Answer with explanation:

There are four kind of transformation

1.→Rotation

2.→Reflection

3.→Dilation

4.→Translation

It is given that ,Pre-image and Image are congruent.So, we will remove a transformation called Dilation from the four kind of transformation.

⇒Three transformation are left to choose with,

Rotation , Reflection and Translation.

⇒When we consider Rotation , Orientation is considered that is angle by which pre image is rotated to get image.

⇒While, In Reflection and Translation Orientation is not considered.So,we will use following transformation to show that the two Pre-Image and Image are Congruent.

1. Reflection

2. Translation

Of the isometries, translation is your best tool. The orientation is already correct so rotation is unnecessary, as is reflection.

A survey asked participants whether or not they were vegetarian and how important they thought saving energy was. The two-way ta
blondinia [14]

Answer:

We choose D.

Step-by-step explanation:

The question is which statement is true?

A. 33% of the people surveyed were vegetarian and though saving energy was not important

=> It is wrong because we do not know the total number of people who were surveyed.

B. This statement is wrong, because we also have 26% non - vegetarian though saving energy was not important

C. This statement is wrong, because there are 38% non - vegetarian though saving energy was not important and only 26% non - vegetarian though saving energy was very important

D. True because there are 36% non - vegetarian though saving energy was somewhat important while there are 17% vegetarian think so. Hence, a person who was not a vegetarian was morel likely than a vegetarian to think that saving energy is somewhat important

=> We choose D.

Determine the factors of x2 − 7x − 10.
KIM [24]
Hey there!

We could try to factor this trinomial by splitting up the middle term. We do this by multiplying the coefficient of the first term, 1x², by the constant, –10. This will get us –10. Next, you would have to find two factors of –10 that add up to the coefficient of the middle term, which is –7. 

Factors of –10:

–10 + 1 = –9
–5 + 2 = –3
–2 + 5 = 3
–1 + 10 = 9

As you can see, no factors of –10 add up to –7. Therefore, this trinomial is prime. In other words, you could only get this trinomial by multiplying it by 1 to get itself. 

Hope this helped you out! :-)
