One method of slowing the growth of an insect population without using pesticides is to introduce into the population a number of sterile males that mate with fertile females but produce no offspring. Let P represent the number of female insects in a population and S the number of sterile males introduced each generation. Let r be the per capita rate of production of females by females, provided their chosen mate is not sterile. Then the female population is related to time t by
Answer:
P + S / P [(r - 1) P - S] dP
Step-by-step explanation:
If r = 0.10 and S = 900 then,
P + 900 / P [(0.10 - 1) P - 900] dP
Solving the equation we get,
P + 900 = (B - 0.9A)P - 900A
If A = -1,
B = 0.10
t = 0 and P = 10,000
ln 10000 - 1 /9 ln (0.9 * 10000 + 900) + C
C = 10.2326.

Find the average rate of change of g ( x ) = 5 x 3 + 4 from x = − 1 to x = 3
Answer:
Go to symbolab.com, online calculator, so good trust me
Step-by-step explanation:
The average rate of change of [tex]g ( x ) = 5 x^3 + 4[/tex] from x = − 1 to x = 3 is 35.
What is average rate of change of function?"It is a measure of how much the function changed per unit, on average, over that interval."
What is the formula average rate of change of function?The average rate of change of function f over the interval a ≤ x ≤ b, is given by this expression: [tex]\frac{f(b)-f(a)}{b-a}[/tex]
For given question,
We have been given a function [tex]g ( x ) = 5 x^3 + 4[/tex]
We need to find the average rate of change of function g(x) from x = − 1 to x = 3
Here, a = -1 and b = 3
[tex]g(a)\\= g(-1)\\=5(-1)^3+4\\=-5+4\\=-1[/tex]
and the value of g(b) is,
[tex]g(b)\\=g(3)\\=5(3)^3+4\\=135+4\\=139[/tex]
Using the formula of average rate of change of function,
[tex]\frac{f(b)-f(a)}{b-a}\\\\=\frac{139-(-1)}{3-(-1)}\\\\=\frac{140}{4}\\\\=35[/tex]
Therefore, the average rate of change of [tex]g ( x ) = 5 x^3 + 4[/tex] from x = − 1 to x = 3 is 35.

Tyler wants to use $300 he has saved to buy a new guitar and join a music club. The guitar costs $140. The music club has a $25 membership fee, and for $11.95 per month, members can download 30 songs. Tyler can afford the music club membership for____ months, after which he will have_____ left.
Answer:
11 months ; $3.55
Step-by-step explanation:
Amount saved = $300
Cost of guitar = $140
Membership fee = $25
Monthly fee = $11.95
For how manyonths can Tyler afford the membership :
The one time fee = (membership fee + cost of guitar)
= $140 + $25 = $165
Amount left = $300 - $165
Amount left = $135
Number of monthly fee the balance can afford :
Amount left / monthly fee
= $135 / $11.95
= 11.29
Hence, the number of months he can pay for is 11 months
Amount left = $135 - ($11.95 * 11 months)
$135 - $131.45
= $3.55

Type the correct answer in each box. Use numerals instead of words. A race car is driven by a professional driver at 99 m/h. What is this speed in km/h and km/min?
1 mile = 1.61 kilometers
1 hour = 60 minutes
Round your answers to the nearest tenth. The speed is equivalent to
( ) km/h,
or ( ) km/min
Answer:
160 kilometers per hour
9560 kilometers per minute
Answer:
Speed of the car is equivalent to 159.39 KM/hour or 2.6565 Km/min.
-Step by Step-:
-The speed of the car is given as 99 mi/hour.
Now, WE know that 1 Mile = 1.61 KM
Hence, in order to calculate the speed of the car in KM/hour we will multiply the speed of the car in miles with 1.61.
⇒The speed of the car in KM/hour = 99 × 1.61 KM = 159.39 KM/hour
Also, 1 hour = 60 minutes
⇒ Speed of the car in KM/min = (159.39) ÷ 60 = 2.6565 K/min

Answer:
288 cu in
Step-by-step explanation:
The Two end pieces
l = 6
w = 4
h = 4
V = l*w*h
V = 6*4*4
V = 96
But there are two end pieces. So the volume for both is 2 * 96 = 192
Middle Piece
L = 8
w = 4
h = 3
Volume = l * w * h
Volume = 8 * 4 * 3
Volume = 96
Total Volume
Total Volume = 96 + 192
Total Volume = 288 Cu in
What is the absolute value of -2 2/3 as a mixed number in simplest form
Answer:
2 2/3

Sergio is working on a research project involving the ages of students at Brooklyn College. After interviewing 500 students, he has determined that the average age of a Brooklyn College student is 20 years and 6 months. He has further determined that the range of ages of the students on campus follows a normal distribution with a standard deviation of 2 years. What is the probability of a randomly chosen student being exactly 21 years old
Answer:
The probability of of a randomly chosen student being exactly 21 years old.
= 1.293
Step-by-step explanation:
Step(i):-
Given Population size n = 500
Mean of the Population = 20 years and 6 months
= [tex]20 + \frac{6}{12} = 20 +0.5 = 20.5 years[/tex]
Standard deviation of the Population = 2 years
Let 'X' be the range of ages of the students on campus follows a normal distribution
Let x =21
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{x-mean}{S.D} = \frac{21-20.6}{2} =0.2[/tex]
The probability of a randomly chosen student being exactly 21 years old.
P( Z≤21) = 0.5 + A( 0.2)
= 0.5 +0.793

Jada can read 3/5 of a book in 1/4 of an hour. How long would it take her to read one whole
book?
Answer:
25 Minutes
Step-by-step explanation:
Well, 1/4 of an hour is obviously 15 minutes. So if she read 3/5 of the book in 15 minutes, you have to find how long it took her to read 1/5 of the book. If 15 minutes is 3/5, then 15/3 is 5, which is the time it took to read 1/5 of the book. You add 10 to 15 and you get 25. I hope this helps!
If Jada can read 3/5 of a book in 1/4 of an hour, it will take her 5/12 of an hour to read one whole book
Time taken to read 3/5 of the book = 1/4 hours
To get the time taken to read 1 book, we will divide 1/4 hours by 3/5
Time taken to read 1 book = [tex]\frac{1}{4}\div \frac{3}{5}[/tex]
The division sign changes to multiplication and 3/5 is changed to its reciprocal (5/3)
Time taken to read 1 book = [tex]\frac{1}{4}\times\frac{5}{3}[/tex]
Time taken to read 1 book = [tex]\frac{5}{12}[/tex]
If Jada can read 3/5 of a book in 1/4 of an hour, it will take her 5/12 of an hour to read one whole book

B. The product of two irrational numbers can be rational or irrational.
C. The product of two irrational numbers is always irrational.
D. The product of two irrational numbers cannot be determined.
Answer:
B. The product of two irrational numbers can be rational or irrational.
Step-by-step explanation:
An irrational number is a number that is real and it cannot be written or expressed as a fraction.
For example , 2√3, √5 are irrational numbers.
A rational number is a number that is real and can be expressed as a fraction. It is a whole number. For example: 5, 7 are rational numbers

a) √2•√2 = √2 × √2 = √4 = 2 = rational number
b) √5•√7 = √5 × √7 = √35 = Irrational number
c) √2•18 = √2 × 18 = 18√2 = Irrational number
d) √2•√6 = √2 × √6 = √12 = Irrational number.
My conclusion from the above results is option B, which states that
