- Roller coaster A portion of a roller coasters tracks can be modeled by the polynomial function f(x)=0.0001(x3600x2+90,000x), where 0x400.f(x) represents the height of the roller coaster in feet and x represents the horizontal distance in feet. a. Find the height of the roller coaster when x=100 yards. b. Find the values of x on the interval [0,400] at which the height of the roller coaster is 0 yards.arrow_forwardFill in the blanks.

- Social Security Assets The table gives actual and projected year end assets in Social Security trust funds, in trillions of current dollars, where Year represents the number of years since 2000. Source: Social Security Administration. The polynomial function defined by f(t)=0.0000329t30.00450t2+0.0613t+2.34 models the data quite well. a. To verify the fit of the model, find f(10),f(20), and f(30). b. Use a graphing calculator with a command such as nDeriv to find the slope of the tangent line to the graph of f at the following t-values: 0,10,20,30, and 35. c. Use your results in part b to describe the graph of f and interpret the corresponding changes in Social Security assets.
