Answer:
2. 9
3.12 p^4 - 1/2 p^3 -8p^2 + 2p
Step-by-step explanation:
The degree of the polynomial is found by taking the number of the highest exponent. We add the exponent when there is more than one variable in a term
5m^6n^3 = degree (6+3) = 9
3m^4n^2 = degree (4+2) = 6
So the polynomial is degree 9
Standard from is written from largest exponent to smallest exponent
12 p^4 - 1/2 p^3 -8p^2 + 2p
Answer:
To bring the submarine back to the sea level, it have to move 578 feet upwards
Step-by-step explanation:
Given:
Initially the depth the submarine dives = 657 feet below sea
The height the submarine moves up = 79 feet
To Find :
Change in its depth required to bring the submarine back to the sea level = ?
Solution :
In initially the Submarine will be at the depth of 657 feet below sea
when it goes up, the the depth reduces
657 - 79 = 578 feet
Now the submarine will be the depth of 578 feet
Now the submarine have to move 578 feet upwards to reach the sea level
