John has a rectangular piece of zinc with a perimeter with a perimeter of 32 cm. he wants to use that piece of zinc to build an open cylinder at both ends.
find the length and the width, in cm, of the piece of zinc that makes the volume of the cylinder is maximum.

Iwill mark brainliest worth 30 pointsthe distance, y, in centimeters, of an ant from a hole in the tree for a certain amount of time, x, in seconds, is shown in the graph: a graph titled motion of ant is shown. the graph shows time in seconds on the x-axis and the distance from hole in centimeters on the y-axis. the scale on the x-axis is shown from 0 to 6 at increments of 1, and the scale on the y-axis is shown from 0 to 12 at increments of 2. the graph has 3 straight lines. the first line is labeled p and joins ordered pairs 0, 0 and 2, 6. the second line is labeled q and joins ordered pairs 2, 6 and 3, 6. the third line is labeled r and joins ordered pairs 3, 6 and 5, 0.part a: is the graph linear or nonlinear? explain your answer. (2 points)part b: in which segments is the graph increasing, decreasing, and constant? (3 points)part c: in your own words, describe the motion of the ant, as shown on the graph. (5 points)
