Suppose you have 56 feet of fencing to enclose a rectangular dog pen. The
function A = 28x - x2, where x = width, gives you the area of the dog pen in
square feet. Which of the following is the width that gives you the maximum
area and the maximum area?

The average length of a king cobra is 3.7 m. the record length is 1.88 m longer than the average. how long is the record holder?

Graph the line y=4/3 x+1 . use the line tool and select two points on the line.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
