O.118 seconds will be taken for a radio signal to travel from a satellite to the surface of earth.

Step-by-step explanation:

We are given Speed = 3.00 · 10^8 meters per second.

And Distance = 3.54.10^7 metwers

We need to find time.

We know that,

Distance = Speed * Time

3.54.10^7 = 3.00 · 10^8 * Time

Time = 3.54.10^7 / 3.00 · 10^8

Time = 1.18 X 10^7-8

Time = 1.18 x 10^-1

Time = 0.118 seconds.

So, O.118 seconds will be taken for a radio signal to travel from a satellite to the surface of earth.

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

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
