Combine like terms.

-14cd + 15cd - 15cd = -14cd
-2c²d² + 9c²d² = 7c²d²

7c²d² - 14cd is your answer

hope this helps

<span>-14cd - 2c²d² + 15cd+9c²d²-15cd
</span><span>= cd(-14 + 15 - 15) + c²d²(-2 + 9)
= </span>7c²d² - 14cd

Hope it helps

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:

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.
