Quick zap sold 5550 apps in the first week of availability. suppose that on average they expect to sell 45 apps per hour. a) write an equation for the number of apps a sold t weeks after the first week of availability. b) if sales continue at this rate, how many hours will it take for the company to sell 100,000 apps?

Which value of m will create a system of parallel lines with no solution? y= mx - 6 8x - 4y = 12

What is the solution to the division problem below x3+x2-11x+4/x+4

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 > ?
