(a)
Write a function to represent Ryan`s commission.
(a)
Answer to Problem 23PPS
Explanation of Solution
Given:
The points (10, 8), (20, 16), (30, 24), (40, 32), (50, 40), (60, 48) and (70, 56)
Concept Used:
Y − Coordinate of the points are the terms of the sequence.
The arithmetic sequence is
Calculation:
The arithmetic sequence is
Find the common difference:
The sequence is increasing, so the common difference is positive 8.
Write the equation for the nth term of arithmetic sequence with first term 8 and common difference 8.
The difference of x coordinate is:
Function:
So, the function for this arithmetic sequence is
Thus, the function for this arithmetic sequence is
(b)
Graph the function and determine the domain.
(b)
Answer to Problem 23PPS
The domain is {10, 20, 30, 40 …..}
Explanation of Solution
Given:
The points (10, 8), (20, 16), (30, 24), (40, 32), (50, 40), (60, 48) and (70, 56)
Concept Used:
Y − Coordinate of the points are the terms of the sequence.
The arithmetic sequence is
Calculation:
The points to graph are represented by (n, f(n)) .
So, the points are (10, 8), (20, 16), (30, 24), (40, 32), (50, 40), (06, 48), (70, 56),
The domain of the function is the number of 10 − foot 2 x 4 planks cut.
So, the domain is {10, 20, 30, 40 …..}
Thus, the domain is {10, 20, 30, 40 …..}
