For q (x) = (-4x²+4x−1)/ (x²+2) (a) Identify the horizontal asymptotes (if any). (b) If the graph of the function has a horizontal asymptote, determine the point (if any) where the graph crosses the ho asymptote(s). Separate multiple equations of asymptotes with commas as necessary. Select "None" if applicable. The graph has no horizontal asymptotes. O The graph has at least one horizontal asymptote. Equation(s) of the horizontal asymptote(s): Crossover point(s):

You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately o = 20.8. You would like to be 90% confident that your estimate is within 2 of the true population mean. How large of a sample size is required? n || Do not round mid-calculation. However, you are encouraged to use a critical value accurate to three decimal places - this is important for the system to be able to give hints for incorrect answers.

A small rock sits on the edge of a tall building. A strong wind blows the rock off the edge. The distance, in feet, between the rock and the ground t seconds after the rock leaves the edge is given by d = -16t² - 8t+470. If the answer is not an integer, enter it as a decimal. Round to the nearest hundredth, if needed. How many seconds after the rock leaves the edge is it 443 feet from the ground? seconds How many seconds after the rock leaves the edge does it hit the ground? seconds
