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

In around of golf, the lowest score wins. At the end of a round you have score -3 and your friend has score -4. Who won the roun
scoray [572]

Answer: The friend won the round.

Step-by-step explanation:

We want to find the lowest score.

The lowest score means the smallest value.

With intergers, as the number gets farther away from zero to the left, the smaller the value is. The middle number is zero on a number line. The numbers to the left of zero are negative. The number to the write of zero are positive.

As you move to the left on the number line, the numbers get smaller. As you move to the right on  a number line, the values get bigger

Since -4 is farther away from zero to the left on a number line than -3, -4 is smaller.

Hence -4 is smaller than -3. -4 is one more to the left than -3 so -4 is smaller than -3.

Hence the friend won the round.

Solve 2(x+3)3/2=54 x = <br>show your work
hjlf

Answer:

x=15

Step-by-step explanation:

Step 1: Multiply both sides by 2.

Step 2: Simplify both sides of the equation.

6x+18=108

Step 3: Subtract 18 from both sides.

6x+18−18=108−18

6x=90

Step 4: Divide both sides by 6.

x=15
