I think the answer is the second one, Tessa wasn't sure how far she would swim during the first class. She would swim 3 laps during the second class. The question is confusing, because the equation s+3 is supposed to be the DISTANCE she swam in 2 classes. The problem didn't specify that distance equals laps, but I think the answer is correct
the degree of the polynomial is 8
The degree of a polynomial is determined by the largest power of an individual term or the sum of the exponents if more than 1 variable
3x² → is degree 2
6xy → is degree 2 ( sum of 1 and 1 )
- 10
→ is degree 5
→ is degree 6
- 10x³
→ is degree 8 ( sum of 3 and 5 )
the term with largest power is - 10x³
The degree of the polynomial is 8

now, we're not including the III and II quadrants, where the cosine has an angle of the same value, but is negative, because the exercise seems to be excluding the negative values of √(2).
Answer:
$11178.20
Step-by-step explanation:
You need to divided the APR/ 12, to know the monthly rate. You have to multiplicate the debt by the monthly rate, the add them. Then substract 471.78 (monthly payment). And repet the procces until the month 36.
You may use an excel sheet to make a table to calculate the payment rmaining.
