The weekly sales in thousands of items of a product has a seasonal sales record approximated by n= 84.59 + 24.8 sin (t is time in weeks with t = 1 referring to the first week in the year). during which week(s) will the sales equal 96,990 items? a. week 21 and week 30b. week 4 and week 47c. week 4, week 20, and week 52d. week 30 and week 47

Describe a situation that you could represent with the inequality x< 17

Which strategy is used by public health to reduce the incidence of food poisoning?

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 > ?
