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.

2х + Зу = 9
umka2103 [35]

Answer:

3

Step-by-step explanation:

Given the 2 equations

2x + 3y = 9 → (1)

- 2x + 2y = 6 → (2)

Adding the 2 equations term by term will eliminate x

(2x - 2x) + (3y + 2y) = (9 + 6), that is

5y = 15 ( divide both sides by 5 )

y = 3

qaws [65]
3b+2b+b=181.5
6b=181.5
6b/6=181.5/6
b=30.25

The baby panda eats 30.5 pounds and since the female panda eats two times that you multiply it by two.

30.25 x 2 = 60.5
