The volume of a cylindrical canister is given by the formula V=nr^2h Part1. Write a function f(V) to express the radius of the canister as a function of the volume. Part 2. Suppose a certain type of canister must have a height of 32 centimeters (cm), so the quantity nh is about 100 cm. Write an updated version of the function f(V), using 100 for nh, to determine the radius of the canister that would result in certain volumes. Complete the table to find the values of f(V) for V = 25; 100; 625; 900; 2,500; and 10,000. Part 3. Plot the points from your table on the grid and sketch the graph. Part 4. If the graph were rotated 90° counterclockwise about the origin, which function would the result resemble? Explain your answers, including relating the two functions. This question left me stumped. I can't think of an answer, please show me how you do it so I can understand this better and not need help.​

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
