The volume of earth is on the order of 1021 m3 . (a) what is this in cubic kilometers (km3 )? (b) what is it in cubic miles (mi3 )? (c) what is it in cubic centimeters (cm3 )?

Step-by-step explanation:

Volume of earth = 1021 m³

a) 1 km = 1000 m

    1 m = 10⁻³ km

     Volume of earth = 1021  x (10⁻³)³ = 1.021 x 10⁻⁶ km³

     Volume of earth = 1.021 x 10⁻⁶ km³

b) 1 mile = 1600 m

    1 m = 6.25 x 10⁻⁴ miles

     Volume of earth = 1021  x (6.25 x 10⁻⁴)³ = 2.49 x 10⁻⁷ mile³

     Volume of earth = 2.49 x 10⁻⁷ mile³

c)   1 m = 100 cm

     Volume of earth = 1021  x (100)³ = 1.021 x 10⁹ cm³

     Volume of earth = 1.021 x 10⁹ cm³

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

i think it is c hope that
