Polygon ABCD has sides with these lengths:AB, 5 units; BC , 4 units; CD,4.5 units, and AD 7 units, the slope of AB is 5, the slope of BC is 0.25, the slope of CD is -2, and the slope of AD is 0. The polygon is dilated from point A by a scale factor of 1.2 to form polygon A’B’C’D. Match the slopes and lengths of the sides of the polygon A’B’C’D to their values

If your teacher tells you to do questions 6 through 19 in your math book for homework, how many questions is that

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4 by substituting x = 1 and x = 2.

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 > ?
