A certain population is modeled by the function P (t) = StartFraction 50,000 Over 1 + 4 e Superscript negative 0.5 t Baseline EndFraction. How long will it take for the population to reach 30,000 organisms? approximately 0.4 years
approximately 0.8 years
approximately 3.6 years
approximately 8.1 years

The answer is C. 3.6 years on edge

i dont understand the question? ?

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

the answer is 21%.
