Answer:</h2><h3>b. n is odd</h3><h2>
Step-by-step explanation:</h2>
In this problem, we assume that 
is a whole number. The definition of inverse functions tells us that a function 
has an inverse function if and only if the function is one-to-one, that is, if there is no any horizontal line intersecting the graph of at more than one point. This only happens if is odd. This is called the Horizontal Line Test for Inverse Functions. So let's take two examples:
FIRST:
Since n is even, an horizontal line will pass through two points as indicated in the first figure below.
SECOND:
Since n is odd, an horizontal line will pass through just one point as indicated in the second figure below.
Answer:
1300
Step-by-step explanation:
Regular time is 40 hours at 25 dollars per hour
Regular pay is 40*25 = 1000
He worked 48 hours, 48-40 =8, so he worked 8 hours overtime
8 hours at 37.50 overtime pay
8*37.50=300
His total pay is regular pay plus overtime pay
1000+300 = 1300
Answer:
c
Step-by-step explanation:
28+35+21+12=96
Answer:
13/15 of a mile
Step-by-step explanation:
1/5 + 2/3 = total distance
lets set both with a common denominator, in this case, it will be 15
1/5 turns into 3/15 and 2/3 turns into 10/15
3/15 + 10/15 = 13/15
Answer:
600
Step-by-step
Think of 0.2 as just 2, if you were to divide 120 by 2 it is simple to solve, the answer is 60, now go back to 120 ÷ 0.2. The best way to think about this is to take the 0 from 0.2 and add it to your answer of 60 sense 0.2 is in the tenths place.
