Maile is walking around a circular track. if the radius is 100m, how far did she walk if she is 1/3 the way around

1 answer:

7 0

The full length of the circumference is
C = 2πr
C = 2π*100 m ≈ 628.32 m

1/3 that distance is (628.32 m)/3 ≈ 209.44 m

Maile walked about 209.4 m.

Which expression is equivalent to (a^-3 b/a^-5 b3)^-3? Assume a=0, b=0.

$Use:\\\\\dfrac{a^n}{a^m}=a^{n-m}\\\\(a^n)^m=a^{nm}\\\\a^{-n}=\dfrac{1}{a^n}\\\\(ab)^n=a^nb^n$

$\left(\dfrac{a^{-3}b}{a^{-5}b^3}\right)^{-3}=\left(a^{-3-(-5)}b^{1-3}\right)^{-3}=\left(a^{-3+5}b^{-2}\right)^{-3}=\left(a^2b^{-2}\right)^{-3}\\\\=(a^2)^{-3}(b^{-2})^{-3}=a^{2(-3)}b^{-2(-3)}=a^{-6}b^6=\dfrac{b^6}{a^6}$
