Replace x = 3 into <span>6/x + 2x^2
</span>6/x + 2x^2
=6/3 + 2 (3)^2
= 2 + 2(9)
= 2 + 18
= 20
The rationalized form of 1+ √2/1-√2 is -2√2-3
Given : A submarine descends at a rate of 2.6 kilometers per hour.
If the ocean floor is 6.24 kilometers below sea level,
To Find : how long will it take the submarine to descend to the ocean floor?
Solution:
The submarine descends at a rate of 2.6 kilometers per hour.
Speed = 2.6 km/hr
The ocean floor is 6.24 kilometers below sea level,
Distance to be covered = 6.24 km
Time= Distance / Speed
= 6.24 / 2.6
= 2.4 hr
The submarine will take 2.4 hrs to descend to the ocean floor
