The stress distribution on a structure is given by s=2x^2+4x−30 where s is stress in pounds per square inch and x is the distance in feet from a reference point. At what distance is the stress equal to 0? f)6 ft g)3 ft h)12 ft j)5 ft

Gh bisects fgi. find the measure of hgi •15° •21° •10° •8°

Given: transversal t passed through parrallel lines r and s.prove: < 3 = < 6 < 4 = < 8what is the next step in the proof? choose the most logicsl approach

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
