(1 point) (a) the cartesian coordinates of a point are (1,1). (i) find polar coordinates (r,θ) of the point, where r> 0 and 0≤θ< 2π. r= θ= (ii) find polar coordinates (r,θ) of the point, where r< 0 and 0≤θ< 2π. r= θ= (b) the cartesian coordinates of a point are (23–√,−2). (i) find polar coordinates (r,θ) of the point, where r> 0 and 0≤θ< 2π. r= θ= (ii) find polar coordinates (r,θ) of the point, where r< 0 and 0≤θ< 2π.

Afriend of mine is giving a dinner party. his current wine supply includes 10 bottles of zinfandel, 8 of merlot, and 11 of cabernet (he only drinks red wine), all from different wineries. (a) if he wants to serve 3 bottles of zinfandel and serving order is important, how many ways are there to do this? ways (b) if 6 bottles of wine are to be randomly selected from the 29 for serving, how many ways are there to do this? ways (c) if 6 bottles are randomly selected, how many ways are there to obtain two bottles of each variety? ways (d) if 6 bottles are randomly selected, what is the probability that this results in two bottles of each variety being chosen? (round your answer to three decimal places.) (e) if 6 bottles are randomly selected, what is the probability that all of them are the same variety? (round your answer to three decimal places.)
