Answer:
√52 units
Step-by-step explanation:
The segment MN is the hypotenuse of a right triangle that is 6 units wide and 4 units high. The Pythagorean theorem tells you its length is ...
MN = √(6² +4²) = √(36 +16)
MN = √52
A submarine started at 750 meters below sea level. It rose 50 meters per hour over a 4-hour period. Which expression represents
2 answers:
Answer:
Step-by-step explanation:
We want to model the position of the submarine as a function of time.
Notice that we have a constant amount. The initial depth: 750 meters
Then we have a factor that varies over time. Every hour the submarine ascends 50 meters. therefore as t increases the depth y(t) of the submarine decreases. Then the factor is:
-50t.
Where t represents the time in hours.
Then the equation that represents the new position of the submarine in relation to the level of the sea:
