a dog once a day for a rate of $5 per day. plan 2 also includes one walk a day but charges 1 cent for 1 day, 2 cents
for 2 days, 4 cents for 3 days, and 8 cents for 4 days and continues to double for each additional day. mrs. maroney
needs jayden to walk her dog every day for two weeks. which plan should she choose? show the work to justify
your answer

The expression 6x2 gives the surface area of a cube, and the expression x3 gives the volume of a cube, where x is the length of one side of the cube. find the surface area and the volume of a cube with a side length of 6m

When 142 is added to a number the result is 64 more times the number my options are 35 37 39 41

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.
