A bacterium in a petri dish multiplies by a factor of 5 every day. On day ,
there is 1 bacterium; on day 1, there are 5 bacteria, on day 2, there are
5.5= 25 bacteria; on day 3, there are 5.5.5=125 bacteria, and so on. What
logarithmic equation can be used to find the number of days it takes for a
colony of 1,000,000,000 bacteria to develop?

Which value of c would make he following expression completely factored? 8x+cy

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
