Answer:
x = 128
Step-by-step explanation:
Adjacent angles - Angles right next to each other. They share a common vertex
Vertical angles - angles that are vertically aligned with each other.
The angle that has a measure of 128 degrees and x are vertical angles
If you didn't know vertical angles are congruent so because one angle equals 128 degrees the other equals 128 degrees
x = 128
Answer:
75x² + 10x - 2
Step-by-step explanation:
Substitute x = 5x into f(x), that is
f(5x) = 3(5x)² + 2(5x) - 2
= 3(25x²) + 10x - 2
= 75x² + 10x - 2
Answer:
$12.25
Step-by-step explanation:
$88.20 / 7.2 hours
$12.25 / hour
If these permutations were in a line, then the equation would be n!. But since we are dealing with a circle, it's a little bit different, given that there is no specific beginning or end. This means that <span>you could rotate the circle around n different ways and still have the same circular permutation. Thus, this would be the expression you are looking for:
n!/n, which can be simplified as (n-1)!
The correct answer is the second option.</span>
