Aperson's systolic blood pressure, which is measured in millimeters of mercury (mm hg), depends on a person's age, in years. the equation:
p=0.005y^2−0.01y+121
gives a person's blood pressure, p, at age y years.
a.) find the systolic pressure, to the nearest tenth of a millimeter, for a person of age 48 years.
b.) if a person's systolic pressure is 133 mm hg, what is their age (rounded to the nearest whole year)?
