Answer:
0.0000625
Step-by-step explanation:
600,000 km²
Using the exponential regression calculator : the regression fit obtained for the data is :
36510 * (1.08^x)
After 40 years ;
x = 40
Hence,
y = 36510 * 1.08^40
y = 36510 * 21.72452
y = 793,162.27 km
Hence, y is closest to 800,000 km
6:4
3 x 2 = 6
2 x 2 = 4
