Answer:

Yes, it is a function

Step-by-step explanation:

A function has only one output for each input. So a function can have the same output for different input, but one input can only have one output. In this case none of the inputs output more than one output, so it is a function.

A) work out the radius of the mercury, giving your answer as an ordinary number

guapka [62]

Answer:

a. 2,440 km

b. $1.33*10^{27} kg$

Step-by-step explanation:

a. Diameter of Mercury = $4.88*10^3$

Radius of Mercury = ½ of its diameter = $\frac{4.88*10^3}{2}$

Radius of Mercury = $2.44*10^3$

To convert the radius to ordinary number, multiply 2.44 by 1,000.

Radius of Mercury as an ordinary number = $2.44*1,000 = 2,440 km$

b. Mass of Jupiter = $1.898*10^{27} kg$

Mass of Saturn = $5.68*10^{26} kg$

Difference between mass of Jupiter and mass of Saturn = $1.898*10^{27} - 5.68*10^{26}$ (subtract 5.68 from 1.898 = 5.68. we would retain the largest exponent, which is raised to the lower of 27.)
