<h3>Answer:  D)   y+3</h3>

==========================================================

Explanation:

Point A is located at (3,1). Point A' is located at (-5,4)

To move from A to A', we'll do two things:

  • Move 8 units to the left
  • Move 3 units up

The "8 units to the left" portion has us go from x to x-8

The "3 units up" part involves y becoming y+3

So that's how we get the translation rule (x,y) \to (x-8,y+3). The x-8 portion is already filled in for us. The missing part is y+3 which is the final answer (choice D).

Let's try this translation rule on point B to see if we arrive at the proper location of B'

B is at (2,6) which means

(x,y) \to (x-8,y+3)\\\\(2,6) \to (2-8,6+3)\\\\(2,6) \to (-6,9)\\\\

which matches up what the diagram shows. I'll let you verify that the rule also works for point C.

Jade used candle molds, as shown, to make candles that were perfect cylinders and spheres:
Fittoniya [83]

Answer:

The difference in the amount of wax needed is 84.78 in³ (84.78 cubic inches)

Step-by-step explanation:

Given

<em>Cylinder</em>

Radius = 3 inches

Height = 7 inches

<em>Sphere</em>

Radius = 3 inches

Required

The difference in the amount of wax needed to make a candle from each of these molds

The quantity or amount required to make a wax of candle from each molds can be calculated by getting the volume of both molds

The volume of a cylinder is calculated using

<em>V₁ = πr²h</em>

where r and h are the radius and the height of the cylinder, respectively.

r = 3 in and h = 7 in

The volume of a sphere is calculated using

V_{2} = \frac{4}{3}\pi r^3

where r is the radius of the sphere

r = 3 in

Calculating V₁

V₁ = πr²h

V₁ = π * 3² * 7

V₁ = π * 9 * 7

V₁ = π * 63

V₁ = 63π

Calculating V₂

V_{2} = \frac{4}{3}\pi r^3

V_{2} = \frac{4}{3} * \pi * 3^3

V_{2} = \frac{4}{3} * \pi * 27

V_{2} = \frac{108}{3} * \pi

V₂ = 36π

Having calculated the volume of each molds, the difference in the amount of wax needed can then be calculated.

Difference = V₁ - V₂

Substituting 63π for V₁ and 36π for V₂

Difference = 63π - 36π

Difference = 27π

<em>(Taking π = 3.14)</em>

Difference = 27 * 3.14

Difference = 84.78

Hence, difference in the amount of wax needed is 84.78 in³

Musya8 [376]
I believe that the answer would be $9.52, once you calculate both the sales tax and the tip.
