Answer:
C. 10 times greater
Step-by-step explanation:
every time you move left a number space, the value increases by a multiple of 10x (the opposite is true for moving right)
for example:
1.0
10.0
100.0
<u>1</u><u>0</u><u> </u><u>is </u><u>1</u><u>0</u><u>x</u><u> </u><u>greater </u><u>than </u><u>1</u>
<u>1</u><u>0</u><u>0</u><u> </u><u>is </u><u>1</u><u>0</u><u>x</u><u> </u><u>greater </u><u>than </u><u>1</u><u>0</u><u> </u><u>or </u><u>1</u><u>0</u><u>0</u><u>x</u><u> </u><u>greater </u><u>than </u><u>1</u>
<u>*</u><u>notice </u><u>how </u><u>the </u><u>number </u><u>1</u><u> </u><u>is </u><u>moving </u><u>one </u><u>space </u><u>to </u><u>the </u><u>left</u>
Answer:
V' = -0.11552 *V\\= -0.11552(1.8)\\ \\=-0.20794 million per year
Step-by-step explanation:
Given that oil is pumped continuously from a well at a rate proportional to the amount of oil left in the well. Initially there were 3 million barrels of oil in the well; six years later 1,500,000 barrels remain.
i.e. if V stands for volume of oil, then

To find A and k
V(0) = A = 3 million
Hence V = 
V(6) = 1.5
i.e. 

a) Using the above value of k , we have
million per year.
