Answer:

<h2>A. the altitude of a hiker who climbs up a mountain at a constant rate and then rests at the top of the mountain.</h2>

Step-by-step explanation:

The given graph shows a increasing linear behaviour, then it shows a null behaviour.

So, if the graph is about a hiker, then the first part of it expresses that the hiker climbed up, and then rested, because the horizontal part means that there wasn't any move during that period.

Therefore, the right answer is A.

Remember that in a linear graph, horizontal periods of the line means the absence of any ratio of change, so if variables are time and distance, the horizontal part means that the person didn't move during that period.

Now, if the line increases, means that the person was moving forward, that's why the right choice is A.

Answer:

D. the total distance a vehicle travels as it goes up a hill and then maintains a constant rate of speed at the top.

even if the distance increases the graph should rise up.

Question:

aivan3 [116]

Answer:

part A) The scale factor of the sides (small to large) is 1/2

part B) Te ratio of the areas (small to large) is 1/4

part C) see the explanation

Step-by-step explanation:

Part A) Determine the scale factor of the sides (small to large).

we know that

The dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

Let

z ----> the scale factor

$\frac{CB}{C'B'}=\frac{CD}{C'D'}=\frac{BD}{B'D'}$

The scale factor is equal to

$z=\frac{CB}{C'B'}$

substitute

$z=\frac{4}{8}$

simplify

$z=\frac{1}{2}$

Part B) What is the ratio of the areas (small to large)?

<em>Area of the small triangle</em>

$A=\frac{1}{2}(2)(4)=4\ units^2$

<em>Area of the large triangle</em>

$A=\frac{1}{2}(4)(8)=16\ units^2$

ratio of the areas (small to large)

$ratio=\frac{4}{16}=\frac{1}{4}$

Part C) Write a generalization about the ratio of the sides and the ratio of the areas of similar figures

In similar figures the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In similar figures the ratio of its areas is equal to the scale factor squared

The answer is C, but I don't understand why- can anyone tell me?

finlep [7]

Answer:

It's C because we are adding a number on the x but here we skip 5 so it's 6, and on y we add 4 up but since we skipped 5 we add 8 and we get 24. 6, 24. You may say "but SpiritBear, 17 plus eight is 25" and that is true, but if you notice the lowest dot actually starts on 5, not 4 making C right.

Hope this helped and wasn't too confusing
