Performance Task: Modeling with Sinusoidal Functions on edge. If you have this finished and can help me out, it would be GREATLY appreciated.

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b.you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c.you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d.you spend $5 plus $10 per week until you have less than $45.

Write an inequality for this description. - one fourth of the opposite of the difference of five and a number is less than twenty.

How can you find the magnitude of a vector, v = < x,y > , where the horizontal change is x and the vertical change is y?
