1) A mail truck can transport no more than 3200 pounds (lbs.) with a volume of no more than 500 cubic feet (fe). The truck transports two sizes of packages. The small package has a weight of 20 lbs. and a volume of 4 ft. The large
package weighs 60 lbs, and has a volume of 10 fe? Let x be the number of small packages and y be the number of large
packages. Write a system of equations to represent the situation. (Make sure to simplity each equation by dividing out
any common factors.)

Witch represents the inverse of the function f(x)=1/4x-12

Find the interior angle of a regular polygon which has 6 sides

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 > ?
