Prob 1) An owner raises a $60 coat by 40% then reduces it by 40%.. When raised by 40% you multiply by 1 plus that.. so 60(1.4) = 84 Now when you reduce anything by a discount, you mult by that discount to get the discount amount.. 84(.4) = $33.60 discount.. so new price is 84-33.6 = $50.40 OR... another way .. preferred way... simply multiply the original price by (1-discount rate) to give you the new price so.. 84(1-.4) = 84(.6) = $50.40 just the same Once it is raised to 84, what discount must we apply to get it back to 60? I set it up like so.. 84(x) = 60.. but once we find x we need to subtract 1 from x to get the discount.. because same as above..original * (1-the discount rate) gives us the new price.. so to find the actual discount rate in this instance, we need to find x then subtract it from 1 to get the actual discount rate 60/84 = .714 or 71.4%.. so the discount rate is 1-.714 = .286 or 28.6%

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 > ?
