Using intercepts and the maximum, find an equation for the graph shown. a)f(x) = 3x2 + 6x - 9 b) f(x) = 3x2 + 6x + 9 c) f(x) = -3x2 + 6x - 9 d) f(x) = -3x2 + 6x + 93x2 is 3 the the 2nd power

For each expression use a property to write an equivalent expression.

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).

21 type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. the solution set of n2 - 14n = -45 is { (separate the solutions with a comma)
