We are asked in the problem to find csc (13pi/6). first we can convert the radians angle first to degrees that is equal to 390 degrees. The terminal angle is 30 degrees. csc is the reverse of sin. sin 30 is equal to 1/2, positive since in the first quadrant. hence the answer is 2.
Answer:
You first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.
