Bill launched a model rocket, and estimated its height h, in feet, after t seconds. His results are shown in the table. Time, 1 0 1 2 3 4.
Height h 0 110 190 240 255
Bill's data can be modeled by the function h(t) = -1612 + 1281.
Which value is the best prediction for the height of the rocket after 5.5 seconds?
O A. 150 ft
OB. 180 ft
OC, 220 ft
D. 250 ft
E 260 ft

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
