Drug Name Half-life
-----------------------------------
Acetaminophen 1-4 hours
Ibuprofen 1.8-2 hours
Loratadine 8.4 hours
Lithium 8 hours
Diphenhydramine 5.3-11.7 hours

The table above displays the half-lives of 5 common house hold drugs. The half-life (h) is the time is takes for a substance to reduce to half its initial value (A0). Half life can be used to solve for the amount (A) of a substance left after t time by using the following equation:

A=A^0⋅(12)^t/h
If Scott was administered 300 mg of Lithium, which of the following represents how much lithium, rounded to the nearest hundredth of a mg, could be left in Scott's blood stream after 12 hours?

Select one:
A. 157.23
B. 106.07
C. 212.17
D. 188.99

Answers

Answer:

B. 106.07

Step-by-step explanation:

To make use of the given formula for amount remaining, we need to know the original amount (300 mg), the elapsed time (12 h), and the half-life of the substance of interest (8 h).

Setup

Using the given formula with the relevant values, we have ...

A = (300 mg)·(1/2)^(12/8)

Evaluation

Using a calculator to evaluate this expression, we find the amount of Lithium remaining in Scott's system after 12 hours to be ...

A ≈ 106.07 mg

Write an explicit formula for a , the nth term of the sequence 7, 14, 28, ...

Answers

Answer:

The sequence 7, 14, 28, ... is a geometric sequence with first term 7 and common ratio 2. The explicit formula for a geometric sequence is a_n = a_1 r^(n-1), where a_n is the nth term, a_1 is the first term, and r is the common ratio. In this case, a_n = 7 (2)^(n-1).

Here are the first few terms of the sequence:

n = 1: a_1 = 7

n = 2: a_2 = 14

n = 3: a_3 = 28

n = 4: a_4 = 56

n = 5: a_5 = 112

As you can see, the formula works for all values of n.

What is the area of this polygon?
A) 24 cm2
B) 16 cm2
C) 40 cm2
D) 18 cm2

Answers

Answer:

C) 40 cm²

Step-by-step explanation:

area of top triangle = 1/2 x 8 x 6 = 24 cm²

area of bottom triangle = 1/2 x 8 x 4 = 16 cm²

24 cm² + 16 cm² = 40 cm²

C would be the answer this is the correct answer because it makes most sense and also that’s correct because

The area of the top is :1/2x8x6=24 cm
Next!!

The area of the bottom is:1/2x8x4=16cm
Next!!
24 cm +16 cm = 40cm
