The population of a certain species of bird in a region after t years can be modeled by the function P(t)= 1620/1+1.15e^-0.042t
natka813 [3]

Answer:

A

Step-by-step explanation:

The function is  \frac{1620}{1+1.15e^{-0.042t}}

To find the maximum population, we need to set t towards infinity to get our answer.

So, we replace time with maximum (\infty). Let's check:

\frac{1620}{1+1.15e^{-0.042t}}\\=\frac{1620}{1+\frac{1.15}{e^{0.042t}}}\\=\frac{1620}{1+\frac{1.15}{e^{0.042(\infty)}}}\\=\frac{1620}{1+\frac{1.15}{\infty}}\\=\frac{1620}{1+0}\\=\frac{1620}{1}\\=1620

The population of birds approaches 1620 as t goes towards infinity. So we can say the max population of the species is 1620.

Correct answer is A

Jug can type 128 words in 3 minutes. How many minutes will it take him to type 576 words
KATRIN_1 [288]

Answer:

13.5 minutes

Step-by-step explanation:

\frac{3 min }{128 words} = \frac{xmin}{576 words}

Cross multiply

3 × 576 = 128x

3 × 576 = 1,728

1,728 = 128x

1,728 ÷ 128 = x

13.5 = x
