Answer:
y = -3x²
Is a concave down with a maximum turning point at (0,0)
y = ⅓(x²)
Is a concave up with a minimum turning point at (0,0)
B is the 3/4 = .75 and 5/8 = .625
The median is 89 because you need to find the average and then divide by 2 to get you answer.

Answer:
143.1 ft
Step-by-step explanation:
Assuming the rope is tied to the boat, and that the geometry can be modeled by a right triangle, the Pythagorean theorem is helpful.
150² = 45² + d²
d = √(150² -45²) = √20475 ≈ 143.1 . . . . feet
The horizontal distance between the man and the boat is about 143.1 feet.
