Two parallel lines are 7 units apart. If you

Mathematics
1 answer:
Sedaia [141]3 years ago
4 0

Answer:

14 units

Step-by-step explanation:

We apply the <em>Theorem of reflection over parallel lines.</em>

Theorem: The composition of two reflections over parallel lines that are h units apart is the same as a translation of 2h units.

Given that the two parallel lines are 7 units apart

h=7 units

2h= 2 X 7 =14 units

Therefore, the preimage and the final image will be 14 units apart.

Can someone help me please i didnt learn this
OLga [1]

Answer:

1.) Exponential Growth

2.) Exponential Decay

3.) Exponential Growth

4.) Exponential Decay

Step-by-step explanation:

<u>1.) </u><u><em>f (x) </em></u><u>= 0.5 (7/3)^</u><u><em>x</em></u>

            ↓

always increasing

<u>2.) </u><u><em>f (x) </em></u><u>= 0.9 (0.5)^</u><u><em>x</em></u>

<em>             </em>↓

always decreasing

<u>3.) </u><u><em>f (x) </em></u><u>= 21 (1/6)^</u><u><em>x</em></u>

            ↓

always increasing

<u>4.) </u><u><em>f (x) </em></u><u>= 320 (1/6)^</u><u><em>x</em></u>

<em>          </em>   ↓

always decreasing

<u><em>EXPLANATION:</em></u>

It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.

Which glide reflection describes the mapping ABC DEF​
almond37 [142]

Answer:

1. Reflect ABC about the line AC and then translate 1 unit to the right.

2. Translate ABC 1 unit to the right and then reflect it about the line AC.

Step-by-step explanation:

We are given that,

ABC is transformed using glide reflection to map onto DEF.

Since, we know,

'Glide Reflection' is the transformation involving translation and reflection.

So, we can see that,

ABC can be mapped onto DEF by any of the following glide reflections:

1. Reflect ABC about the line AC and then translate 1 unit to the right.

2. Translate ABC 1 unit to the right and then reflect it about the line AC.

Hence, any of the two glide reflection will map ABC onto DEF.
