Yes. tan and arctan are opposite functions
Answer:

Step-by-step explanation:
Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.
Therefore, we can set up the following equation to find the new balance after 2 years:

Answer: There are 22 whole cheese sandwiches that can be prepared.
Step-by-step explanation:
Since we have given that
Number of slices of bread = 44
Number of slices of cheese = 75
According to question, a cheese sandwich consists of 2 slices of bread and 3 slices of cheese.
So, we need to find the number of whole cheese sandwiches that can be prepared.
Number of sandwich containing only slice of bread is given by

Number of sandwich containing only slice of cheese is given by

As we know that each sandwich should contain both slice of bread and slice of cheese.
So, Least of (22, 25) = 22
Hence, there are 22 whole cheese sandwiches that can be prepared.
A function is an equation that has only one answer for y for every x. This means that:
Set A and Set C are functions because their y values don’t repeat.
Set B is NOT a function because the 2 in the y values repeats twice.

Answer:
About 8 months
Step-by-step explanation:
$60 divided by $8 is 7.5.
Round it up to 8 since you cannot have 7.5 months. Do not round it down because 7 x 8 is 56. Hope this helped.
