To begin a bacteria study, a petri dish had 2700 bacteria cells. Each hour since, the number of cells has increased by 5.2%. Let t be the number of hours since the start of the study. Let y be the number of bacteria cells.

Write an exponential function showing the relationship between y and t.

(! ) three cylinders have a height of 8 cm. cylinder 1 has a radius of 1 cm. cylinder 2 has a radius of 2 cm. cylinder 3 has a radius of 3 cm. find the volume of each cylinder

The sum of the reciprocal of a positive number and the reciprocal of 2 more than the number is 3/4 equation: the number is

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
