Answer:
Distance from Earth to Proxima Centauri (in scientific notation) =
kilometers
Step-by-step explanation:
We need the conversion between Astronomical Unit and Kilometers.
The conversion is:
1 AU = 1.496*10^8 km
or rounded, given in this problem,
1 AU =
km
We need the distance from Earth to Proxima Centauri:
AU *
kilometers
When multiplying two numbers in scientific notation, we have to "multiply the coefficients" and "add the exponents".
Lets do this:

Distance from Earth to Proxima Centauri (in scientific notation) =
kilometers
where's the graph??
I can't answer this without the graph
