The Sun is 2.093 × 108 km (kilometers) from Mars and the speed of light is 2.5 × 108 m/s. Calculate the time it takes light, from the Sun, to reach Mars. (Remember: distance = speed x time (d = st)

Step-by-step explanation:

d = 2.093 * 10^8 km

r = 2.5 * 10^8 meters = 2.5 * 10^8 meters * 1 km / 1000 m

r = 2.5 * 10^5 km/s

t = d/r

t = 2.093 * 10^8 km / 2.5 * 10^5 km/sec

t = 837.2 seconds

t = 13.95 minutes

I think there's an error in the question, The second answer would be right if the power were a +2

I would ask your teacher about this one.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
