Which type of transformation is shown in the figure on
the left?
O translation
O reflection
O rotation
O dilation
The answer is reflection

Answers

yea the answer is reflection

The type of transformation that's shown in the figure on the left is; reflection

How does transformation of a function happens?

The transformation of a function may involve any change.

Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs,

A reflection is defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.

When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis such as; if we're seeing it in a mirror.

We will find that its symmetric, thus each point is equidistant from the axis of reflection such that of the image of that point.

The answer is; reflection

Does anyone know how to tell if a graph is inverse

Answers

Step-by-step explanation:

A function f(x) has an inverse, or is one-to-one, if and only if the graph y = f(x) passes the horizontal line test. A graph represents a one-to-one function if and only if it passes both the vertical and the horizontal line tests.

you can tell if the graph is inverse if f(x) passes the horizontal line test ( basically if it touches the line that goes across *horizontally* on the graph) and a graph is a one to one function if and ONLY if it touches both vertical and horizontal lines on the graph

29) (3x + 4) + 50 + 90 = 180 i.e. x = 12

30) (8x + 7) + 35 + 90 = 180 i.e. x = 6

For each gym membership sold, the gym keeps $42, and the employee who sold it gets $8. What is the commission the employee earned as a percentage of the total cost of the gym membership?
followup: If an employee sells a family pass for $135, what is the amount of the commission they get to keep?

Answers

Hence, the commission the employee earned as a percentage of the total cost of the gym membership is [tex]16[/tex] % and the amount of the commission they get to keep is the [tex]16[/tex] % of $[tex]135[/tex] which would be [tex]21.6[/tex] $

What is the percentage?

A percentage is a number or ratio expressed as a fraction of [tex]100[/tex]. It is often denoted using the percent sign, "%".

Here given that,

For each gym membership sold, the gym keeps $[tex]42[/tex], and the employee who sold it gets $[tex]8[/tex].

(1)

Here the full price is [tex]42+8=50[/tex]

So, the commission the employee earned as a percentage of the total cost of the gym membership is

[tex]\frac{8}{50}=16[/tex] %

(2)

Here, the employee sells a family pass for $[tex]135[/tex].

So, the amount of the commission they get to keep is the [tex]16[/tex] % of $[tex]135[/tex] which would be

[tex]\frac{16}{100}[/tex] ×[tex]135=21.6[/tex] $

Hence, the commission the employee earned as a percentage of the total cost of the gym membership is [tex]16[/tex] % and the amount of the commission they get to keep is the [tex]16[/tex] % of $[tex]135[/tex] which would be [tex]21.6[/tex] $

The value of p and q in the right triangle are as follows:

How to find the side of a right triangle?

A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Therefore, the side of a right triangle can be found using trigonometric ratios as follows:

Let's find p and q using the trigonometric ratios.

Hence,

sin 64 = opposite / hypotenuse

opposite side = p

hypotenuse = 34

Therefore,

sin 64 = p / 34

cross multiply

p = 34 sin 64

p = 30.5589975742

p ≈ 30.6 units

Hence,

cos 64 = adjacent  / hypotenuse

cos 64 = q / 34

cross multiply

q = 34 cos 64

q = 14.9046189908

q = 14.9 units

Therefore,

p ≈ 30.6 units

q ≈ 14.9 units

Which function is the inverse of g(x) = [tex]\frac{(x-1)^{3} }{2} -3[/tex]?

Answers

Answer:

third option

Step-by-step explanation:

let g(x)=y

(x-1)³/2-3=y

(x-1)³/2-3/1=y

(x-1)³-6/2=y

(x-1)³-6=2y

(x-1)³=2y+6(find cubic root of both sides)

(x-1)=³√(2y+6)

x=³√(2y+6)+1

Replace y with g for the inverse

Does this graph show a function? why or why not?

Answers

Answer: The graph is a function

It is a function because we do not have two or more red points vertically aligned. In other words, we don't have any red points stacked. This graph passes the vertical line test.

The vertical line test is where we try to find a single vertical line passing through more than one red point. No such vertical line exists, so that's why this graph passes. Passing the vertical line test means we therefore have a function.

A function is where any input x leads to exactly one output. For instance, the input x = 9 leads to the single output y = 28. Similar situations happen with the other x values as well. If we had the two points (9,28) and (9,36), then this wouldn't be a function.

Answer: Yes this is a function

Which expression represents the volume of the composite figure
formed by a hemisphere with radius r and a cube with side length 2r?

Answers

Answer:

A. [tex]r^{3}[/tex]([tex]\frac{2}{3}[/tex][tex]\pi[/tex] + 8)

Step-by-step explanation:

A composite figure is formed by two or more shapes in contact.

Volume of a cube = [tex]l^{3}[/tex]

where l is the length of its sides.

Given that l = 2r, then;

volume of the cube = [tex](2r)^{3}[/tex]

                                 = 8[tex]r^{3}[/tex]

volume of the cube = 8[tex]r^{3}[/tex]

For a hemisphere, volume = [tex]\frac{2}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]

Also,

volume of the hemisphere = [tex]\frac{2}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]

So that,

volume of the composite figure = volume of the cube + volume of the hemisphere

                                                 = 8[tex]r^{3}[/tex] + [tex]\frac{2}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]

                                                 = [tex]r^{3}[/tex](8 +  [tex]\frac{2}{3}[/tex][tex]\pi[/tex])

volume of the composite figure =  [tex]r^{3}[/tex]([tex]\frac{2}{3}[/tex][tex]\pi[/tex] + 8)

Answers

Answer:

The proof is shown below.

Step-by-step explanation:

Given: B is mid point of AC and C is mid-point of BD.

To prove: AD=3AB

It is given that B is mid-point of AC.

⇒ AB = BC               ...(1)

Also, C is mid-point of BD.

⇒ BC = CD               ...(2)

From (1) and (2),

AB = BC = CD

Now, AD = AB + BC + CD

⇒ AD = AB + AB + AB             (∵ AB = BC = CD )
