The exponential equation would be 8000 (1.125)^t where t represents the number of hours. If you want to find the doubling time of the bacteria, you would put the equation like this: 8000 (1.125)^t = 16000. 
1) 1.125^t = 2
2) log_1.125(2) = t
3) t = 5.8849491924
Rounding the time to the nearest 0.01 hours would give you 5.88 hours.

ser-zykov [4K]

Answer:

No   g(x) = x/6     for (60, 10) to be a possible solution

by this function 60 people would have to donate 1/6th of a garment each to achieve 10 full garments

Step-by-step explanation:

g(x)   number of items

   x   number of people  

the data point (60, 10) make sense as a possilbe solution     NO

g(x) = number of items       x = 60   g(x) = 10

g(60) = x/6 = 10              

         = 60/10            

by this function 60 people would have to donate 1/6th of a garment each to achieve 10 full garments

AlladinOne [14]
You multiply the 4.00 by 0.10 to get the 10% discount amount. Then you subtract that from $4.00. Then you multiply that amount by 1.06 to get the total with the 6% sales tax. To get $3.82 rounded to the nearest cent.
