The answer to what is 1,000 to the power of 4 is 1,000,000
They are both periodic functions that look like waves. They both have a period of 2pi and oscillate between 1 and -1.
For this case we can use the following rule of three:
$ 500 ---------> 100%
$ 400 ---------> x
Clearing x we have:
x = (400/500) * (100) = 80%
Therefore, the percentage of decrease in the rent is:
p = 100-x
p = 100-80
p = 80%
Answer:
a proportion can be used to calculate p is:
p = 100 - ((400/500) * (100))
6 hours and 40 mins which would be 6:45
