The speed of light in a vacuum is about 3000000000 meters per second, which can be written as 3 x 10n meters per second. What is n

n = 9.

Step-by-step explanation:

There are 9 0's after the 3 so it's

3 x 10^9.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
