Answer:
A. 57 7/9
Step-by-step explanation:
First you multiply 13/3 (the length) by 10/3 (the width). You get 130/9. You then multiply 130/9 (the base) by 12/3 which equals 1560/27.
1560/27 can be simplified to 57.7777778, which in turn converts to 57 7/9.
57 7/9 is the final answer.
Answer: 324/t
Step-by-step explanation:
Suzie paid $324 for t tickers into the rock festival.
The price of each ticket is therefore the total she paid divided by the number of tickets that was bought:
= Total cost / Number of tickets
Total cost = $324
Number of tickets = t
Expression therefore is:
= 324/t

You are going to have to learn something about f(2)
Step One
f(1) = 160
f(1 + 1) = - 2f(1)
f(2) = -2 * 160
f(2) = -320
Step Two
The easiest way is just to keep on going. This is recursive which means you use the last answer to get the next one.
f(3) = -2f(2)
f(3) = -2 * -320
f(3) = 640 Two minus' make a plus.
Step Three
Find f(4)
f(4) = - 2 f(3)
f(4) = -2 * 640
f(4) = - 1280 <<<<<<<<< answer
Alternate Method
f(n) = 160 * (-2) ^ (n - 1)
f(4) = 160 * (-2)^(4 - 1)
f(4) = 160 * (-2)^3
f(4) = 160 * (- 8)
f(4) = -1280
