Elena and jorge have similar problems and find the same answer. each determines that the solution to the problem is 24.
elena: (14 + 42) ÷ 7 + 4²
jorge: 14 + (42 ÷ 7) + 4²
a. evaluate each expression to determine if both elena and jorge are correct.
b. why would each find the solution of 24? what mistakes were made, if any?

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 > ?
