<h3>Answer: 5</h3>

Work Shown:

y = -3cos(2pi/5x) is in the form y = A*cos(Bx) where |A| is the amplitude and B helps determine the period T. In this case, B = 2pi/5

T = 2pi/B

T = 2pi/(2pi/5) ... replace B with 2pi/5

T = (2pi/1) divided by (2pi/5)

T = (2pi/1) * (5/2pi)

T = 5 ... note how the '2pi' terms canceled out

So the period is 5

This means that every 5 units on the x axis is when the graph repeats itself.

Irina-Kira [14]
Your answer is X= -1
you have to move terms first to get this
8x-5=2x+1
then collect like terms and calculate sum
8x-2x=1+5
lastly you divide both sides by 6
X=1

there were 936,795 bankruptcy filings in 2018. If there were 310,061 chapter 13 filings, what percent were not chapter 13
Marat540 [252]

66.90% of the total bankruptcy fillings are not chapter 13 fillings.

What is bankruptcy?

This is a situation where the management of a company declares that it could no longer pay its debt obligations as it does have the cash resources to do so.

In this case, the total number of bankruptcy fillings is 936,795, out of which 310,061 are chapter 13 filings

fillings that were not chapter 13=936,795-310,061

fillings that were not chapter 13=626,734

fillings that were not chapter 13 as % of total fillings=626,734/936,795

fillings that were not chapter 13 as % of total fillings=66.90%
