Answer:  The correct options are

(2) point D, (3) ray CD, (5) segment CD.

Step-by-step explanation:  We are given to select all the figures that are shown in the diagram.

We can see that in the diagram, a ray starting from the point C and forwarding towards the point D is shown.

So, the diagram shows ray CD.

Since D is a particular point on the ray, so the diagram shows point D.

Since line has no end-points but CD has an endpoint 'C', so the diagram does not show line CD.

Also, since a segment is a portion of a line that has length, so the diagram shows the segment CD.

Finally, since the ray CD is heading towards D, not C. So, the diagram does not show ray DC.

Thus, the correct options are

(2) point D, (3) ray CD, (5) segment CD.

Answer: A ray CD and point D is shown in the diagram.


Step-by-step explanation:

A line↔ has no end points but in the diagram there is a end point at C and arrow after D which means this is also not a line segment because a line segment is a line with two end points .Therefore this is a ray CD→ with end point at C and arrow after point D [ray DC is not correct because D is not an end point in the diagram]. So the diagram is showing point D and a ray CD from the given options.

Ignore the stuff around it ,could someone explain me this?

Answer:

The lines blue and green are perpendicular

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is -1)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

step 1

Find the slope of the blue line

we have the points

(-1,-3) and (0,3)

substitute

m=\frac{3+3}{0+1}

m=\frac{6}{1}=6

step 2

Find the slope of the red line

we have the points

(3,-3) and (4,2)

substitute

m=\frac{2+3}{4-3}

m=\frac{5}{1}=5

step 3

Find the slope of the green line

we have the points

(-4,-1) and (2,-2)

substitute

m=\frac{-2+1}{2+4}

m=-\frac{1}{6}

step 4

Compare the slopes

Blue line ----> m=6

Red line ----. m=5

Green line ---> m=-\frac{1}{6}

so

The slope of the blue line and the green line are opposite reciprocal ( their product is equal to -1)

therefore

The lines blue and green are perpendicular

What is the domain of the function graphed below?
Vlad1618 [11]

Answer:

The domain is the set of x values for which the function resides in.

In this graph, it is unclear as to if the function goes on to infinity, but if it does, the answer is quite easily:

(-2, 4] and [7, ∞)

since the function starts on the left at -2 then continues to the right, with a pause, then indefinitely after.
