Answer: 60480
Step-by-step explanation:
Given : The number of empty seats in a theater = 9
The number of customers need to find places to sit =6
Since order matters here, so we use permutations
The permutations of n things taking r at a time is given by :-
Then, the number of ways to arrange 6 seat in 9 seats :-
Hence, the number of ways to arrange 6 seat in 9 seats = 60480
Answer:
Step-by-step explanation:
A way to find the inverse function is to swap the x and y (f(x)) in the equation.
We can check that it is an inverse function by using a property of inverse functions:
If we plug in the f(x) function into the variable x of the inverse function, we should end up with x
It checks out!
The answer is D. This is because when you take 10.65 and subtract 9.95 from it you get 0.07. If you take this number and continuously add to 9.95 you get the numbers provided in the chart. We'll also notice that the 0.07 is only added after 10 minutes of talking (10,20,30,etc.).
The equation of the line is y = -2/3(x) - 4
