Suppose there exists a planet with 3.1 billion inhabitants. the surface area of this planet is 490,784,119 km ^2. what is the surface area of the planet in mi^2? round to the nearest million square miles.

190 milion square miles

Step-by-step explanation:

The conversion factor between kilometer and mile is:

1 mile = 1.609 km

So, the conversion factor between the squared mile and the square kilometer is

So we can set up the following proportion to find the surface area in mi^2:

Rounded to the nearest milion square miles, it is 190 milion square miles.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

answer: 40.95
