Suppose that an insect population’s density, in thousands per acre, during year n, can be modeled by the recursive formula: a1 =

vlabodo [156]

Answer:

The population alternates between increasing and decreasing

Step-by-step explanation:

<u><em>The options of the question are</em></u>

A) The population density decreases each year.

B) The population density increases each year.

C) The population density remains constant.

D) The population alternates between increasing and decreasing

we have

$a_n=2.9(a_n_-_1)-0.2(a_n_-_1)^2$

$a_1=8$

Find the value of $a_2$

For n=2

$a_2=2.9(a_1)-0.2(a_1)^2$

$a_2=2.9(8)-0.2(8)^2=10.4$

Find the value of $a_3$

For n=3

$a_3=2.9(a_2)-0.2(a_2)^2$

$a_3=2.9(10.4)-0.2(10.4)^2=8.528$

For n=4

$a_4=2.9(a_3)-0.2(a_3)^2$

$a_4=2.9(8.528)-0.2(8.528)^2=10.1858$

For n=5

$a_5=2.9(a_4)-0.2(a_4)^2$

$a_5=2.9(10.1858)-0.2(10.1858)^2=8.7887$

therefore

The population alternates between increasing and decreasing

For each equation, find y when x=-3. Then find x when y = 2<br> 1. y = 6x + 8

crimeas [40]

<u><em>⬇ Hey, the answer is down below! :) ⬇</em></u>

<u><em>For y:</em></u> x = -3

For y it stays the same.

<u><em>For x:</em></u> y = 2

For x it stays the same too.

<u><em>For 1.):</em></u> $x = \frac{1}{6}y + \frac{-4}{3}$

Step-by-step explanation:

<u><em>For y there is no step-by-step explanation unfortunately.</em></u>

<u><em>For x there isn't a step-by-step explanation too unfortunately.</em></u>

<u><em>⬇ For 1.) there is a step-by-step explanation! ⬇</em></u>

For step 1 we should flip the equations.

6x + 8 = y

For step 2 we should add -8 to both sides.

6x + 8 + − 8 = y + −8

= 6x = y − 8

For step 3 we should divide both sides by 6.

$\frac{6x}{6} = \frac{y - 8}{6}$

= x = $x = \frac{1}{6}y + \frac{-4}{3}$

<u><em>In result we should have</em></u> $x = \frac{1}{6}y + \frac{-4}{3}$ <u><em>as the answer!</em></u>
