MaKayla sells square frames of various sizes. To find the area of a frame, she uses the formula A=\:s^2-\left(s-2w\right)^2A = s 2 − ( s − 2 w ) 2,

where s is the length of the frame and w is the width of the frame.

1. What does each term in the formula represent?

2. Find the area of a frame that measures 15 inches on each side and

has a width of 2 inches.

3. MaKayla charges 20 cents per square inch for her frames. How

much will she charge for a frame that measures 18 inches on each

side and has a width of 3 inches?

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 > ?
