math

A Petri dish containing 500,000 bacteria is used in an experiment investigating growth rates for bacteria. The table below shows the number of bacteria, N(t), in the Petri dish after t minutes.

t N(t)
1 520,000
2 540,800
3 562,432

Select the equation that models N(t).

N(t)=500,000(1.04)tcap n times t is equal to 500 comma 000 1 point 0 4 to the t th power , ,

N(t)=520,000+1.04(t−1)cap n times t is equal to 520 comma 000 plus 1 point 0 4 raised to the open paren t minus 1 close paren power

N(t)=520,000(1.04)tcap n times t is equal to 520 comma 000 1 point 0 4 to the t th power , ,

N(t)=500,000(1.04)t−1

  1. 520/500 = 1.04
    since N(1) = 500K * 1.04^1, it sure looks like
    N(t) = 500K * 1.04^t
    if you can match that with any of those horribly typed choices, go for it.
