Answer:
3x^3 - 11x^2 + 93x - 105
Step-by-step explanation:
(x+5) (x-9) (x+1) (3) FOIL (First, Outside, Inside, Last)...
x^2 - 9x + 5x - 35 (3x+3) Multiply
3x^3 + 3x^2 - 27x^2 - 27x + 15x^2 + 15x - 105x - 105 Combine Like Terms...
3x^3 - 11x^2 + 93x - 105
Answer:
s = 28.09 m/s
Step-by-step explanation:
Given that,
The equation that gives the height of the largest ocean waves when the wind speed is s knots is given by :

We need to find the wind speed if the largest waves are 15 feet high.
Put h = 15 feet in the above equation as follows :

So, the speed of the wind is 28.09 m/s.
