sold for ,67% of the regular price
,• The sale price is $469
And we need to determine the regular price.
To find it, we can proceed as follows:
1. Let x be the regular price. Then we have:
[tex]\begin{gathered} 67\%=\frac{67}{100} \\ \\ 67\%(x)=\frac{67}{100}x \\ \\ \text{ Then we know:} \\ \\ \frac{67}{100}x=\$469 \end{gathered}[/tex]2. Now, we have to solve for x as follows:
[tex]\begin{gathered} \text{ Multiply both sides by }\frac{100}{67}: \\ \\ \frac{67}{100}*\frac{100}{67}x=\frac{100}{67}*\$469 \\ \\ x=\frac{100*\$469}{67}=\$700 \\ \\ x=\$700 \end{gathered}[/tex]Therefore, in summary, the regular price is $700.
Given the diagram, classify the bolded line as a perpendicular bisector, angle bisector, median or alritude. I chose angle bisector. Am I right?

Simplify the expression √112x10y13. Show your work. pls help
Answer: [tex]4x^{5} y^{6} \sqrt{7y}[/tex]
Step-by-step explanation:
1) Separate the radicals
sqrt(112x^10y^13) = sqrt(112)*sqrt(x^10)*sqrt(y^13)
2) For sqrt(112), rewrite it as the product of a perfect square and some other number.
sqrt(112) = sqrt(16) * sqrt(7)
= 4*sqrt(7)
3) For sqrt(x^10), rewrite it in terms of it being raised to a fraction
[tex]\sqrt[n]{x} = x^{\frac{1}{n} }[/tex]
n = 2, so x^(10/2), and when simplified you have x^5
4) For sqrt(y^13), do the same thing.
y^(13/2) = sqrt(y)*(y^6)
5)Combine everything
4x^5y^6sqrt(7y)

Suppose you have a monthly entertainment budget that you use to rent movies and purchase cds. You currently use your income to rent 5 movies per month at a cost of 5.00 per movie and to purchase 5 cds per month at a cost of 10 per cd. Your marginal utility from the fifth movie is 30 and your marginal utility from the fifth cd is 70
Total utility of movies and cds will be $160
What is Budget?
A spending plan based on income and costs is called a budget. In other words, it's a projection of your income and expenses for a specific time frame, like a month or a year. (Or, if you're keeping track of the money coming in and going out of your home as a whole, that's a family budget.)
The cost of 1 movie = $5
The cost of 1 CDS = $10
The marginal utility from fifth movie = 30
The marginal utility from fifth CDS = 70
Total cost spent in month for movies = 5+5+5+5+30
= $50
Total cost spent in month for CDS = 10+10+10+10+70
= $110
The total monthly entertainment budget will be
= 50 + 110
= $160
Hence, The total monthly entertainment budget is $160

3.50 : 1.50 ratio as a fraction
Answer:
7/3
Step-by-step explanation:
You want the ratio 3.50 : 1.50 written as a fraction.
RatioA ratio can be written 3 ways. Any of them can be reduced to a ratio of mutually prime integers:
3.50 : 1.50 = 3.50/1.50 = 3.50 to 1.50
Here, the fraction can be made to be a ratio of integers by multiplying both numerator and denominator by 2:
3.50/1.50 = (2·3.50)/(2·1.50) = 7/3
The ratio 3.50:1.50 is equivalent to the fraction 7/3.

NO LINKS!! Describe the domain and range (in BOTH interval and inequality notation) for each function shown.
Answers:
Domain as an inequality: [tex]\boldsymbol{-\infty < \text{x} < \infty}[/tex]
Domain in interval notation: [tex]\boldsymbol{(-\infty , \infty)}[/tex]
Range as an inequality: [tex]\boldsymbol{-3 \le \text{y} \le 3}[/tex]
Range in interval notation: [-3, 3]
=================================================
Explanation:
The domain is the set of allowed x inputs. This graph goes on forever in both directions, so we can plug in any real number for x. There are no restrictions to worry about.
As an inequality, we write [tex]-\infty < \text{x} < \infty[/tex] to basically say "x is between negative infinity and infinity". In other words, x is anything on the real number line.
That inequality condenses into the interval notation of [tex](-\infty , \infty)[/tex]
Always use curved parenthesis for either infinity, because we can't ever reach infinity. It's not a number on the number line but rather a concept.
----------------------
Now onto the range.
Recall the range is the set of possible y outputs. We look at the lowest and highest points (aka min and max) to determine the boundaries for the range.
In this case, the smallest y can get is y = -3
The largest it can get is y = 3
The range is any value of y such that [tex]-3 \le \text{y} \le 3[/tex] which in word form is "any value between -3 and 3, inclusive of both endpoints".
That inequality condenses to the interval notation [-3, 3]
We use square brackets to include the endpoints as part of the range.
Answer:
[tex]\textsf{Domain}: \quad (-\infty, \infty) \quad -\infty < x < \infty[/tex]
[tex]\textsf{Range}: \quad [-3,3] \quad -3\leq y\leq 3[/tex]
Step-by-step explanation:
The domain of a function is the set of all possible input values (x-values).
The range of a function is the set of all possible output values (y-values).
Interval notation
( or ) : Use parentheses to indicate that the endpoint is excluded.[ or ] : Use square brackets to indicate that the endpoint is included.Inequality notation
< means "less than".> means "more than".≤ means "less than or equal to".≥ means "more than or equal to".From inspection of the given graph, the function is continuous and so the domain is not restricted.
Therefore, the domain of the function is:
Interval notation: (-∞, ∞)Inequality notation: -∞ < x < ∞From inspection of the given graph, the minimum value of y is -3 and the maximum value of y is 3. Both values are included in the range.
Therefore, the range of the function is:
Interval notation: [-3, 3]Inequality notation: -3 ≤ y ≤ 3i want to ask a question

Overnight the price of gasoline increased by 15% to settle at a price of $4.90 per gallon. What was the price before the 15% increase?
The price of gasoline before the 15% increase is $4.75/gallon.
What is gasoline?
Petroleum-derived clear flammable liquid known as gasoline or petrol is the primary fuel for the majority of spark-ignited internal combustion engines (also known as petrol engines). It mostly comprises of organic compounds made from petroleum fractional distillation that have been improved with various additions. In the United States, refineries typically create 19 to 20 gallons of gasoline, 11 to 13 gallons of distillate fuel, the majority of which is sold as diesel fuel, and 3 to 4 gallons of jet fuel from a barrel of crude oil. The crude oil test and oil refinery processing determine the product ratio. 42 US gallons, or around 159 litres or 35 imperial gallons, is the standard measurement for the volume of an oil barrel.
How can we calculate the price before the 15% increase?
Overnight the price of gasoline increased by 15% to settle at a price of $4.90 per gallon.
15÷100+x = $4.90/gallon
0.15+x = $4.90/gallon
Therefore, x = $4.90/ gallon - 15÷100
x = $4.90/gallon - 0.15
x = $4.75/gallon.
Hence , the price of gasoline before the 15% increase is $4.75/gallon.
