The growth of a sample of bacteria can be modeled by the function bt=1001.06t where b is the number of bacteria and t is time in
alukav5142 [94]

Given:

The growth of a sample of bacteria can be modeled by the function

b(t)=1001.06t

where, b is the number of bacteria and t is time in hours.

To find:

The number of total bacteria after 3 hours.

Solution:

We have,

b(t)=1001.06t

where, b is the number of bacteria and t is time in hours.

Substituting t=3, we get the number of total bacteria after 3 hours.

b(3)=1001.06(3)

b(3)=3003.18

Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.

b(3)\approx 3003

Therefore, the number of total bacteria after 3 hours is about 3003.

Joe drove 538 miles in 9 hours 15 minutes what was his average speed per hour
DanielleElmas [232]
To calculate any speed, the equation is speed=distance/time
Basically, you first need to take your 9 hours and 15 minutes and combine them into a number with a decimal value.
So, 15*4=60
Sound familiar? Good, because 25*4=100, so they are the same here.
So, we can say 9 hours and 15 minutes is equal to 9.25
Take this now: Speed=538/9.25
You get 58.1621, which you can round to 58.2
This is, of course, your final answer, so Joe drove at 58.16 mph
