he effectiveness of a certain medical injection is modeled by 0.03t(70−t), where t is time in minutes and E is a measure of concentration in the bloodstream. Effectiveness readings above 17 are satisfactory and readings above 56 are dangerous. Step 2 of 2 : How high do the effectiveness readings get?
