Step-by-step explanation:

Scientific Notation is a shortened form of writing a number using exponents. It has the following rules:

Use a positive exponent for large numbers greater than 1. Use a negative exponent for small numbers less than 1. Always write the first number as a value between 0 and 9.

9.4 x 10^-4 has a negative exponent and will be a number smaller than 1. This means 0.00094 and 0.0094 are options. Now count from the decimal in each to the space between 9 and 4. In the first it is 4. In the second it is 3. Since the exponent is - 4, this means 0.00094 is the solution.
