If f(x) is the total number of bacteria present in a sample after x hours, which of the following statements best describes the meaning of f(2) = 12?

the total number of bacteria present in the sample after 12 hours is 2.
the total number of bacteria present in the sample after 6 hours is 2.
the total number of bacteria present in the sample after 2 hours is 12.
the total number of bacteria present in the sample after 6 hours is 12.

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.
