The unit rate of the bicyclist's speed is found by dividing the distance covered (1/5 mile) by the time spent (1/65 hour). The result is 13 miles per hour.
In this problem, you're asked to find a unit rate. A unit rate is a rate in which the second term is 1. So, to find a unit rate, you divide the first term with the second term.
In this case, the bicyclist's rate is 1/5 mile in 1/65 hour. If you divide 1/5 by 1/65, you find the rate of bicycle speed per 1 hour, which is the unit rate:
1/5 miles divided by 1/65 hours = (1/5) * (65/1) = 13 miles/hour
So, the bicyclist's unit rate is 13 miles per hour.

g(x)=-25+x^2
Answer:
g(x) = (x + 5)(x - 5).
Step-by-step explanation:
g(x) = -25 + x^2
g(x) = x^2 - 25
This is the difference of 2 squares so:
g(x) = (x + 5)(x - 5) (answer).
B) (A' ∩ B')
C) (A ∪ B)
D) A' ∪ B'
The expression represents the union of not A and not B will be A' ∪ B'. Then the correct option is D.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression represents the union of not A and not B mathematically as,
A' ∪ B'
Then the correct option is D.
