Soon after taking an aspirin, a patient has absorbed 320 mg of the drug. after 3 hours, only 40 mg remain. find an exponential m
Anastaziya [24]
The equation will be of the form:
A(t)= A_{0} e^{rt}
where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:
40=320e^{3r}
Rearranging and taking natural logs of both sides, we get:
ln\ 0.125=3r
r=\frac{ln\ 0.125}{3}=-0.693
The required model is:
A=A _{0} e^{-0.693t}

Step-by-step explanation:

1: if you see something to the power you will always think of repeated multiplication off the bat. so you just multiply the coefficient by the amount of the exponent.

2: 1*1*1*1*1*1*1*1*1*1*1*1*1*1*1*1=1 no

2*2*2*2=16 yes

4*4=16 yes

8*8=64 no

16=16 yes

3: 3/4*3/4*3/4=27/64

hope this helps! have a nice day!
