If an image of a triangle is congruent to the pre-image, what is the scale factor of the dilation?
zhannawk [14.2K]

Answer:

1

Step-by-step explanation:

A dilation of .1 or 1/2 would decrease the size. Since the numbers are smaller than zero the triangles would no longer be congruent. A dilation of 10 would increase the size of the triangle, causing the triangles to no longer be congruent. A scale fact of one is equivalent to the same size because 1 does not increase or decrease the size.

Make V the subject of the formula E=mv2/2
Dima020 [189]

Answer:

v = ± \sqrt{\frac{2E}{m} }

Step-by-step explanation:

Given

E = \frac{mv^2}{2} ( multiply both sides by 2 to clear the fraction )

2E = mv² ( divide both sides by m )

\frac{2E}{m} = v² ( take the square root of both sides )

v = ± \sqrt{\frac{2E}{m} }

7^3 times 7^-7 times 7
dusya [7]

Hello there! :)

<u><em>Answer:\frac{1}{343}</em></u>

<u><em>*The answer must have a fraction.*</em></u>

Step-by-step explanation:

Lesson: Zero and Negative Exponents.

Distributive property: a(b+c)=ab+ac

First, you apply exponent rule.

a^b*a^c=a^b^+^c

7^-^3

\frac{1}{7^3}=7^3=7*7*7=343

Final answer: \frac{1}{343}

Hope this helps!

Thanks!

Have a great day!
