A. find the absolute maximum and minimum values of each function over the indicated interval, and indicate the x-values at which they occur. f(x)=2x^3-2x^2-2x+3; [-1,0]

B. for a certain automobile? M(x)=-.015x^2+1.36x-7.6 represents the miles per gallon obtained at a speed of x miles per hour? 30

c. the price of a ticket to a baseball game rises from $12.00 to $15.00. The quantity of tickets sold falls from 180,000 to 164,000. Calculate the elasticity of demand and state whether it is elastic, inelastic, or unit elsatic. Will revenue rise decline or stay the same?

E. Find the elsasticty of demand (E) for the given demand finction at the indicated values of p. Is the demand elastic, inelastic, or unit elastic at the indicated values and how does this relate to change in price?

q=406-0.03p^2

A. $20

B. $36

the answer is 489

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
