After 3 minutes, a submarine had descended to −320 feet.
This means that . So
After 8 minutes, the submarine had descended to −420 feet.
This means that . So
From the first equation:
So
And
So
Answer:
Step-by-step explanation:
The attachment shows the steps.
quotient: 10x +16
remainder: 28x^2 +10x +22
_____
Polynomial long division is easier than numerical long division because you only need to examine the first terms to determine the quotient term.
The first quotient term is 10x^4/x^3 = 10x.
The second quotient term is 16x^3/x^3 = 16.
When the leading dividend term is lower degree than the divisor, that dividend is the remainder.
