Sarah and her friends are going blueberry picking. sarah picks $b$ blueberries. michael picks $3$ more than half as many as sarah, and david picks $5$ more than michael. in addition, kaycee picks $10$ less than $3$ times as many as david and hannah picks twice as many as kaycee. find an expression in terms of $b$ for the number of blueberries that hannah picked.

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
