The sequence of transformations used to obtain figure A'B'C'D'from figure ABCD are a reflection across the y-axis followed by a horizontal translation 1 unit right
Complete questionFigure ABCD is transformed to figure A'B'C'D', as shown below: (see attachment)
Which of the following sequences of transformations is used to obtain figure A'B'C'D'from figure ABCD?
How to determine the transformation?From the attached figure, we can see that:
ABCD and A'B'C'D' are on either sides of the y-axis.
This means that ABCD is first reflected across the y-axis.
ABCD is 2 units from the y-axis, while A'B'C'D' is 1 unit from the y-axis.
This means that the reflection is followed by a translation.
The unit of translation is:
Unit = 2 - 1
Evaluate
Unit = 1
1 represents a right translation
Hence, the sequence of transformations are a reflection across the y-axis followed by a horizontal translation 1 unit right

Answer:
the length of the fence = 420 ft
The total area = 8000 ft²
Step-by-step explanation:
the fence has the same length as the perimeter of the rectangle
then
the length of the fence = 2×(160+50) = 420 ft
………………………………………………………………
The total area enclosed by the fencing = the area of the rectangle
Then
The total area = 160×50 = 8000 ft²
Answer:
see explanation
Step-by-step explanation:
the perimeter (P) of a rectangle is calculated as
P = 2(length + width)
= 2(160 + 50)
= 2 × 210
= 420 ft ← amount of fencing needed
the area (A) of a rectangle is calculated as
A = length × width = 160 × 50 = 8000 ft²

How to get the length of the other side in terms of x and p?
For a rectangle of length L and width W, the perimeter is:
P = 2*(L + W).
Here we know that the perimeter is p, so P = p, and let's say that the width is x.

m = (y2 - y1)/(x2 - x1) = [-2 - (-6)]/[4 - (-6)] = 4/10 = 2/5
y = 2/5 x + b

If a person is chosen at random in this survey, what is the P(decaf or sugar)?
HELP PLS!
The value of the probability P(decaf or sugar) is 0.41
How to determine the probability?From the table, we have:
P(decaf) = 0.05 + 0.08 + 0.09 = 0.22
P(sugar) = 0.19 + 0.08 = 0.27
P(decaf and sugar) = 0.08
The required probability is:
P = P(decaf) + P(sugar) - P(decaf and sugar)
This gives
P = 0.22 + 0.27 - 0.08
Evaluate
P = 0.41

What is a scatter plot?Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both the co-ordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.
We have a scatter plot shown in the table:
1) As we can see in the scatter plot all data are within 3 standard deviations of the mean:
Standard deviation = SD
6SD(x) = 40
SD(x) = 40/6 = 6.67
6SD(y) = 20
SD(y) = 20/6 = 3.37
2) Slope of the line:
= SD(x)/SD(y) = (20/6)/(40/6) = 1/2 = 0.5
3) It is plausible to take the slope of the line as 0.5 because the slope of the line is the ratio of the change in y to the change in x.
Thus, the plausible values for the SD(x) are 6.67 and for SD(y) is 3.37, and the slope of the line is 0.5.

Step-by-step explanation:
functions :- an expression, rule or law that defines relationship between one variable and another variable. When a certain condition is fulfilled, then the result is corresponding to that condition.
h(-1)In the function it is given that when x∈(-2,-1] then we get -1. Now here x=-1 satisfies the given condition. So, the answer will be -1.
h(-0.5)In the function it is given that when x∈(-1,0] then we get 0. Now here x=-0.5 lies in the range (-1,0]. So, the answer is 0.
h(1)In the function it is given that when x∈(0,1] then we get 1. Clearly, x=1 satisfies this range of values. So, we get 1.
Hence, the Answer is h(-1) = -1, h(-0.5) = 0 and h(1) = 1.

Which line is perpendicular to a line that has a slope of -5/6?
Answer:
Line LM
Step-by-step explanation:
First, we need to know what the slope is of a line that would be perpendicular to a line with a slope of -5/6. To find this, we take the reciprocal and multiply it by -1. Therefore, the line we are looking for needs to have a slope of 6/5.
Based on the fact that the slope is positive, we can eliminate lines PQ and JK as they have a negative slope. This leaves us with lines LM and NO.
To find out whether or not it is between LM and NO, you could eyeball it by looking at the graph and simply counting which might be faster if you understand how to do that (rise/run), or you can use the pair of coordinates given to you on each line to calculate for slope.
Line LM - [tex]\frac{-3-3}{-5-0}=\frac{-6}{-5}=\frac{6}{5}[/tex]
Line NO - [tex]\frac{-5-0}{-6-0}=\frac{-5}{-6}=\frac{5}{6}[/tex]
Based on this, we know that line LM is perpendicular to a line that has a slope of -5/6.

-------------------------------------------------------------------------------------------------------------
Given: [tex]\textsf{The image provided with 2 angles and one side}[/tex]
Find: [tex]\textsf{Solve for the unknown side of x}[/tex]
Solution: In order to determine the length of x we need to use some trigonometric functions. Using Soh Cah Toa we can see that we can either use 30 degrees or 60 degrees. We will stick to 60 and we can see that the opposite side is 3 and the hypotenuse is x meaning that we need to use sin. Plug in the values and solve for the unknown.
Plug in the values
[tex]\textsf{sin(30) = }\frac{\textsf{opposite}}{\textsf{hypotenuse}}[/tex][tex]\textsf{sin(30) = }\frac{\textsf{3}}{\textsf{x}}[/tex]Multiply both sides by x
[tex]\textsf{sin(30) * x = }\frac{\textsf{3}}{\textsf{x}}\textsf{ * x}[/tex][tex]\textsf{sin(30) * x = 3}[/tex]Divide both sides by sin(30)
[tex]\textsf{sin(30) * x}*\frac{1}{\textsf{sin(30)}}\textsf{ = 3}}*\frac{1}{\textsf{sin(30)}}[/tex][tex]\textsf{x = 3}}*\frac{1}{\textsf{sin(30)}}[/tex]Simplify
[tex]\textsf{x = 3}}*\frac{1}{\textsf{0.5}}[/tex][tex]\textsf{x = 6}[/tex]Therefore, the value of the unknown variable x is 6 units.

2. The Weimer Corporation wants to accumulate a sum of money to repay certain debts due on December 31, 2030. Weimer will make annual deposits of $180,000 into a special bank account at the end of each of 10 years beginning December 31, 2021. Assuming that the bank account pays 6% interest compounded annually, what will be the fund balance after the last payment is made on December 31, 2030?
Based on the annuities calculated, he should choose option 1.
How to calculate the annuities?Present value = $35,000 + (Annuity amount * Present value of an ordinary annuity of $1)
= $35,000 + ($9,400 * (5%,6))
= $35,000 + ($9,400 * 5.07569)
= $35,000 + 47,711
= $82,711
Present value = (Annuity amount * Present value of an ordinary annuity of $1)
= $17,700 * (5%,6)
= $17,700 * 5.07569
= $89,840
Alex should choose Option 1
Future value annuity = Annuity amount * Future value of an ordinary annuity of $1
= $180,000 * (6%,10)
