sin theta = -3/5, cos theta < 0 Solution cos theta = -4/5 csc theta = -5/3 sec theta = -5/4 tan theta = 3/4 cot theta = 4/3
What is 5 1/2 – 7 ? Adding and subtracting rationals Solution 5 1/2 – 7 = (11/2) – (14/2) = -3/2
Solution To find 8% of 45, first rewrite 8% as a decimal by moving the decimal point two places to the left to get .08. Next, the word “of” means multiply, so we have (.08)(45) which is 3.6. So 8%…
1) Define the intersection points. (Show how you get the points). 2) Shaded the region bounded. 3) Evaluate the area (show the calculations). Solution The intersection is found by equating the two curves f1(x) = f2(x) or x3+2×2=x+1 or x3+2×2-x-1…
Solution 195/365 x .1055 x 5450 = 307.178 = $307.18 195/335 = 0.53425, over half a year 0.53425 x .1055 = .056363 .056363 x 5450 = 307.18
