A wooden roller coaster contains a run in the shape of a sinusoidal curve, with a sorios of hills. The crest of each hill is 102 feet above the ground. If it takes a car 1.9 seconds to go from the top of a hill to the bottom (12 feet off the ground), find a sinusoidal function of the form y - Asin (-2) + B that models the motion of the coaster train during this run starting at the top of a hill.

The polynomial function of least degree with a leading coefficient of 1 is: f(x) = x3 + ax2 + bx + c

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212

Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas is (0,-12). the y intercept of the second parabola is (0,-24) what is the positive difference between the a values for the two functions that describe the parabolas
