Identify the figure that portrays the translation of the given preimage as indicated by the direction arrow.
Preimage: (first photo)
The parallelogram will translate along the arrow and reach the head of the arrow.
The translation is a category of motion in which one body moves along towards a particular direction and reaches a particular point.
In translation, the rotational motion is not present. Also, the translational motion is a one-dimensional motion.
In the given figure, the parallelogram is present at the tail of the arrow.
The arrow depicts the direction of the translational motion.
So, the parallelogram will reach the end of the arrow as shown in the picture present in the attachment.

A sample of 50 11th graders were asked to select a favorite pattern out of 6 choices. The data list below shows what their favorite color patterns were, and the accompanying frequency table and bar graph represent these data. In the bar graph, the height of the blue-gray bar is 4, the height of the green bar is 9, and so on.
Suppose that, rather than being just a bar graph, the display you see above is a relative frequency bar graph. The vertical axis of the graph will be marked off in percentages, from 0 percent up to 30 percent. What will be the height of the green bar?
A.
15
B.
25
C.
9
D.
18
Answer:
D 18
Step-by-step explanation:
100% = 50 (all students)
1% = 100%/100 = 50/100 = 1/2 = 0.5
we get any percentage for any number by dividing the number by 1% (0.5) to see how often it fits in.
there are 9 votes for green.
9/ 0.5 = 18%

The differentiation of the function y = sin(2 sin⁻¹x) is; dy/dx = d√(1 - y²)]/(√1 - x²)
How to differentiate functions?
1) We want to differentiate the function;
[tex]\frac{\sqrt{x + 1} + \sqrt{x - 1}}{\sqrt{x + 1} - \sqrt{x - 1} }[/tex]
Differentiating this gives;
dy/dx = [tex]\frac{[(\frac{1}{2\sqrt{x + 1}} - \frac{1}{2\sqrt{x - 1}}) * \sqrt{x + 1} + \sqrt{x - 1}]}{(\sqrt{x + 1} - \sqrt{x - 1})^{2} }[/tex]
That can be simplified to get;
dy/dx = [tex]\frac{\sqrt{x + 1} + \sqrt{x - 1} }{(x - 1)\sqrt{x + 1} + (-x - 1) \sqrt{x - 1}}[/tex]
2) We want to differentiate the function;
y = sin(2 sin⁻¹x)
Differentiating the function gives;
dy/dx = [2cos(2 sin⁻¹x)]/√(1 - x²)
We know from trigonometric identity that;
cos²x = 1 - sin²x
Thus;
1 - sin²(2 sin⁻¹x) = cos²(2 sin⁻¹x)
But sin²(2 sin⁻¹x) = y²cos²(2 sin⁻¹x)
Thus; √(1 - y²) = cos(2 sin⁻¹x)
dy/dx = d√(1 - y²)]/(√1 - x²)

B. 8 pack of granola bars for $2.72
C. 9 pack of granola bars for $2.97
D. 6 pack of granola bars for $1.92
Answer:
A or 0.31 per bar
Step-by-step explanation:
To solve this problem we want to find the price of the singular bar and find the cheapest one. So we will divide the amount of bars by the total price, so option A will equal 0.31, option B will equal 0.34, option C will equal 0.33, and option D will equal 0.32. The cheapest per bar price would be a or 3 pack of granola bars for 0.93 cents.
Helen has 48 cubic inches of clay to make a solid square right pyramid with a base edge measuring 6 inches. a solid right pyramid with a square base has a base edge measuring 6 inches. which is the slant height of the pyramid if helen uses all the clay?
The slant height of the pyramid will be 5 inches.
Given Information and Formula Used
Volume of the clay = 48 cubic inches
Edge of the square base of the pyramid, a= 6 inches
Volume of the pyramid = (1/3) × Base Area × Height
Pythagoras Theorem, l² = x² + h²
Here, l is the hypotenuse, x is the base and [tex]h[/tex] is the height in a right angle triangle.
Calculating the Height, h of the Pyramid
Volume of the pyramid = Volume of the clay
Volume of the pyramid, V= 48 cubic inches
Base Area of the pyramid, B = a²
⇒ B = 6² square inches
⇒ B = 36 square inches
∵ V = (1/3)×B×H
[tex]\frac{1}{3}*36*h = 48[/tex]
∴ [tex]h = \frac{48*3}{36}[/tex]
⇒ h = 4 inches
Calculating the Slant Height, l of the Pyramid
Applying Pythagoras Theorem to determine the slant height,
l² = x² + h²
Here, we have x=a/2
[tex]l^{2} = \frac{a^{2} }{4} + b^{2}[/tex]
[tex]l^{2} = \frac{6^{2} }{4} + 4^{2}[/tex]
[tex]l = \sqrt{9+16}[/tex]
[tex]l=\sqrt{25}[/tex]
l =5 inches
Thus, the slant height of the solid right pyramid with a square base made by Helen is 5 inches.
