A rare species of insect was discovered

in the Amazon Rain Forest. To protect the species,

environmentalists declared the insect endangered and

transplanted the insect into a protected area. The population P of the insect t months after being transplanted is

P(t)=50(1+0.5t)2+0.01t

(a)

How many insects were discovered? In other words,

what was the population when t = 0?

(b) What will the population be after 5 years?

(c) Determine the horizontal asymptote of P(t). What

is the largest population that the protected area can

sustain?

Short Answer

Expert verified

(a) 25 insects

(b) 596.15 insects

(c) Horizontal asymptote is P=2500, Maximum population is 2500 insects

Step by step solution

01

Part (a) Step 1. Given

The population P of the insect t months after being transplanted is

P(t)=50(1+0.5t)2+0.01t

02

Part (a) Step 2. Calculation

Substituting the value of t in the equation

P(t)=50(1+0.5t)2+0.01tt=0=50(1+0.5×0)2+0.01×0=25

03

Part (b) Step 1. Given

The population P of the insect t months after being transplanted is

P(t)=50(1+0.5t)2+0.01t

04

Part (b) Step 2. Calculation

Substituting the value of t in the equation

P(t)=50(1+0.5t)2+0.01tt=5years=5(12)months=60P(t)=50(1+0.5t)2+0.01t=50(1+0.05×60)2+0.01×60=596.15

05

Part (c) Step 1. Given

The population P of the insect t months after being transplanted is

P(t)=50(1+0.5t)2+0.01t

06

Part (c) Step 2. Calculation

Here, n=1,m=1

therefore, for finding horizontal asymptote we use the formula

role="math" localid="1646174992788" anbmi.e.P=anbmP(t)=50(1+0.5t)2+0.01t=25t+500.01t+2thereforean=25bm=0.01=250.01=2500

The largest population that the protected area can sustain is the population we get when t is large and this can be arbitrarily close to the horizontal asymptote

i.e. 2500 insect.

From Ohm’s law for circuits,

it follows that the total resistance Rtotof two components connected in parallel is given by the equation

Rtot=R1R2R1+R2

where R1,R2are individual resistance.
