HELP!!! Please help me on this questions below and also draw graph too please and it's just one assignment which has this questions in it below those are little questions, please answer all of them correctly, I don't have any questions left, l'm posting this by buying additional question please answer them correctly I really need to submit it by today, I don't need explanation you can just submit all questions answers below please you can Zoom in and able to see questions below clearly I do really appreciate your hardwork and time please help me to answer them correctly:)
RF2_9B_Preview Score: 0/12 0/5 answered Question 1 In Reasoning with Functions 1, you learned how to factor expressions and add fractions with unlike Question 2 denominators. You will need to review these skills for the upcoming activities. The Pythagorean identity states that for any angle . sin?(0) + cos?(0) = 1 . Two other useful versions Part A: Factor '5 x^3-5 x^2- 10 x, if possible. 1 - sin? (0) - cos? (0) and 1 - cos?(8) - sin?(8). Answer: These identities may be used to simplify expressions. O Prime Example: Simplify 5 - 5 sin?(0) . Solution: 5 - 5sib?(0) = 5(1 - sin (0)) - 5 cos?(0). Simplify these expressions, using versions of the Pythagorean identity. Part B: Factor '9 x12 + 36 Part A: 7 - 7 cos? (0) Hint Answer: Prime Answer Part B: 12 - 12sin (6) . Assume that cos(0) # 0. 2 cos(8) Part C: Add '1/x + 1/(x+2) . Answer: Answer: Part C: \\64 - 64 cos?(0). You may assume that 0 5 0 S T.
