Fiona is serving iced tea and lemonade at a picnic. she has only 44 cups in which to serve the drinks. if x represents the number of glasses of iced tea and y represents the number of glasses of lemonade, which equation represents the number of drinks she can serve? 1. x – y = 442. 44 + y = x3. y – x = 444. x = 44 – y

Which of the following would be a good name for the function that takes the weight of a box and returns the energy needed to lift it?

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 > ?
