Since this culture of bacteria obeys the law of uninhibited growth. Given that 500 bacteria are present initially, and there are 800 after 1 hour, a growth rate of 0.470003629246 (k value) has been calculated. <span>5243 </span>will be present after 5 hours.

The law of uninhibited growth follows below formula:

A = Pe^(rt)

For your problem, we need to first look for the rate, given the initial and final number of bacteria..

A = Pe^(rt)
800 = (500)(e)^r(1)

(800/500) = (e)^r(1)
ln (8/5) = ln (e) ^ r
r = 0.47

substitute the value of r to get the number of bacteria after 5 hours:

A = Pe^(rt)
A = (500)(e)^(0.47)(5)

A = 5,242.78 or 5,243

Alex runs on the track at school each weekday morning. If he runs 5.9 miles each day, about how much does he run every month?
Lisa [10]
Now, since we know that 5.9 is the amount of miles per day, we need to determine how many miles per month.

Usually, there are 20 days...because of no weekdays

Multiply.

5.9 * 20 = 118

Final answer:- He runs 118 miles per month.

Use cavalieri's Principle to calculate the exact of an oblique cylinder with a radius of 10 meters and a height of 11 meters.
Readme [11.4K]
Am I to assume this is for volume? The volume formula for a cylinder...oblique or not...is V = 1/3pi r^2 h.  Cavalieri's principle tells us that the formulas for both are the same. So V = 1/3*pi*100*11 and V = 366.67 pi
