The answers are option C) segment and option D) ray

<u>Step-by-step explanation</u>:

Line :

  • A line has arrow mark in the two ends. So, the diagram is not a line.

Point :

  • A point represents particular spot as a small dot. So, the diagram is not a point.

Segment :

  • It is a piece of line that has two end points. This part of line is called line segment and it is shown in the picture. option C is correct.

Ray :

  • A ray is a line with one endpoint and the other end extends with an arrow mark. So, the option D is also correct.

The point Z(5, -3) is rotated 270° clockwise around the origin. What are the coordinates of the resulting point, Z′?
g100num [7]

Answer:

(3, - 5 )

Step-by-step explanation:

Under a clockwise rotation about the origin of 270°

a point (x, y ) → (- y, x ), hence

Z(5, - 3 ) → Z'(3, - 5 )

Is this the relation R:={(2,1),(3,1),(5,5),(7,5)} a function?
fredd [130]
<h3>Answer: Yes, it is a function</h3>

This is a function because there are no x values that repeat.

If we had repeated x values, then this would mean a certain input x leads to multiple outputs y, and that would not make it a function.

For instance, if we had (2,1) and (2,2) at the same time, then the input x = 2 leads to multiple outputs y = 1 and y = 2 at the same time. A function would not be possible in this example.

A function is only possible if any input x leads to exactly one output y. It is possible for y to repeat itself and still have a function.

Pip was thinking of a number. Pip halves the number and gets an answer of 87.2. Form an
jeyben [28]

Answer:

x/2=87.2

Step-by-step explanation:

Pip was thinking of a number - Let's call this number x

Pip halve the number - So half of x = x/2  (or 1/2 x)

And gets an answer of 87.2  - x/2=87.2

So your equation would be x/2=87.2

I hope this helps :)

Choose the correct simplification of 8x2(4x 2x2 − 1). (5 points) group of answer choices 32x4 − 16x3 8x2 32x4 16x3 − 8x2 16x4 −
nekit [7.7K]

The second option is the correct answer

16x^{4}+40x^{3} -24x^{2}

The expression given to us is:

8x^{2} (5x+2x^{2}-3 )

Herein, we can simplify it by opening up the bracket and multiplying each term inside the bracket by the term which is outside the bracket.

Thus, we get:

8x^{2} (5x+2x^{2}-3 )=8*5x^{2+1} +8*2x^{2+2}-8*3x^{2}

40x^{3} +16x^{4}-24x^{2}

Rearranging the above expression in descending order of power we get:

16x^{4}+40x^{3} -24x^{2}

From the given options we can see this is the second option. Hence the second option is the correct answer.
