It is one hour twenty minutes and thirty-two seconds because there are sixty minutes in an hour and to get how many minutes over an hour 80 is, subtract 60 from 80.
Step-by-step explanation:
2x³ + 14x² + 4x + 28
2(x³) + 2(7x²) + 2(2x) + 2(14)
2(x³ + 7x² + 2x + 14)
2(x²(x) + x²(7) + 2(x) + 2(7))
2(x²(x + 7) + 2(x + 7))
2(x² + 2)(x + 7)
The answer is C.
The distance between the boat and the ocean's floor is 19m

How to get the distance from the ship to the ocean's floor?</h3>
We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.
We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).
Then we use the relation:
Sin(a) = (opposite cathetus)/(hypotenuse).
Replacing the values that we know, we get:
Sin(39°) = d/30m
sin(39°)*30m = d = 18.9m ≈ 19m
The distance between the boat and the ocean's floor is 19m.
