The total time taken for round trip will be: (f+g)(x) = 14x+11
Step-by-step explanation:
Given
In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.
Hence,
The total time taken for round trip will be: (f+g)(x) = 14x+11

Answer:
17 rows
Step-by-step explanation:
We know that f(x) = 2x² - 10x models the total number of spaces and x models the number of rows.
Since we are given the total number of spaces of 408. We let f(x) = 408
2x² - 10x = 408
Now we solve as a quadratic, subtract 408 to both sides
2x² - 10x - 408 = 0
Divide 2 on both sides
x² - 5x - 204 = 0
We look for terms that multiply to -204 and add to -5.
Those terms are -17 and 12
x² - 17x + 12x - 204 = 0
x(x-17) + 12(x-17)
(x+12)(x-17)
x = -12 x = 17
We can not have -12 rows but we can have 17 rows.
17 rows is the answer.
Answer:
m1 = 72°

Kevin has analyzed the situation well. However, he should also consider the fact that he saved $10 by only purchasing the shirt.Opportunity cost is the cost of the forgone alternative.out of the 3 choices, he only purchased 1 of the choices, the opportunity cost are the other two choices. However, he is still capable of buying the flip-flops costing $10 but he chose not to do so. He should consider it as a savings aside from it being a lost opportunity.
