a. What are the coordinates of the initial value?
b. What does the initial value represent in this context?
C. What does the rate of change represent in this context?
d. How long does it take the barrel to empty?​

a. What are the coordinates of the initial value?

Step-by-step explanation:

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

( give brainliest)

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
