Answer:
Step-by-step explanation:
Given
Let x represent the number of tickets, and p the charges
A reduction of 50c gives an increment of 50 tickets.
This gives:
----
Required
Determine the demand function
First, calculate the slope:
So, the equation is:
Hence, the function is:
Answer:
The 13th term is 81<em>x</em> + 59.
Step-by-step explanation:
We are given the arithmetic sequence:
And we want to find the 13th term.
Recall that for an arithmetic sequence, each subsequent term only differ by a common difference <em>d</em>. In other words:
Find the common difference by subtracting the first term from the second:
Distribute:
Combine like terms. Hence:
The common difference is (7<em>x</em> + 5).
To find the 13th term, we can write a direct formula. The direct formula for an arithmetic sequence has the form:
Where <em>a</em> is the initial term and <em>d</em> is the common difference.
The initial term is (-3<em>x</em> - 1) and the common difference is (7<em>x</em> + 5). Hence:
To find the 13th term, let <em>n</em> = 13. Hence:
Simplify:
The 13th term is 81<em>x</em> + 59.
If this makes sense lol... <span>C = 2πr ≈ 2(3.14)(4.3) ≈ 27.02 m. An object travels in a circle of </span>radius 4.3<span>m at constant speed. It takes 1.4 seconds to go around once</span>
812.30/83 = 9.78674698.....
Nearest tenth means one number under decimal place so...
812.30/83 ~ 9.8
Explanation: The 9.7... rounded up to 9.8 because the number after the tenths place (in this case the number after the 7) is greater or equal to 5.
