Find the volume v of the described solid s. the base of s is the region enclosed by the parabola y = 2 − 2x2 and the x-axis. cross-sections perpendicular to the x-axis are isosceles triangles with height equal to the base.

Find the roots of the polynomial function f(x) = x^3 + 2x^2 + x

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

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
