<h2><em><u>EXPLANATION :-</u></em></h2>

= (2 {n}^{2} - 5n - 6) + (  - {n}^{2} - 3n  + 11)

= 2 {n}^{2}  - 5n - 6 -  {n}^{2} - 3n  + 11

= 2 {n}^{2} -  {n}^{2}  - 5n - 3n - 6 + 11

= (n²-8n+5)→Answer

Answer:

We conclude that the percent of decrease = 20%

Step-by-step explanation:

Given

  • Original amount = $3930
  • Amount of decrease = $3930 - $3144 = $786

Using the formula

Percent of decrease = ( amount of decrease / orignal amount × 100 ) %

                                   = ( 786 / 3930 × 100 ) %

                                    = ( 0.2 × 100 ) %

                                    = 20%

Therefore, we conclude that the percent of decrease = 20%

<span>(a) At the end of Month 0, about how many more insects were in Pod A than Pod B? Explain.
In Pod A, the point is higher than 50, it could be 60 to 70 insects. Pod B has 20 insects. So, Pod A has at least 40 insects more than Pod B.

(b) Find and compare the growth rates of each pod. Show your work.
Pod A: (0,60) ; (1,80) ; (2,100) 
(80-60)/60 = 0.33
(100-80)/80 =  0.25

Pod B: (0,20) ; (1,44) ; (2,97)
(44-20)/20 = 1.2
(97-44)/44 = 1.2

Based on my computation, the rate of Pod A is lower than the rate of Pod B. 

(c) When does the population in Pod B exceed the population in Pod A? Explain. 
Pob B exceeds the population of Pod A at the END OF MONTH 4.

Pod A has a population of less than 200 while Pod B has a population of 469.</span>
