(this exercise shows that if you know one nontrivial solution of y 00 + p(x)y 0 + q(x)y = 0, you can use abel’s formula to find another.) suppose p and q are continuous and y1 is a solution of y 00 + p(x)y 0 + q(x)y = 0 (a) that has no zeros on (a, b). let p(x) = r p(x) dx be any antiderivative of p on (a, b). (a) show that if k is an arbitrary nonzero constant and y2 satisfies

The average hourly earnings for a construction worker is projected to be $24.50 in 2012. jason wants to join the construction work force after he graduates in 2012. his friend tells him that average hourly earnings for construction workers will rise by 2% from 2009 to 2012. based on the data below, assuming that the projected hourly earnings are correct, is jason’s friend’s statement accurate? construction industry - average hourly earnings, 2000-2009 a. his friend’s statement is accurate. the average hourly earnings will increase by 2%. b. his friend’s statement is not accurate. the percent increase will be more than 2% c. his friend’s statement is not accurate. the percent increase will be less than 2% d. his friend’s statement is not accurate. the average hourly earnings will decrease
