Hi!

The smallest value of k can be <u>0</u> or <u>9</u>

Explanation :-

For your question, there will be two possible answers, which means that, k can be 882<u>9</u> and 882<u>0</u> .

It is allowed to write any one number out of these two as any number ending with 0 or 9 are perfect cubes.

Hence, the answer will be 882<u>0</u> or 882<u>9</u>

-----------------☆----------------

Hint :-

882 = 2×3²×7². By trying to get to 2³×3³×7³ = (2×3×7)³. In other words, figure out what is missing that k needs to be so that you arrive at (2×3×7)³

Or put another way, you want to solve 882×k = (2×3×7)³

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
