Which representation of a transformation on a coordinate grid preserves congruence?

Mathematics

Answer:

Rotations, reflections and translations.

Step-by-step explanation:

Rotations, reflections and translations are transformations that preserve the both the angle measurements and the lengths of the sides, so congruence is preserved.

Dilations are transformations that keep the angle measurements, but the side lengths change, so the transformation is similar, not congruent.

If it is asking if that equation is the quadratic formula, then the answer is false. The reason why is that the first 'b' should be negative

The quadratic formula is

$x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$

artcher [175]

Answer:

$91p^{1+3q^{2r}}q^{2r^3}$

Step-by-step explanation:

$(-7pq^2r^3) * (-13p^3q^2r)$

= 91 $p^{1+3q^{2r} }$ * $q^{2r^{3} }$

= $91p^{1+3q^{2r}}q^{2r^3}$

Let U = {5, 10, 15, 20, 25, 30, 35, 40, 45, 50} A = {5, 10, 15, 20, 25} B = {25, 30, 35, 40, 45} C = {10, 20, 30, 40, 50} Find A

Answer:

A∪B = {5, 10, 15, 20, 25, 30, 35, 40, 45}

Step-by-step explanation:

A = {5, 10, 15, 20, 25}

B = {25, 30, 35, 40, 45}

Find A∪B

There are 5 elements in set A

There are 5 elements in set B

A∪B is the combination of all the elements in set A and set B without repeating any

A∪B = {5, 10, 15, 20, 25, 30, 35, 40, 45}

A∪B has 9 elements in it

A ⋂ B = {25}
