Answer: This question has no answer. The closest i could get was b= -95/3 + 2/3 a
Step-by-step explanation:
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.
Answer:
the scale factor is the vertical expansion factor.
Step-by-step explanation:
The scale factor of 2 in
g(x) = 2·F(x)
means g(x) is a <em>vertical expansion</em> (not shrink) of F(x) — by a factor of 2.
_____
<em>Additional comment</em>
The equation g(x) could be considered to be ...
g(x) = F(x·√2)
in which case g(x) could be interpreted as a <em>horizontal shrink</em> by a factor of (√2)/2. Squeezing a parabola horizontally has the same effect on its appearance as stretching it vertically.
That's written as 5.6 x 10⁻¹⁷ .
(To change 5.6 into the original number, you'd need to
move the decimal point 17 places backwards.)
Answer:
the woman has to live 1 mile from work to minimize the expenses
Step-by-step explanation:
Given the data in the question;
the distance within 9 miles ⇒ 0 < x > 9
Total costs Q = cx + 4c/( x + 1)
costs should be minimum ⇒ dQ/dx = 0
⇒ d/dx [ cx + 4c/( x + 1) ] = 0
⇒ ( x + 1)² = 4
take square root of both side
√[ ( x + 1)² ] = √4
x + 1 = 2
x = 2 - 1
x = 1
Therefore, the woman has to live 1 mile from work to minimize the expenses
