Brainliest to anybody that can answer all steps even if wrong but please at least try.

What basic trigonometric identity would you use to verify that csc x sec x cot x = csc^(2)x

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

Find the root(s) of f (x) = (x- 6)2(x + 2)2.
