Under ideal conditions a certain bacteria population is
known to double every three hours. suppose that there are
initially 100 bacteria.
(a) what is the size of the population after 15 hours?
(6) what is the size of the population after { hours?
(c) estimate the size of the population after 20 hours.
(d) graph the population function and estimate the time for
the population to reach 50,000.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

step-by-step explanation:

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.
