During a manufacturing process, a metal part in a machine is exposed to varying temperature conditions. The manufacturer of the machine recommends that the temperature of the machine part remain below 141 degrees Fahrenheit. The temperature T in degrees Fahrenheit x minutes after the machine is put into operation is modeled by T=-0.005x^2 + 0.45x + 125. Will the temperature of the part ever reach or exceed 141 degrees Fahrenheit? Use the discriminant of a quadratic equation to decide. a. yes
b. no
