Answer:
it is either 49 or 48
Step-by-step explanation:
Answer:
We lend 100% - 9.2% and this will equal 90.8%, then we will make this percentage of 42,600 which will give us 38,680 and we will add the 42,600 and this will give us a total of 81,460 copies.

Answer:
- f(x+h) = (2x² -x +2) +4xh -h +2h²
- (f(x+h) -f(x))/h = 4x -1 +2h
Step-by-step explanation:
Like a lot of algebraic manipulation associated with average rate of change, it is not difficult, but it can be tedious.
<h3>a)</h3>
![f(x+h)=2(x+h)^2-(x+h) +2 = 2(x^2 +2xh +h^2)-x -h +2\\\\\boxed{f(x+h)=2x^2-x+2+4xh-h+2h^2}](https://tex.z-dn.net/?f=f%28x%2Bh%29%3D2%28x%2Bh%29%5E2-%28x%2Bh%29%20%2B2%20%3D%202%28x%5E2%20%2B2xh%20%2Bh%5E2%29-x%20-h%20%2B2%5C%5C%5C%5C%5Cboxed%7Bf%28x%2Bh%29%3D2x%5E2-x%2B2%2B4xh-h%2B2h%5E2%7D)

<h3>b)</h3>
Then the difference quotient is ...
![\dfrac{f(x+h)-f(x)}{h}=\dfrac{(2x^2-x+2)+4xh-h+2h^2-(2x^2-x+2)}{h}\\\\=\dfrac{4xh-h+2h^2}{h}\\\\\boxed{\dfrac{f(x+h)-f(x)}{h}=4x-1+2h}](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%28x%2Bh%29-f%28x%29%7D%7Bh%7D%3D%5Cdfrac%7B%282x%5E2-x%2B2%29%2B4xh-h%2B2h%5E2-%282x%5E2-x%2B2%29%7D%7Bh%7D%5C%5C%5C%5C%3D%5Cdfrac%7B4xh-h%2B2h%5E2%7D%7Bh%7D%5C%5C%5C%5C%5Cboxed%7B%5Cdfrac%7Bf%28x%2Bh%29-f%28x%29%7D%7Bh%7D%3D4x-1%2B2h%7D)
Answer:
2/3
Step-by-step explanation:
Distance MS = √[(6-(-3))²+(3-3)²]= 9
Distance M'S' = √[(4-(-2))²+(2-2)²] =6
scale factor = |M'S'| /|MS|= 6/9 = 2/3
