Select the correct answer. Haley conducted a study which found that a cup of coffee contains 150 milligrams of caffeine. The amount of caffeine in the body each
hour after consumption of one cup is 9% less than the previous hour.
If Haley conducted her study for a total of 10 hours, which inequality represents the range of the exponential function that models this
situation?
150 s f(x) s 355.1
58.41 s f(x) < 150
O s f(x) s 10
0 <f(x) s 150

The correct option is (B).

Step-by-step explanation:

The exponential decay function is as follows:

Here,

y = final value

a = initial value

r = decay rate

t = time taken

It is provided that:

a = 150 mg

r = 9% = 0.09

Then the next hour the amount of caffeine in the body will be:

Then after two hours the amount of caffeine in the body will be:

Similarly after 10 hours the amount of caffeine in the body will be:

Then the inequality representing the range of the exponential function that models this  situation is:

Thus, the correct option is (B).

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
