What single transformation was applied to triangle A to get triangle B? *
Reflection
Translation
Rotation
Dilation

Dilation is technically the answer, but it is alo a translation because it was moved down. Reflection and rotation do not work here because it asks for a single transformation. This means that is a went to b, then it could only get smaller.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
