The answer is B) The initial number of bacteria is 57, and the growth rate is 31% per hour.
The expression shown is an <em>exponential expression</em>. An exponential expression usually takes the form 
, as this one does. A represents the <em>initial value</em>, in this case-the initial number of bacteria. B represents the <em>growth rate</em>. When it is an increasing growth rate, it will begin with 1, because it will have everything it had before, plus the percent increase, the decimal portion. In this case, a=57, and b=0.31.
Hope this makes sense!
Answer:
you can do (500)(4) x 2
Step-by-step explanation:
500 x 4 = 2000
2000(2) = 4000

Answer:
248 miles
Step-by-step explanation:
we know that
After 3.5 hours ,Pasha had traveled 217 miles
so
using proportion
Find out how many miles she will have traveled after 4 hours
(100^5) * 4000 = 10000000000 * 4000 = <span>4 * 10^13</span>
