Explain what is unusual about ie solution set of the inequality. x24x+1550 O The solution set consists of the real numbers x = i, x = D, and x = 15. O The solution set is all real numbers. 0 The solution set is all real numbers exoeptx = 4, or {m, 4) U (4, on). O The solution set is empty. 0 The solution set consists of a single real number %. Use the position equation 5 = 15t2 + vat +50 where 5 represents the height of an object (in feet), Va represents the initial velocityr of the object (in feet per second], 53 represents the initial height of the object (in feet], and t represents the time (in seconds). A projectile is red stlaight upward from ground level (so = D) with an initial velocity of 96 feet per second. (a) At what instant will it be back at ground level? sec (b) when will he height exceed 123 feet? [Enter your answer using interval notation.)
