Barbara used the distributive property to write an expression that is equivalent to 7 d + 63. Her work is shown below. The greatest common factor is 7 so 7 d + 63 = 7 (d + 63) What was Barbara's error? Barbara wrote (d + 63) instead of 63 d). Barbara wrote (d + 63) instead of (d + 9). Barbara wrote (d + 63) instead of (d + 56). Barbara wrote (d + 63) instead of (10 d).

What is the measure of angle x? a.101 b.158 c.44 d.79

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 > ?
