Please answer completely. Schools about to finsh and i really need help with my classes. I still have Ap Gov left and Calculus so it would be very helpful if you answer all parts of this. Thank you.

FRQ 1
A graphing calculator is required for the following problem.
10, 10)
(-3, 1)
(3, 1)
Let flx) = log(x? + 1), g(x) = 10 – x², and R be the region bounded by the graphs of f and g, as shown
above.
a) Find the volume of the solid generated when R is revolved about the horizontal line y = 10.
b) Region R is the base of a solid. For this solid, each cross section perpendicular to the x-axis is an
isosceles right triangle with a leg in R. Find the volume of the solid.
c) The horizontal line y = 1 divides region R into two regions such that the ratio of the area of the
larger region to the area of the smaller region is k:1. Find the value of k.

15
_(hours)
R(t)
(railcars)
6
62
80
110
A grain elevator fills each railcar of a train with grain. The number of railcars filled after t hours is given by
a differentiable function R for 0 sts 15. Values of R(t) at various times t are given in the table above.
a) Use the data in the table to approximate the rate at which the number of filled railcars is changing
at time t = 5. Show the computations that lead to your answer. Indicate units of measure.
b) Will the instantaneous rate at which the number of filled railcars is changing at some time t be
equal to the approximation in part (a)? Justify your answer.
c) Use a trapezoidal sum with the four subintervals indicated in the table to estimate * R(t)dt.
Using correct units, interpret the meaning of * R(t)dt in the context of this problem.
d) Determine °R'(t)dt. Using correct units, explain the meaning of the expression in the context
of this problem.
