1. the radioisotope iodine-123 is used in thyroid therapy. the half-life of this isotope is 13.27 hours. which equation determines the percent of an initial amount of the isotope remaining after t hours? a = 13.27 (1/2)^100/t a = 100 (1/2)^13.27/t a = 13.27 (1/2)^t/100 a = 100 (1/2)^t/13.27 2. a ladder leans against a building. the foot of the ladder is 2 feet from the building and reaches to a point 7 feet high on the building. what is the measure of the angle formed by the ladder and the building? enter your answer, rounded to the nearest degree, in the box.
