Find the area of a rectangular garden box if the length is square root of 6ft. and the width is square root of 21 ft. write the answer in simplest radical form.

2. there is a threshold on a person's weight that tells doctors when a person is at a greater risk of death. in men, ages 40 - 49, that threshold weight is represented by h=12.3 squared 3 square root of t, where h is height in inches and t is the threshold weight. if a doctor told a 43 year old man that his threshold weight was 218 lbs what would that man's height be (in the form of feet -inches: ex: 5 ft 9 in)?

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 > ?
