Find f(x) and g(x) so that the function can be described as y = f(g(x)).
mote1985 [20]
let g(x) = x^2+2 let f(x) = 9/x f(g(x)) is therefore equal to f(x^2 + 2) which is equal to 9/(x^2+2).

When 10 b = 5 (StartRoot c EndRoot + 2) is solved for c, one equation is c = (2b minus 2) squared Which of the following is an e
Burka [1]

Answer:

I will show all the steps to lead to the solution.

1) 10b = 5 (√c + 2)  <---- starting equation

2) divide by 5 => 2 b = √c + 2

3) subtract 2 => 2b - 2 = √c

4) raise to the power 2 => (2b - 2)^2 = c, which is the expression given.

Now these are two equivalent forms:

1) extract 2 from the parentheses: c = 4 (b -1)^2

2) expand the parentheses: c = 4b^2 - 8b + 4)

Answer:

The values is  

Step-by-step explanation:

From the question we are told that

  The population mean is  \mu  =  2.45

    The  standard deviation is  \sigma  = 0.35 \ mi

     The random value is  x =   2.03

The standardized score for a binding site position of 2.03 microns is mathematically represented as

       z-score  =  \frac{x -  \mu}{ \sigma }

=>      z-score  =  \frac{2.03 -  2.45}{ 0.35}

=>    z-score  =  -1.2
