Answer:

The green triangle is rotated  

✔ 90

degrees to form the blue triangle.

Triangle QRS is rotated  

✔ 180

degrees to form the image triangle JKL.

Step-by-step explanation:

have a nice day because I said so but mostly because you want to

The green triangle is rotated 90 degrees to form the blue triangle. And ΔQRS is rotated 180 degrees to form the image of ΔJKL.

" Coordinate plane is also known as cartesian plane in two dimensional , which is represented by intersection of two axis at 90°, the horizontal axis is known as x-axis and vertical axis is known as y-axis."

According to the given question,

Here all triangles are right angled triangle.

All triangles are perpendicular to the respective axis as per diagram.

Rotation of triangle on coordinate plane from one axis to another forms 90°.

Hence, we conclude that the green triangle is rotated 90 degrees to form the blue triangle. And ΔQRS is rotated 180 degrees to form the image of ΔJKL.

y = 1/5x +7

Step-by-step explanation:

The equation of a line is given by

y = mx+b where m is the slope and b is the y intercept

y =1/5 x + b

Substitute the point into the equation

Answer:  You will need to find the x-intercepts and the vertex

Step-by-step explanation: Use the information in the factors and some formulae.

The x- intercepts are the points where the parabola crosses the x-axis. The x-axis is where y = 0

Set each factor equal to 0 and solve:

x-2=0, so x = +2 and x +4 = 0, so x = -4    (you would plot these if creating the graph)

To find the vertex you need the Vertex Formula: x = -b/2a

b is the coefficient of the x term in the middle of the quadratic equation; you can just do the O and I parts of FOIL to get b:  -2x + 4x = 2x  You know a = 1 because x²  will have the implied (missing)(1).

Put the numbers in the Formula: x = -b/2a   x = -(2)/2(1)  -2/2 = -1  

-1 is the "x-value" of the vertex.  

The y value is the 'c' in the quadratic formula. You get that from the  L part of FOIL   -2 × 4 = -8 .

So, your coordinates for the vertex:  ( -1, -8 )

If you were creating a graph, you would plot that point, then draw the parabola starting there and through the x-intercepts.

Step-by-step explanation:

there could be no red cards inside

A binomial random variable is no since the total number of red cards in the deck is unknown at the start of the experiment.

We have to determine whether the card player selects a playing card from a well-shuffled deck of standard playing cards and sees if the card is a red card or not.

He keeps the card, and then makes another selection and sees if the card is a red card or not.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

He continues this process 10 times and counts the total number of red cards that he selects.

We have to determine if it Is a binomial random variable.

There could be no red cards inside.

Therefore, A binomial random variable is no since the total number of red cards in the deck is unknown at the start of the experiment.

w = 48 : 6

w = 8 inches

l = 2w

l = 2×8inches

l = 16 inches

Answer:

The inverse of the function is

[tex] \sqrt[3]{x - 8} [/tex]

Step-by-step explanation:

To find the inverse of the function we equate f(x) to y

That's

f(x) = y

So we have

[tex]y = {x}^{3} + 8[/tex]

Next interchange the terms x becomes y and y becomes x

That's

[tex] x = {y}^{3} + 8[/tex]

Next make y the subject

That's

[tex] {y}^{3} = x - 8 \\ \\ y = \sqrt[3]{x - 8} [/tex]

Answer:

B. 240

Step-by-step explanation:

We are given an equilateral triangle. By definition, each angle of this triangle is equal to 60 degrees and the sides are all congruent.

We would like to rotate the triangle clockwise so that A maps exactly onto C. Since the internal angles are 60 degrees, when we turn the triangle one time to the right so that B is now at the top, we have rotated the entire figure 60 degrees.

Already, A is actually on C; however, none of the answer choices matches 60 degrees, so we realise that we want a multiple of 60 that will still ensure our triangle maps A to C. We notice that if we rotate the triangle three more times after that first rotation (so that's another 60 degrees, 60 degrees, and 60 degrees), we will obtain a position that is exactly what we want: A is on C!

Thus, the number of angles is 60 + 60 + 60 + 60 = 240.

The answer is B.

~ an aesthetics lover

Answer:

240

Step-by-step explanation:

Since this is an equilateral triangle, we can divide the circle into 3 pieces and the figure will look the same

360/3 = 120

Every rotation of 120, and the figure is identical

120, 240 ,360 will give an identical figure

Since we need to move point A to C we can move it 240 counterclockwise and point A will be at point C
