Answer:
1:3.2km
Step-by-step explanation:
-Given the scale 1:320000 all in centimeters.
-We need to convert the represented cm dimension into kilometers.
#We know that 1cm equals 0.00001 km.
We therefore multiplied the represented dimension by 0.00001 km:
![=320000\times 0.00001 km\\\\=3.2 \ km](https://tex.z-dn.net/?f=%3D320000%5Ctimes%200.00001%20km%5C%5C%5C%5C%3D3.2%20%5C%20km)
Hence the scale i s 1cm represents 3.2km thus 1:3.2km

Answer:
The graph of g(x) is the graph of f(x) moved down 4 units.
Step-by-step explanation:
Subtracting a function by a constant:
Subtracting a function by a constant x is the same as moving the function down x units.
In this question:
![f(x) = 2^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%202%5Ex)
![g(x) = 2^x - 4](https://tex.z-dn.net/?f=g%28x%29%20%3D%202%5Ex%20-%204)
Thus, the graph of g(x) is the graph of f(x) moved down 4 units.
