In euclidean geometry, the sum of the measures of the interior angles of a pentagon is 540°. predict how the sum of the measures of the interior angles of a pentagon would be different in spherical geometry. a. the sum would be greater than 540. b. the sum would still be 540°. c. the sum would be less than 540°. d. the sum would less than or greater than, but never equal to, 540°.

When y’all answer can y’all explain too !

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
