Answer:
a) The slope of the graph of c is 8.34.
b) The dosage for a newborn is 8.34mg.
Step-by-step explanation:
A first order function in the following format

Has slope b.
The appropriate dosage c is a function of the age a.
In this problem, we have that:

Suppose the dosage for an adult is 200 mg. This means that 
So


(a) Find the slope of the graph of c.
The slope of the graph of c is 8.34.
(b) What is the dosage for a newborn? (Round your answer to two decimal places.)
A newborn has age a = 0. So this is c(0).


The dosage for a newborn is 8.34mg.
Step-by-step explanation:
If you know, the sine. You must find the cos ratio, using the Pythagorean trig theorem.
Next, you use the half angle identity for sin

Example.

We must find

First, use the Pythagorean identity





Now use the half angle identiy




So the answer for our example is 1/2
The factors are 3 and (4r+y)
