Which sequence of transformations proves that shape I is similar to shape II?
A.
a reflection across the x-axis, and then a translation 6 units right
B.
translation 6 units right, and then a 90° clockwise rotation about the origin
C.
a 180° counterclockwise rotation about the origin
D.
a reflection across the y-axis, and then a translation 4 units up
E.
a reflection across the x-axis, followed by a 180° counterclockwise
rotation about the origin, and then a translation 4 units down
Answer:
D
Step-by-step explanation:
The shape I is a reflection across the y-axis, and then a translation 4 units up of shape II. Then the correct option is D.
What is a transformation of geometry?A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.
Reflection does not change the size and shape, but flipped the image.
Translation does not change the size and shape, but changes the location of the geometry.
The shape I is a reflection across the y-axis, and then a translation 4 units up of shape II.
Then the correct option is D.

Chris paid $9.18 for a necklace. This amount includes a sales tax of 8%. What was the cost of the necklace before tax?
Answer:
8.5 or 8.50
Step-by-step explanation:
None for now
"Not putting it here"
The cost of the necklace before tax, for which Chris paid $9.18 including the sales tax of 8% is $8.5.
What is percentage increase ?Percentage increase is the amount added to the initial value in the percentage part.
Chris paid $9.18 for a necklace. This amount includes a sales tax of 8%.
Let the cost of the necklace before tax is x dollars. Now, the 108% of the x is $9.18. Thus,
[tex]x\times\dfrac{100+8}{100}=9.18\\x=\dfrac{9.18\times100}{108}\\x=8.5[/tex]
Hence, the cost of the necklace before tax, for which Chris paid $9.18 including the sales tax of 8% is $8.5.

You have been asked to design a can shaped like right circular cylinder that can hold a volume of 432π-cm3. What dimensions of the can (radius and height) will use the least amount of material?(Hint: The lightest can will be the can with the smallest surface area.)
Answer:
[tex]Height = 12cm[/tex]
[tex]Radius = 6cm[/tex]
Step-by-step explanation:
Given
Represent volume with v, height with h and radius with r
[tex]V = 432\pi[/tex]
Required
Determine the values of h and r that uses the least amount of material
Volume is calculated as:
[tex]V = \pi r^2h\\[/tex]
Substitute 432π for V
[tex]432\pi = \pi r^2h[/tex]
Divide through by π
[tex]432 = r^2h[/tex]
Make h the subject:
[tex]h = \frac{432}{r^2}[/tex]
Surface Area (A) of a cylinder is calculated as thus:
[tex]A=2\pi rh+2\pi r^2[/tex]
Substitute [tex]\frac{432}{r^2}[/tex] for h in [tex]A=2\pi rh+2\pi r^2[/tex]
[tex]A=2\pi r(\frac{432}{r^2})+2\pi r^2[/tex]
[tex]A=2\pi (\frac{432}{r})+2\pi r^2[/tex]
Factorize:
[tex]A=2\pi (\frac{432}{r} + r^2)[/tex]
To minimize, we have to differentiate both sides and set [tex]A' = 0[/tex]
[tex]A'=2\pi (-\frac{432}{r^2} + 2r)[/tex]
Set [tex]A' = 0[/tex]
[tex]0=2\pi (-\frac{432}{r^2} + 2r)[/tex]
Divide through by [tex]2\pi[/tex]
[tex]0= -\frac{432}{r^2} + 2r[/tex]
[tex]\frac{432}{r^2} = 2r[/tex]
Cross Multiply
[tex]2r * r^2 = 432[/tex]
[tex]2r^3 = 432[/tex]
Divide through by 2
[tex]r^3 = 216[/tex]
Take cube roots of both sides
[tex]r = \sqrt[3]{216}[/tex]
[tex]r = 6[/tex]
Recall that:
[tex]h = \frac{432}{r^2}[/tex]
[tex]h = \frac{432}{6^2}[/tex]
[tex]h = \frac{432}{36}[/tex]
[tex]h = 12[/tex]
Hence, the dimension that requires the least amount of material is when
[tex]Height = 12cm[/tex]
[tex]Radius = 6cm[/tex]
