For this discussion I’m using Cowling’s Rule to find out a 5 year old child’s dosage of adult’s dosage (75mg) Tamiflu. After reading Elementary and Intermediate Algebra I have learned Cowling’s Rule is a formula which converts adult’s dosage into children’s dosage, using the age of the child. The literal equation will have three variables. The formula used is d = D (a + 1). The following is the variables for the literal equation: a = child’s age – 5 Years old

D = adult dose – 75 mg
d = child’s dose
I have been assigned to calculate a 5-year-old child’s dose of tamiflu given that the adult dose is 75mg. d = D (a + 1) The Cowling’s Rule formula
24

d = 75 (5 + 1) Substituted 75 for D and 5 for a.
24

d = 18.75Division is the last step in solving for the child’s dose. The proper dose of tamiflu for a 5 year old child is 19mg.

For part B of the discussion I will determine a child’s age based on the dose of medicine he/she was prescribed. The same equation can be used, but I will be solving for another variables instead of d. The dose is 1200mg for an adult and 300mg for child. I will be solving the equation for a. The following is the variables for the equation: a = child’s age

D = adult dose – 1200 mg
d = child’s dose – 300 mg
d = D (a + 1) The Cowling’s Rule formula
24

300= 1200(a + 1) Substituted 1200 for D and 300 for d.
24

300(24) = 1200(a + 1)(24) Multiplied by 24 to eliminate denominator. 24

7200 = 1200(a + 1) Multiplication on left side is
24carried out.

7200= 1200 (a + 1) Divide both sides by 1200
1200 1200

6= a+1One last stepped before the equation is solved.

6 – 1 = a + 1 – 1Subtract 1 from both sides to isolate a.

5= ANow I have solved.
The dose of 300mg is intended for a five-year-old child. There are only one potential answer for this...

The Body Mass Index (BMI) is an indicator to help people to determine if they might have a longer life span than average, are probably not overweight, are probably overweight, or are obese. The intervals for each are from 17 to 22, 23 to 24.999, 25 to 29.9, and over 30 respectively. Notice that it is between 17 and 22. That is not inclusive...

Buried Treasure
In this essay of Buried Treasure we will use many different ways to attempt to factor down three expressions problems. Our first problem from our reading talks about Ahmed and Vanessa, Ahmed has half of a treasure map, which indicates that the treasure is buried in the desert 2x + 6 paces from Castle Rock. The other half of the map is in Vanessa possession and her...

...The Mats by Francisco Arellana
For my family, Papa’s homecoming from his many inspection trips around the Philippines was always an occasion to remember. But there was one homecoming - from a trip to the south – that turned out to be more memorable than any of the others.
Papa was an engineer. He inspected new telegraph lines for the government. He had written from Lopez, Tayabas:
I have just met a marvelous matweaver – a real artist – and I shall have a surprise for you. I...

...The Mats
The story assigned to our group is ‘The Mats”. And based on our discussions and group meetings, the interpretation we all agreed to make is the “reader-based interpretation”.
The Mats, written by Francisco Arcellana, is a short story depicting a very typical Filipino value – a deep sense of close family-ties and bonding. In this particular story, a man -depicted as a very loving and thoughtful father/husband- seems to still not able to...

...Buried treasure. Ahmed has half of a treasure map, which indicates that the treasure is buried in the desert 2x - 6 paces from Castle Rock. Vanessa has the other half of the map. Her half indicates that to find the treasure, one must get to Castle Rock, walk x paces to the north, and then walk 2x - 4 paces to the east. If they share their information then they can find x and save a
lot of digging. What is x?
Given this scenario the Pythagorean Theorem would be the strategy we use to solve...

On to T3! As I said for the previous essay you may well have had this bundled in with T2 and be doing them both the same week. It pulls out from that question on legislation and codes of practice to focus closer on these particular and important issues. Check out the full list of Ptlls assignments if you need a different one.
