A ROCKET IS LUNCHED WITH AN INITIAL UPWARD VELOCITY OF 320 FEET PER SECOND FROM AN INITIAL HEIGHT OF 15 FEET. THE FUNCTION h(t)=16t^2 +320t +15 MODLES THE HEIGHT OF THE ROCKET IN FEET t SECONDS AFTER IT WAS LUNCHED. For how many seconds is the height of the rocket greater than or equal to 1,039 feet?

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
