The point (0, 5) lies on circle a with the center at the origin. does the point (0, −5 ) lie on the circle? a. yes, because both points are equidistant from the center of the circle. b. yes, because the distance between the two points is half the distance from the center to one of the points. c. no, because both points are not equidistant from the center of the circle. d. no, because the distance between the two points is twice the distance from the center to one of the points.

Darian wants to build a regulation size pool table that is 9 feet in length.he plans he ordered are 18 by 36 inches. what is the scale factor of the dilation he must use to build a regulation pool table

Yo need asap pls ! markin da brainiest too !

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 > ?
