What is the relative error and the percentage error? 5- (12points) Aladder L2feet longrestsalongaverticalwall. Ifthebottomoftheladderslides away from the wall at 3 fl/sec, how fast is the angle between the top of the ladder and the wall changing when the angle is f radians? 6. (15 points) Given the frrnctiony : 4 x*l a) find all asymptotes, b) find the local maximum and minimum points (if any), and c) sketch a graph of the function labeling,the asymptotes and the points fotrnd in b). 7. (12 points) A rectangular-box with an open top is to be made from apiece of cardboard with an area of 864rn2 (the total surface area of the open top box). fhe length of the base ofthe box is twice its width. Find the dimensions of the box (length, width and height) that will maximize the volume of the box. Show that your result is a maximum....
