Answer:
The answer is B
Step-by-step explanation:
If you look at the graph, you can look at number of tickets and see that to get 10 tickets, you would get charged 80 dollars not 88, so the answer is B
Answer: 5x - 2
Step-by-step explanation:
So area is length*width, we have the area and length which is 5x^2 + 43x - 18 and x + 9. So we need to divide. First the x, what times x is 5x^2? 5x, x*x is x squared. Then we need to apply the 5x to 9. 5x*9 is 45x, and we can’t do anything to the 18 because 18/5 is a decimal. After that we subtract the new area with the old one. 5x^2 + 43x - 18 minus 5x^2 + 45x which is -2x - 18. Now we divide the -18 with 9 which is -2. Remember the 5x we had from using the x? We put that and -2 together which is 5x-2, and that’s your width. Hope this helped!
The frequency of the periodic function is given by: 0.0796.
<h3>What are the period and the frequency of a function?</h3>
- The period of a function is given by the <u>distance between it's repetitions</u>.
- The frequency of a function is found <u>dividing one by the period</u>.
From the graph, we have that the period is of 4pi hours, hence the frequency is:
f = 1/4pi = 0.0796.
