A biologist isolates two strains of a particular virus and monitors the growth of each, starting with samples of 0.02 grams. Strain A increases by 10% in 8 hours, and strain B increases by 13% in 11 hours. (a) How much did the sample of strain A weigh after 8 hours?
(Round the answer to four decimal places. Your answer must include units to receive full credit.)

(b) What was the hourly growth factor for strain A?
(Round the answer to four decimal places.)

(c) How much did the sample of strain B weigh after 11 hours?
(Round the answer to four decimal places. Your answer must include units to receive full credit.)

(d) What was the hourly growth factor for strain B?
(Round the answer to four decimal places.)

(e) Which strain of virus grows more rapidly? A or B

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.
