Describe the composition of translations.
translation: (x, y)__
translation: {x, y)__
Answers
The composition of translations for the first image is (x+1, y+5) and for the second image is (x-4, y).
What is a translation?
A transformation that moves a figure through its points using a given ruler—a translation vector—is referred to as a translation. Without altering the original geometry, this process moves each point in a picture both horizontally and vertically.
Given a graph of translation
The first image is translated as 1 unit upward and 5 units right side.
Then, translation (x,y) → (x+1, y+5)
And,
The second image is translated as 4 units downward only.
Then, translation (x,y) → (x-4, y)
Hence, the above is the required composition of translations.

A store owner decides to mark up all items by 30%. What is the selling price of an item that originally cost $30?
Answers
After the markup, the selling price of the item will be $39.
What is the selling price of an item that originally cost $30?
We know that a store owner decides to mark up all items by 30%, so basically we need to increase all the costs by 30%.
If the original cost is C, then the cost after the mark up will be:
P = C*(1 + 30%/100%)
P = C*(1 + 0.3)
P = C*(1.3)
In this case, we want to find the selling price P for an object whose original cost C is $30, then we can replace C in the equation above so we get:
P = $30*1.3 = $39
The selling price P is $39.

The ratio of Pablo's age to Richard's age is 6 : 7. The ratio of Pablo's age to Tristan's age is 5 : 4. Find the ratio of Pablo's age to Richard's age to Tristan's age.
Answers
Ages of Tristan, Richard, and Pablo are in the order 6:7:4.
Detailed explanation:
Pablo is six years younger than Richard, seven years older than Tristan, and five years younger than Richard.
We can multiply the ratios of Pablo's age to Richard's age and Pablo's age to Tristan's age to determine the ratio of Tristan's age to Richard's age before determining the ratio of Tristan's age to Pablo's age.
These ratios add up to 6/7 * 5/4 = 30/28.
Pablo's age to Richard's age is 6:7, thus we may multiply this ratio by the age of Richard by Tristan's age to determine the age of Pablo, Richard, and Tristan.
Thus, the ratio of Pablo's age to Richard's age to Tristan's age is 6:7:4.

Determine the equation for the line. Write the equation in standard form through
the points
(3,-4) and (6,-2)
Answers
The standard form equation for the line through the points (3,-4) and (6,-2) is -2/3 x + y = 4.
What is the equation of the line passing through the two-point?
To find the equation for the line through two points we can use the formula:
y - y1 = m(x - x1)
where (x1, y1) is one of the points, and m is the slope of the line. The slope of the line is equal to the change in y over the change in x, which can be calculated as:
m = (y2 - y1) / (x2 - x1)
where (x2, y2) is the other point.
Substituting the given points and the formula for the slope into the formula for the equation of the line, we get:
y - (-4) = ((-2) - (-4)) / (6 - 3) (x - 3)
This simplifies to:
y + 4 = -2/3 (x - 3)
To write the equation in standard form, we can distribute the -2/3 and then rearrange the terms:
-2/3 x + y = 4
Hence, the standard form equation for the line through the points (3,-4) and (6,-2) is -2/3 x + y = 4

Give your answer in whole people.
Answers
The incumbent is the current holder of an office or position, usually in relation to an election.
Who is a political candidate?In the context of elections for public office in a representational partisan democracy, a candidate who has been selected by a political party is normally said to be the nominee of that party.Today, in 48 states, individuals participate in primaries or caucuses to elect delegates who support their presidential candidate of choice. At national party conventions, the presidential contender with the most state delegate votes wins the party nomination.This usually happens through the party's state primaries and caucuses. State delegates go to the national convention to vote to confirm their choice of candidates. But if no candidate gets the majority of a party's delegates during the primaries and caucuses, convention delegates choose the nominee.In most states, state offices include: Governor, Lieutenant Governor, Secretary of State, and Attorney General, State Supreme Court Justices, Comptroller, Treasurer, State Senators, and State Legislators.
The variable of interest is:
X: Number of people that support the candidate.
You need to calculate the sample size to estimate the population proportion of supporters given a confidence level of 99% and a margin of error of 4%
The margin of error of the confidence level for the population proportion is
d = [tex]Z_{1} - \frac{\alpha }{2} * \sqrt{\frac{p^{|}(1 - p^{|} ) }{n} }[/tex]
=[tex]\frac{d}{Z_{1}-\alpha /2 } =\sqrt{\frac{p^{2}(1-p^{2} ) }{n} }[/tex]
sample proportion "p'" since there is no sample information, nor any previous information is known, you have to consider it as the "worse case scenario" and use the value of p'= 0.50
d= 0.04
She has to take a sample of 1045 people to estimate the population proportion of her supporters with a confidence level of 99% and a margin of error of 4%

b. To find the value of S(7), we substitute t = 7 into the function: S(7) = 1.084(7) + 17.392 = 22.688.
c. In context, the value of S(7) represents the amount of money, in billions of dollars, that the US government spent on science, space, and technology 7 years after 1999.
d. The key feature that is found when solving S(t) = 0 is the y-intercept of the graph of S(t). The y-intercept is the point where the graph crosses the y-axis.
e. The value for S(t) = 0 is not reasonable for the context because it represents the amount of money spent on science, space, and technology in 1999, which would be a negative number of years after 1999.

One number is less than another number if their difference is less than zero.
Since x=2y-4 - 0.75 = -0.75 which is less than zero, x=2y-4 is less than 0.75
Therefore, x=2y-4 is 0.75 less/lower than 0.75
Find the slope of the line
Answers
Answer:
1/4 and -20
Step-by-step explanation:
"Slope" just means the change in y divided by the change in x. In the first graph, the slope is the change in depth divided by the change in hours.
Using the equation, slope = (y - y1)/(x - x1), you can plug in 2 points and solve. I see that the line goes through the points (4,1) and (8,2), so I'll use these. Make sure that (x,y) are from the same point and (x1,y1) are from the same point.
slope = (2 - 1)/(8 - 4)
slope = 1/4
You can do the same process for the second graph but you'll use different points. I see the points (2,80) and (4,40), so I'll use those.
slope = (40 - 80)/(4 - 2)
slope = -40/2
slope = -20

The correct option B. double; angle used to rotate the xy-coordinate plane to a new x'y'-plane for graphing a rotated conic section.
Explain the term rotated conic section?Any curve created by intersection of such a plane as well as a right circular cone is known in geometry as a conic section, sometimes known as a conic.
The intersection can be a circle, a ellipse, a hyperbola, or a parabola, depending on the angle the plane makes with the cone.A plane curve, lines, pair of intersection points, or point that connects to or encompasses the point where a plane as well as a cone with two nappes converge.The preceding classes' conics were all of the formula Ax² + Cy² + Dx + Ey + F = 0. These conics are all either vertical or horizontal. For conics that are neither horizontal nor vertical, the B word is needed. Conics take on the generic pattern Ax2 + Bxy + Cy2 + Dx + Ey + F = 0.Thus, teta is a double angle that is used to rotate the x-y coordinate plane into a new x'y' plane in order to graph a rotated conic section.

invest at 6% and still be guaranteed at least $440 in interest per year?
Answers
Answer:
$5000
Step-by-step explanation:
Let x represent the amount invested at 6% interest. Then 7000-x is the amount invested at 7% interest
6% interest = 6/100 = 0.06 in decimal
7% interest = 7/100 = 0.07
Interest earned from depositing x dollars at 6% = 0.06x
Interest earned from depositing 7000-x at 7% = 0.07(7000-x)
Total interest earned would be
0.06x + 0.07(7000-x)
Since this must be at least $440 we get the equation interest as
0.06x + 0.07(7000-x) = 440

0.06x + 0.07 x 7000 - 0.07x = 440
0.06x + 490 -0.07x = 440
-0.01x = 440 - 490
-0.01x = -50
Multiply both sides by -1
==> 0.01x = 50
==> x = 50/0.01 = 5000
So max amount that can be invested at 6% interest = $5000

Mrs. James is on a train traveling 42 m.p.h. As Mrs. James is looking out the window, a freight train traveling at 18 m.p.h. moving in the opposite direction meets and passes her. She noticed it took 8 seconds for the freight train to pass her. The freight train is ___ feet long.
Answers
The freight train is 88.88 feet long.
What is Speed- Distance Formula?Speed = Distance/Time
Distance = Speed X Time
Time = Distance / Speed
As the trains travel in opposite direction then
Relative speed = (42 + 18) = 60 Km/ hr
= 60 x 5/18 = 300/ 18
= 100/9 m/s
So, length of the freight train = 100/9 x 8
= 88.88 feet
Hence, The freight train is 88.88 feet long.
