Answer:
54 ~ see below for explanation
Step-by-step explanation:
you're going to replace n with the 6 since n= 6
so (8+3)6
then you're going to add 8+3 in the parenthesis because of PEMDAS
(9)6
you're going to multiply 6 by 9 since 9 is in parenthesis (a number in parenthesis means multiply)
then you get 54 so the answer would be 54.
Answer:
1. the range of f^-1(x) is {10, 20, 30}.
2. the graph of f^-1(x) will include the point (0, 3)
3. n = 8
Step-by-step explanation:
1. The domain of a function is the range of its inverse, and vice versa. The range of f^-1(x) is {10, 20, 30}.
__
2. See above. The domain and range are swapped between a function and its inverse. That means function point (3, 0) will correspond to inverse function point (0, 3).

3. The n-th term of an arithmetic sequence is given by ...
an = a1 +d(n -1)
You are given a1 = 2, a12 = 211, so ...
211 = 2 + d(12 -1)
209/11 = d = 19 . . . . . solve the above equation for the common difference
Now, we can use the same equation to find n for an = 135.
135 = 2 + 19(n -1)
133/19 = n -1 . . . . . . . subtract 2, divide by 19
7 +1 = n = 8 . . . . . . . . add 1
135 is the 8th term of the sequence.
The height of the cone is 8.59
Four different colours I believe. Because it says each ticket type will be a different colour. Therefor, adult (1), child (2), 1-day (3), 2-day (4).
Hope this was helpful and correct!
B is equal to the number 24.
