The second one from the top shows a dilatation.
I think the answer to this question is 10% but I don’t know if it’s right
Answer:
radius and number rotation
For this case we must find the product of the following expression:
By definition of properties of powers and roots we have:
We rewrite the expression using the lowest common index of 6, then:
We rewrite the terms in an equivalent way:
We rewrite the expression using the property mentioned:
We combine using the product rule for radicals:
So:
ANswer:
Option b
C=2πr and x^2+y^2=r^2
r=4 because of the equation (16)^1/2 is 4
C=8π
