Using exponential functions, it is found that:

a) Since the <u>amount of caffeine will be less than 50 mg</u>, the patient will be ready for the blood test by 6 a.m.

b) The patient could have ingest 231 milligrams of caffeine.

A decaying <em>exponential function</em> is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.
r is the decay rate, as a decimal.

In this problem:

Caffeine metabolize at a rate of 13% per hour, hence $r = 0.13$ .

Then:

$A(t) = A(0)(1 - r)^t$

$A(t) = A(0)(1 - 0.13)^t$

$A(t) = A(0)(0.87)^t$

Item a:

The coffee cup contains 150 milligrams of caffeine, hence $A(0) = 150$ .

At 6 a.m., it is 8 hours after drinking the coffee, hence we have to find A(8).

$A(t) = A(0)(0.87)^t$

$A(8) = 150(0.87)^8$

$A(8) = 49.2$

Since the <u>amount of caffeine will be less than 50 mg</u>, the patient will be ready for the blood test by 6 a.m.

Item b:

This A(0), considering <u>A(11) = 50</u>, hence:

$50 = A(0)(0.87)^{11}$

$A(0) = \frac{50}{(0.87)^{11}}$

$A(0) = 231$

The patient could have ingest 231 milligrams of caffeine.

Answer:

Step-by-step explanation:

-7k = 0

Divide both sides by (-7)

k = 0

17) c - 4 = -23

Add 4 to both sides

c - 4 + 4 = -23 + 4

c = - 19

$18) \dfrac{r}{-2}=-16\\\\\\Multiply \ both \ sides \ by \ (-2)\\\\\dfrac{r}{-2}*(-2) = (-16)*(-2)\\\\\\r = 32$
