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. answer the following:
1.) at what rate was the amount of oil in the well decreasing when there were 1,800,000 barrels remaining?
2.) when will there be 150,000 barrels remaining?

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
