Asupermarket employee is making a mixture of cashews and almonds. cashews cost $7 per pound, and almonds cost $5 per pound. the employee wants to make less than 6 pounds of the mixture and wants the total cost of the nuts used in the mixture to be not more than $30. let x represent the number of pounds of cashews. let y represent the number of pounds of almonds. select all inequalities that represent constraints for this situation.
a. x + y ≤ 6

b. 7x + 5y < 6

c. x + y < 6

d. 7x + 5y > 30

e. 7x + 5y ≤ 30

f. x + y ≤ 30

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 > ?
