Hello! I have a question on here. I am right now reviewing my Algebra 1 Material, so Ill be ready for Geometry. Could you also tell me why the answer is correct if possible? The function below can be used to model the area of a rectangle in square inches, A, if the rectangle has a perimeter of 72 inches and a width of w inches. ^ means the number after it is the power of

A=36w-w^2

In this situation, which of the following best describes the domain of the function?

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 > ?
