1 cm = 20 km
so 3.5 cm would equal : 3.5 * 20 = 70 km <==
Answer:
It has no value.
Step-by-step explanation:
MCan you please explain more so I can give you the answer as a fraction
Y=x^2-5, solve for x
y+5=x^2
x=√(y+5) so
f^-1(x)=√(y+5)
Answer:

Step-by-step explanation:
We are asked to find the measure of each exterior angle of a regular dodecagon.
We know that a regular dodecagon is a 12 sided regular polygon with each side equal.
We know that measure of each angle of n-sided regular polygon can be found using formula:

Upon substituting
in above formula, we will get:


Therefore, the measure of each exterior angle of a regular dodecagon is 30 degrees.
