Rectangle ABCD is rotated by 90 degrees clockwise about the origin and
then translated 3 units left and 2 units down to form A'B'C'D'.
What is the length in units of line segment A’B’ in the resulting figure
The length in units of the line segment A'B' in the resulting figure is the same as the length of line segment AB in the previous rectangle.
Translation of shapes in the Cartesian planeForm the task content;
It follows that the initial rectangle A is only translated and hence, the size of each of its sides remains constant.The translation which occurs on the rectangle only shifts the whole rectangle leftward and downward and hence, each line segment in the rectangle still retains its length.

Final Amount 10,400
Initial investment ?
Interest Rate 2%
Time (Years) 4
How do i find the initial investment
Answer:
$9629.63
Step-by-step explanation:
I assume this is simple interest.
The formula for simple interest is
F = P(rt + 1)
where F = future value,
P = present value
r = annual interest rate
t = number of years
10,400 = P(0.02 × 4 + 1)
10,400 = 1.08P
10,400/1.08 = P
9,629.63 = P
Answer: $9629.63
Each of these labelled bags contains two apples.
One bag contains two green apples, another two red apples and the third one green and one red apple.
All three bags are mislabelled. You may look at only one apple from any one of the bags.
Which bag should you select from to be sure you can determine the content of all three bags?
- Bag 1 ?
-Bag 2 ?
-Bag 3 ?
Step-by-step explanation:
all bags are mislabeled. that means, whatever is written on either of the 3 bags, is wrong.
so, the bag labeled "green" is NOT the one with 2 green apples. the one labeled "red" is NOT the one with 2 red apples.
and - my favorite - the one labeled "red/green" is NOT the one with the mixture.
so, we pick one apple from the bag that is currently (mis-)labeled as "red/green".
as it cannot be the mixed bag, it must be one of the pure color bags.
whatever color shows up, we know this is the bag with 2 apples of that color.
then the bag that was labeled with that color must be the other pure color (if it were the mixed bag, it would mean that the third bag was labeled correctly, which is not the case). and then the third bag is the mixed one.
for example :
we get a red apple in our first pick.
so, the bag, that was originally (but wrongly) labeled as "red/green" gets the label "red".
then the bag with the original (but again wrong) label "green" gets now the label "red".
and the third bag with the original (but wrong) label "red" gets the "red/green" label.
if the first apple is green, then the same principle just with reversed colors applies.

ONLY #14 but you need to look at the the question (not the answer) in 13 to answer 14
14. Write but do not evaluate the integral which can be used to find the volume which results when region R in problem 13 is revolves around the line x=4
Answer:
[tex]\displaystyle V = \pi \int_0^{1.835}\left[ 4 - y^2\right]^2 - \left[ 4-\sqrt{4(y+1)}\right]^2\, dy[/tex]
Step-by-step explanation:
We can use the washer method. Because the axis of revolution is vertical, our representative rectangle is horizontal. Recall that:
[tex]\displaystyle V = \pi \int_a^b \left[ R(y)\right] ^2 - \left[r(y)\right]^2 \, dy[/tex]
Solve each equation as a function of y:
[tex]\displaystyle \begin{aligned} y & = \sqrt{x} \\ \\ x_1 & = y^2\end{aligned}[/tex]
And:
[tex]\displaystyle \begin{aligned} y & = \frac{1}{4}x^2 - 1 \\ \\ x_2 & = \pm\sqrt{4(y+1)} \\ \\ & = \sqrt{4(y+1)}\end{aligned}[/tex]
The outer radius R is simply (4 - x₁) and the inner radius r is (4 - x₂). The point of intersection is (3.368, 1,835), so our limits of integration are from y = 0 to y = 1.835.
Therefore, the integral that represents the region being revolved around
x = 4 is:
[tex]\displaystyle V = \pi \int_0^{1.835}\left[ 4 - y^2\right]^2 - \left[ 4-\sqrt{4(y+1)}\right]^2\, dy[/tex]

Choose the conjecture that describes how to find the 6th term in the sequence 4, 20, 36, 52, ….
The sequence 4, 20, 36, 52, Required 6th term is 84.
What is sequence?A sequence is an enumerated group of objects in mathematics where repetitions are permitted and order is important. Similar to a set, it has members (also called elements, or terms). The length of the sequence is the number of elements (possibly infinite). In contrast to a set, the same elements can appear more than once in a sequence at various positions, and unlike a set, the order is important. The formal definition of a sequence is a function from natural numbers to the elements in each position. An indexed family, which is a function from any index set, can be thought of as a generalisation of the idea of a sequence.
For instance, the letters (M, A, R, Y) are arranged with M coming first and Y coming last.
Given, sequence is an arithematic sequence with common difference 16 and first term 4.
So,
6th term = first term + 5 * common difference
= 4 + 5 * 16
= 84
Hence, the required 6th term is 84.

What are the coordinates of A' and B' when AB is reflected in the y-axis? Show your work or explain how you got your answer.
Answer:
Step-by-step explanation:
What is the rule for a reflection across the Y axis? The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same
Answer:
A'(-2, 5)
B'(-6, 3)
Step-by-step explanation:
When a point is reflected in the y-axis, the image is as far from the y-axis on the other side as the original point is on this side. That is, the y-axis is halfway between the original point and its image. The x-coordinate of a point measures how far from the y-axis it is, so reflection in the y-axis changes the sign of the x-coordinate:
(x, y) ⇒ (-x, y) . . . . . reflection in the y-axis
__
A(2, 5) ⇒ A'(-2, 5)
B(6, 3) ⇒ B'(-6, 3)

The unit rate is:
Answer:

Step-by-step explanation:
I assume you want miles per gallon
3/10 mile / 1/4 gallon = 3/10 * 4/1 = 12/10 = 1.2 miles per gallon
if you want gallons/mile
1/4 gallon / 3/10 mile = .8333 gallon/mile

Was I supposed to put a greater number than 10 on top of the 4? What am I supposed to do and why?
Answer:
So looking at the expression that was given to us, we know that we must solve for g. In order to solve for g we need to make sure that g is alone on one side of the expression. In this example, we need to multiply both sides by 4 to get rid of the fraction on the left and in effect we would multiply 12 by 4 also.
[tex]\frac{g}{4} > 12[/tex]
[tex]\frac{g}{4}*4 > 12*4[/tex]
[tex]g > 48[/tex]
Therefore, our final answer is [tex]g > 48[/tex]
Hope this helps! Let me know if you have any questions

A goal is to get at least 15% of daily calories from polyunsaturated fats found in various nuts, oils, and fish. 1 serving of walnuts (about 15 pieces) has about 21 grams of polyunsaturated fat. Each fat gram has 10 calories. On a 2,100-calorie diet, about what percent of daily calories does 1 serving of walnuts provide?
Using the percentage concept, it is found that 1 serving of walnuts provides 10% of daily calories.
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
In this problem, one serving has 21 grams, each with 10 calories, hence the number of calories is given by:
C = 21 x 10 = 210 calories.
Hence, out of a 2,100 calorie diet, the percentage is given by:
[tex]P = \frac{210}{2100} \times 100\% = 10\%[/tex]
