Sharon is paving a rectangular concrete driveway on the side of her house. the area of the driveway is 5x2 + 43x ? 18, and the length of the driveway is x + 9. additionally, sharon plans to install a carport over a small portion of the driveway. the volume that the carport can enclose is 48x3 + 68x2 ? 8x ? 3, and the area of driveway beneath the carport is 8x2 + 10x ? 3. determine the width of the entire driveway and height of the carport in terms of x. replace the values of m and b to complete the expression that represents the width of the entire driveway on the first line, and then replace the values of m and b to complete the expression that represents the height of the carport on the second 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 > ?
