Marina volunteers at the Salvation Army. She has been tasked with buying nonperishable items for families that were displaced by a recent flood. She finds a company willing to sell her cans of food at a discounted price of $2.25 for a small can and $4.75 for a large can. She spent a total of $714.75 and bought 181
cans. Let x represent the number of small cans she purchased and y represent the number of large cans she purchased.

Based on this context, are there any constraints on the variables that we should consider?

A) non-negative integers greater than 2.25 and less than 4.75

B) integers greater than 0

C) no constraints are needed on the variables.

D) non-negative integers greater than 0 and less than 181.

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 > ?
