Rocky has 7 bottles of water. he will buy more bottles of water from the store. the store has 8 cases in stock and each case contains 24 bottles of water. the store will not sell partial cases. the function that models the number of bottles of water rocky will have after his purchase is f(c)=24c+7, where c is the number of cases of water he buys. what is the practical domain of the function? what is the practical domain of the function? (a) {31, 55, 79, 103, 127, 151, 175, 19 9} (b) all integers from 1 to 8, inclusive (c) all real numbers from 1 to 8, inclusive (d) all real numbers

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

Find the area of the region that is inside r=3cos(theta) and outside r=2-cos(theta). sketch the curves.

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 > ?
