11. how far, in centimeters, has the distance between north america and africa increased since you were born? multiply the rate by your age.
cm

12. how much has the distance increased during the average lifetime of 82 years?



13. how much closer were the continents when columbus crossed the atlantic in 1492?

11. (0.7in/yr)*(ft/12in)*19yr = 1.11 ft = 33.8 cm

12. (0.7in/yr)*(ft/12in)*82yr = 4.78 ft = 146 cm

13. (0.7in/yr)*(ft/12in)*527yr = 30.7 ft = 937 cm

Step-by-step explanation:

11. (0.7in/yr)*(ft/12in)*19yr = 1.11 ft = 33.8 cm

12. (0.7in/yr)*(ft/12in)*82yr = 4.78 ft = 146 cm

13. (0.7in/yr)*(ft/12in)*527yr = 30.7 ft = 937 cm

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 : )
