Choose the function that represents the graph of the transformation of f(x) = |x| that opens down and has a vertex of (3,2)
f(x) = |x - 3| - 2
f(x) = -|x - 3| + 2
f(x) = |x + 3| + 2
f(x) = -|x + 3| + 2
Answer:
f(x) = -|x - 3| + 2.
Step-by-step explanation:
f(x) = |x| is shaped like a V and the vertex is at (0, 0). f(x) = -|x| is a reflection in the x-axis so will be an inverted V , opening down. f(x) = - |x - 3| will be the -|x| moved 3 units to the right with the vertex at (3, 0). To bring the vertex to (3, 2) it will move upwards 2 units.
So it is f(x) = -|x - 3| + 2.
f(x)=-|x-3|+2
Negative before the abs value inverts the graph and it moves right 3 and up 2

The SSS proof used the rigid transformations illustrated here. Which transformations are used?
Answer:A translation then rotation then reflection
Step-by-step explanation:
In the context of the Side-Side-Side (SSS) theorem in geometry, the rigid transformations referred to are typically translation, rotation, and reflection. By strategically applying these transformations, one can map one triangle onto another, thereby demonstrating their congruence according to the SSS theorem.
Explanation:Rigid transformations in the context of geometry often refer to transformations that preserve the shape and size of geometric figures. The characterization quoted as 'SSS proof' likely refers to the Side-Side-Side congruence theorem in geometry, which states that if the three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. This congruence can be proven through certain rigid transformations, most commonly, translation, rotation and reflection.
In the case of the SSS proof, one or a combination of these three transformations can be used to map one triangle onto another. For example, you can translate one triangle so that a vertex matches a corresponding vertex on the other triangle. Then rotate the translated triangle if necessary so that one side matches the direction of the corresponding side on another triangle, this is rotation. Finally, if the triangle is flipped relative to the other one, reflect along the appropriate axis to match the final side. Again, this is the most common example and sometimes you may need to combine the transformations.
The inquiry about Einstein's postulate and other references seems unrelated to rigid transformations in Geometry and the SSS proof specifically.

What is the value of x in this triangle? Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth. X = ° A right triangle. The perpendicular is labeled as 5. The base is labeled as 20. The alternate base angles are labeled as right angle and x degrees
Answer:
14.04°
Step-by-step explanation:
In this right triangle, we're seeking the measurement of an angle at the base of the triangle and we have the measurements of two of the sides (none are the hypotenuse) : the opposite one of the angle and the adjacent side.
The relationship between the two sides we have the measurement and the angle we are looking for is the tangent:
[tex]tan(\alpha) = \frac{a}{b} = \frac{5}{20} = 0.25[/tex]
To find the angle we do an arctan on 0.25 and we get an angle of 14.04 degrees.

D. Asking students to call a phone number to answer survey questions
Step-by-step explanation:
A random sample is choosing the first 100 students who arrive at school.
What are the different types of sampling techniques ?There are five types of Sampling Techniques
Random sampling is similar to putting everyone's name into a bowl and drawing out random names. Each element has a chance of being called.
Systematic sampling is easier to do than random sampling. In systematic sampling, the list of elements is "counted off". That is, every kth element is taken.
Convenience sampling is very easy to do, but it is the least effective technique to use. In convenience sampling, data that is easily available is used.
Cluster sampling is accomplished by dividing the population into groups usually geographically. These groups are called clusters or blocks. The clusters are randomly selected, and each element in the selected clusters are used.
Stratified sampling also divides the population into groups called strata. However, this time it is by some characteristic, not geographically.
Option C , i.e. Choosing the first 100 students who arrive at school is an example of Random Sampling.

Best regards
Final answer:
Venture capital is money loaned for the purpose of earning a share of the profits in startups or small businesses. Venture capitalists provide funds in exchange for equity in the company.
Explanation:
Venture capital is money loaned for the purpose of earning a share of the profits. It is a form of financing for startups or small businesses that have potential for high growth. Venture capitalists provide funds to these companies in exchange for equity, or ownership stake, in the company.
For example, let's say a student wants to start a tech company but doesn't have the funds to do so. They approach a venture capitalist who believes in their idea and is willing to invest money in their company. In return, the venture capitalist will receive a portion of the company's profits.
So, the correct answer is D. Venture capital.
What is the solution to the following system of equations? 2x+3y=4 x+y=3
Answer:
(5, -2)
Step-by-step explanation:
x + y = 3 can become x = 3-y
we are going to use substitution
now plug x = 3-y into the other equation
2(3-y) + 3y = 4
6-2y+3y = 4
6 + y = 4
subtract 6 from both sides
y = -2
now plug in y back into one of the equations, it doesn't matter which one. I am going to use the x + y = 3 equation
x -2 = 3
x = 5

Round to three decimal places as needed.)A. P(F or G)=_______+_______−________=_______B. P(F or G)=_______+_______=________
Answer:
A) F or G = {5, 6, 7, 8, 9, 10, 11, 12}; B) P(F or G) = 8/12 = 0.667
Step-by-step explanation:
The outcomes in event F are 5, 6, 7, 8 and 9. The outcomes in event G are 9, 10, 11 and 12. This means that the event F or G, containing all elements of both events, will be
{5, 6, 7, 8, 9, 10, 11, 12}. Note that we do not count 9 twice; it only appears in the sample space once. There are 8 elements out of 12 total in the sample space; this means the probability is 8/12 = 0.667.
Using the addition rule, we begin with P(F). There are 5 elements in this event; this makes P(F) = 5/12.
For P(G), there are 4 elements in G; this makes P(G) = 4/12.
To add them, we add P(F) and P(G) but then must take out the element counted twice; this gives us
5/12+4/12-1/12 = 9/12-1/12 = 8/12 = 0.667.
We have that
F&G={5, 6, 7, 8, 9, 10, 11, 12}[tex]P(FG)=0.667[/tex][tex]P(F or G)=5/12+4/12-(1/12)\\\\ P(F or G)=5/12+1/4[/tex]From the question we are told
S={ 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}, F={5, 6, 7, 8, 9}G={9, 10, 11, 12}
a)
Generally
The P(F or G) by counting the number of outcomes in F or G is
F&G={5, 6, 7, 8, 9, 10, 11, 12}
b)
P(F or G) using the general addition rule
[tex]P(FG)=\frac{N_f}{N_g}\\\\P(FG)=\frac{8}{12}[/tex]
[tex]P(FG)=0.667[/tex]
c)
Generally Using addition Rue to attain P(F or G) we have
For P(F or G)
[tex]P(F or G)=PF+PG-P(F+G)[/tex]
[tex]P(F or G)=5/12+4/12-(1/12)\\\\ P(F or G)=5/12+1/4\\\\ P(F or G)=\frac{8}{12}[/tex]

Express cos 7pi/3 as a trigonometric functions of an angle in quadrant 1 (picture provided)
Answer:
[tex]Cos (\frac{\pi}{3})[/tex]
Step-by-step explanation:
To get the angle in the first quadrant, we need to subtract 2π from the angle given as many times we need UNTIL we get an angle that is between 0 degree and 90 degree (1st quadrant).
Let's start by subtracting 2π from the angle given:
[tex]\frac{7\pi}{3}-2\pi\\=\frac{7\pi -2\pi(3)}{3}\\=\frac{7\pi - 6\pi}{3}\\=\frac{\pi}{3}[/tex]
This angle is in the 1st quadrant, so we don't need to subtract 2π anymore. Thus we can write:

My niece wanted to create a coverup she saw on Pinterest. It required a square piece of patterned fabric. We found an online store with some bright and fun samples of fabric at a reasonable price. They charge a flat shipping fee of $10 and then $3 per yard.
The formula 3n + 10 = t can be used to determine the total cost of the fabric, where n is the number of yards purchased, and t is the total cost of the fabric
1.1. What is the dependent variable (or write “neither” if there is not one)? _______________
Explain why or why not:
Answer:
The dependent variable is the total cost "t"
Explanation:
The given equation is:
3n + 10 = t
where n is the number of yards and t is the total cost
We have two variables in this equation, n and t
We know that the total cost "t" will depend on the number of yards of fabric she buys
This means that the total cost will change by changing the number of yards bought
For example:
If she bought 1 yard: t = 10 + 3(1) = $13
If she bought 3 yards: t = 10 + 3(3) = $19
Therefore, the total cost "t" depends on the number of yards which means that "t" is the dependent variable in the equation

The tuition at a college increased from 50,000 in 2006 to to 59,000 in 2007. What is the percent increase in tuition
Answer:
18%
Step-by-step explanation:
18% is the percent increase in tuition fees.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, The tuition at a college increased from 50,000 in 2006 to 59,000 in 2007.
From the general formula of percentage change,
percentage change = change in value/original value * 100
In our case,
original value = 50,000
change in value = 59,000 - 50,000
change in value = 9,000
thus,
Percentage change = 9,000/50,000 *100
Percentage change = 18%
Therefore, the percent increase in tuition fees is 18%.

b.find a parametrization of the curve x2/3+y2/3=42/3 and use it to compute the area of the interior. hint: x(t)=4cos3(t).
The area of the ellipse [tex]E[/tex] is given by
[tex]\displaystyle\iint_E\mathrm dA=\iint_E\mathrm dx\,\mathrm dy[/tex]
To use Green's theorem, which says
[tex]\displaystyle\int_{\partial E}L\,\mathrm dx+M\,\mathrm dy=\iint_E\left(\frac{\partial M}{\partial x}-\frac{\partial L}{\partial y}\right)\,\mathrm dx\,\mathrm dy[/tex]
([tex]\partial E[/tex] denotes the boundary of [tex]E[/tex]), we want to find [tex]M(x,y)[/tex] and [tex]L(x,y)[/tex] such that
[tex]\dfrac{\partial M}{\partial x}-\dfrac{\partial L}{\partial y}=1[/tex]
and then we would simply compute the line integral. As the hint suggests, we can pick
[tex]\begin{cases}M(x,y)=\dfrac x2\\\\L(x,y)=-\dfrac y2\end{cases}\implies\begin{cases}\dfrac{\partial M}{\partial x}=\dfrac12\\\\\dfrac{\partial L}{\partial y}=-\dfrac12\end{cases}\implies\dfrac{\partial M}{\partial x}-\dfrac{\partial L}{\partial y}=1[/tex]
The line integral is then
[tex]\displaystyle\frac12\int_{\partial E}-y\,\mathrm dx+x\,\mathrm dy[/tex]
We parameterize the boundary by
[tex]\begin{cases}x(t)=5\cos t\\y(t)=17\sin t\end{cases}[/tex]
with [tex]0\le t\le2\pi[/tex]. Then the integral is
[tex]\displaystyle\frac12\int_0^{2\pi}(-17\sin t(-5\sin t)+5\cos t(17\cos t))\,\mathrm dt[/tex]
[tex]=\displaystyle\frac{85}2\int_0^{2\pi}\sin^2t+\cos^2t\,\mathrm dt=\frac{85}2\int_0^{2\pi}\mathrm dt=85\pi[/tex]

Notice that [tex]x^{2/3}+y^{2/3}=4^{2/3}[/tex] kind of resembles the equation for a circle with radius 4, [tex]x^2+y^2=4^2[/tex]. We can change coordinates to what you might call "pseudo-polar":
[tex]\begin{cases}x(t)=4\cos^3t\\y(t)=4\sin^3t\end{cases}[/tex]

[tex]x(t)^{2/3}+y(t)^{2/3}=(4\cos^3t)^{2/3}+(4\sin^3t)^{2/3}=4^{2/3}(\cos^2t+\sin^2t)=4^{2/3}[/tex]
as needed. Then with [tex]0\le t\le2\pi[/tex], we compute the area via Green's theorem using the same setup as before:
[tex]\displaystyle\iint_E\mathrm dx\,\mathrm dy=\frac12\int_0^{2\pi}(-4\sin^3t(12\cos^2t(-\sin t))+4\cos^3t(12\sin^2t\cos t))\,\mathrm dt[/tex]
[tex]=\displaystyle24\int_0^{2\pi}(\sin^4t\cos^2t+\cos^4t\sin^2t)\,\mathrm dt[/tex]

The areas of the ellipse and curve interior can be calculated using Green's Theorem and the respective parametrizations, x(t) = 5cos(t) and x(t) = 4cos3(t), followed by integrating.
Explanation:To compute the area inside the ellipse using Green's Theorem, we use the fact that the area can be written as ∬ dxdy = 1/2 ∫ d(−y dx+x dy). Using the hint, x(t) = 5cos(t), we parametrize the ellipse and integrate over the boundary to compute the area.
Similarly, for the parametrization of the curve x2/3 + y2/3 = 42/3, we could use the hint x(t) = 4cos3(t), which is a cube root form representation. After this, compute the area of the interior using the proper integration methods.
