Exponential Models The recommended dosage of ibuprofen for an adult is 400mg. Each hour, the amount of ibuprofen in the person's system decreases by about 29.5%. Which exponential function models the amount of ibuprofen left in your system after t hours? ​

i believe that the answer is

b. y-1=-2(x-4)

hope this !

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
