Hi there! 

Your question: 

Sales fall from 300 per week to 270 per week what's the percentage change?

My answer:

The formula for calculating percent change is as follows: 

[(y2 - y1)/y1]*100=your percent change 

y2= first value 
y1=second value 

Plug the numbers in: 

[(300-270)/300]*100

[30/300]*100

0.1*100

10 

Therefore, the percent change is 10%

Hope this helps! Let me know if it's incorrect so I can fix it:)

Let g(x) = root of 4x and f(x) = 3x^3 + 8x^2 , what is the expression of the compound h(x) = g(f(x)) ?​
Nitella [24]

The composite function as shown is g(f(x)) =\sqrt{12x^3+32x^2}

<h3>Composite functions</h3>

Given the following fnctions

f(x) = 3x^3 + 8x^2\\g(x) = \sqrt{4x}

The composite function g(f(x)) is expressed as:

g(f(x)) =g(3x^3 + 8x^2)\\g(f(x) )=\sqrt{4(3x^3 + 8x^2)} \\g(f(x)) =\sqrt{12x^3+32x^2}

Hence the composite function as shown is g(f(x)) =\sqrt{12x^3+32x^2}
