A city’s population has been growing linearly. In 2008, the population was 28,200. By 2012, the population was 36,800. Assume this trend continues. Let p(x) = population, and x = years since 2012. Answer the questions. -Expected Population in year 2014 =
- Predicted year when population will reach 54000 =
- The rate of population changes = ?
- The number of years for the population doubled since 2008 =
Using the equation, we found the following:
1) Expected Population in the year 2014 = 41100
2) Predicted year when the population will reach 54000 = 2020
3) The rate of population changes = 2150
4) The number of years for the population doubled since 2008 =9.12
What is a linear equation?
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant.
Given,
the population in 2008 = 28,200
the population in 2012 = 36,800
The population is growing linearly.
Assume a linear equation,
p(x) = 36800 + kx
where,
p(x) = population
x = years since 2012.
k = increase in population
p(0) = 36800
p(-4) = 36800 - 4k
28200= 36800 -4k
4k = 36800 - 28200
k = 2150
Then the linear equation becomes,
p(x) = 36800 + 2150x
1) Population in 2014
x = 2014 - 2012 = 2
From the equation,
p(2) = 36800 + 2150 * 2 = 41100
2) x when p(x) = 54000
From the equation,
54000 = 36800 + 2150x
2150x = 17200
x = 8
Year = 2012 + 8 = 2020
3) Rate of population change = (population in 2012 - population in 2008) / number of years = 36800-28200 / 4 = 2150
4) Population doubled since 2008
p(x) = 2 * 28200 = 56400
We have to find x , when p(x) = 56400
Using the linear equation,
56400 = 36800 + 2150x
x = 9.12
Therefore using the equation, we found the following:
1) Expected Population in the year 2014 = 41100
2) Predicted year when the population will reach 54000 = 2020
3) The rate of population changes = 2150
4) The number of years for the population doubled since 2008 =9.12

Alan and Ben had collected 360 game cards altogether. They played three games using these cards. In the first game, Alan lost 2 /5 of his cards to Ben. In the second game, Alan won 1 /4 of Ben cards. In the last game, Alan lost 1 /6 of his cards to Ben. In the end, both boys had the same number of cards. How many game cards did each boy have at first?
Answer:
Alan had 272 cards initially and Ben had 88 cards initially.
Step-by-step explanation:
Let's start by assuming that Alan had x cards and Ben had y cards initially. We know that the sum of their cards is 360, so:
x + y = 360
In the first game, Alan lost 2/5 of his cards to Ben, so he gave away (2/5)x cards to Ben. Therefore, he was left with:
(3/5)x cards
Ben received (2/5)x cards from Alan and had y cards initially, so he had:
y + (2/5)x
cards after the first game.
In the second game, Alan won 1/4 of Ben's cards, so he received (1/4)(y + (2/5)x) cards. Therefore, he had:
(3/5)x + (1/4)(y + (2/5)x)
cards after the second game.
In the third game, Alan lost 1/6 of his cards to Ben, so he gave away (1/6)(3/5)x cards to Ben. Therefore, he was left with:
(2/3)(3/5)x = (2/5)x
cards.
Ben received (1/6)(3/5)x cards from Alan in the third game, and he had y + (2/5)x cards after the first game. Therefore, he had:
y + (2/5)x + (1/6)(3/5)x = y + (9/25)x
cards after the third game.
Since both boys ended up with the same number of cards, we can set the expressions for their final card counts equal to each other:
(3/5)x + (1/4)(y + (2/5)x) = y + (9/25)x
Multiplying both sides by 100 to get rid of the fractions, we get:
60x + 25y + 50x = 100y + 36x
Simplifying, we get:
24x = 75y
Since x + y = 360, we can use this equation to solve for one of the variables in terms of the other:
x = 360 - y
Substituting into the equation we just obtained, we get:
24(360 - y) = 75y
Simplifying, we get:
8640 - 24y = 75y
99y = 8640
y = 87.27
Since y must be a whole number (since it represents the number of cards that Ben had initially), we can round it up to 88. Substituting into the equation x + y = 360, we get:
x + 88 = 360
x = 272
Therefore, Alan had 272 cards initially and Ben had 88 cards initially.
To find the initial number of game cards Alan and Ben had, we can set up an equation and solve for a variable. The equation involves using the information about the games played and the number of cards lost and gained by Alan. The solution will give us the initial numbers of cards for both boys.
Explanation:To solve this problem, let's assume that Alan had x cards and Ben had y cards at the beginning. We are given that Alan lost 2/5 of his cards to Ben in the first game, so he had (3/5)x cards left and Ben had y + (2/5)x cards. In the second game, Alan won 1/4 of Ben's cards, so he gained (1/4)(y + (2/5)x) cards, leaving him with (3/5)x + (1/4)(y + (2/5)x) cards. In the last game, Alan lost 1/6 of his cards to Ben, so he had (5/6)((3/5)x + (1/4)(y + (2/5)x)) cards left. Since both boys had the same number of cards in the end, we can set up the equation: (5/6)((3/5)x + (1/4)(y + (2/5)x)) = y + (2/5)x. After simplifying and solving for y in terms of x, we can substitute back into the equation to find the value of x.

n the first week of July, a record 1,120 people went to the local swimming pool. In the second week, 125 fewer people went to the pool than in the first week. In the third week, 145 more people went to the pool than in the second week. In the fourth week, 132 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
First, we need to find the number of people who went to the pool in the second, third, and fourth weeks.
Number of people in second week = 1,120 - 125 = 995
Number of people in third week = 995 + 145 = 1,140
Number of people in fourth week = 1,140 - 132 = 1,008
To find the percent decrease, we need to find the difference between the number of people in the first week and the fourth week, and then divide by the number of people in the first week.
Difference between first and fourth weeks = 1,120 - 1,008 = 112
Percent decrease = (112/1,120) x 100% = 10%
Therefore, the percent decrease in the number of people who went to the pool over these four weeks is 10%.
PRESENT AND FUTURE VALUES OF A CASH FLOW STREAMAn investment will pay $150 at the end of each of the next 3 years, $250 at the end of Year 4, $300 at the end of Year 5, and $500 at the end of Year 6. If other investments of equal risk earn 11% annually, what is its present value? Its future value?
Answer:
Step-by-step explanation:
To calculate the present value (PV) and future value (FV) of the cash flow stream, we can use the following steps:
Calculate the present value of each cash flow using the formula:
PV = CF / (1 + r)^n
where CF is the cash flow, r is the annual interest rate, and n is the number of years until the cash flow is received.
For the first three cash flows of $150 at the end of each of the next 3 years, assuming a starting point of Year 0, we have:
PV1 = $150 / (1 + 0.11)^1 = $134.59 (Year 1)
PV2 = $150 / (1 + 0.11)^2 = $120.75 (Year 2)
PV3 = $150 / (1 + 0.11)^3 = $107.99 (Year 3)
For the cash flow of $250 at the end of Year 4:
PV4 = $250 / (1 + 0.11)^4 = $165.14
For the cash flow of $300 at the end of Year 5:
PV5 = $300 / (1 + 0.11)^5 = $179.34
For the cash flow of $500 at the end of Year 6:
PV6 = $500 / (1 + 0.11)^6 = $277.12
Add up the present values of each cash flow to find the present value of the entire stream:
PV = PV1 + PV2 + PV3 + PV4 + PV5 + PV6
PV = $134.59 + $120.75 + $107.99 + $165.14 + $179.34 + $277.12
PV = $985.93
Therefore, the present value of the cash flow stream is $985.93.
To find the future value of the cash flow stream, we can simply add up the cash flows and then apply the future value formula:
FV = CF x [(1 + r)^n - 1] / r
where CF is the sum of the cash flows, r is the annual interest rate, and n is the number of years from the present until the future value is calculated.
CF = $150 x 3 + $250 + $300 + $500 = $1,100
n = 6 (assuming a starting point of Year 0)
FV = $1,100 x [(1 + 0.11)^6 - 1] / 0.11
FV = $2,525.72
Therefore, the future value of the cash flow stream is $2,525.72.

Solve the given differential equation by variation of parameters. x2y'' − 3xy' + 3y = x^4'*e^x
Answer:
Step-by-step explanation:
To solve the differential equation x^2y'' − 3xy' + 3y = x^4e^x using variation of parameters, we can follow these steps:
Step 1: Find the complementary solution y_c by solving the homogeneous equation:
x^2y'' − 3xy' + 3y = 0
The characteristic equation is r(r-1) - 3r + 3 = 0, which simplifies to r^2 - 4r + 3 = 0. Factoring, we get (r-1)(r-3) = 0, so the roots are r=1 and r=3. Therefore, the complementary solution is:
y_c = c1x + c2x^3
where c1 and c2 are arbitrary constants.
Step 2: Find the particular solution y_p using variation of parameters. We assume that the particular solution has the form:
y_p = u1(x)*y1(x) + u2(x)*y2(x)
where y1 and y2 are solutions to the homogeneous equation (in this case, y1=x and y2=x^3) and u1 and u2 are functions to be determined.
We need to find the derivatives of y1 and y2:
y1' = 1, y1'' = 0
y2' = 3x^2, y2'' = 6x
Substituting into the differential equation and simplifying, we get:
x^2(u1''y1 + u2''y2) + x(u1'y1 + u2'y2) = x^4e^x
Plugging in y1 and y2 and simplifying, we get:
x^2(u1''*x + u2''*x^3) + x(u1'*1 + u2'*3x^2) = x^4e^x
We can write this equation in matrix form as:
[x^2x, x^2x^3] * [u1'', u2''] + [x1, x3x^2] * [u1', u2'] = [0, x^4e^x]
Taking the determinant of the coefficient matrix [x^2x, x^2x^3; x1, x3x^2], we get:
(x^2x)(x3x^2) - (x^2x^3)*x = 2x^4
Therefore, the inverse of the coefficient matrix is:
[3x, -x^3] / (2x^4)
Multiplying by the column vector [0, x^4e^x] gives:
[u1', u2'] = [3x, -x^3] * (1/(2x^4)) * [0, x^4e^x]
Simplifying, we get:
u1' = (3/2)*e^(-x), u2' = -(1/2)xe^(-x)
Integrating u1' and u2' with respect to x, we get:
u1 = -(3/2)*e^(-x), u2 = -(1/2)*xe^(-x) + C
where C is an arbitrary constant.
Therefore, the particular solution is:
y_p = -(3/2)xe^(-x) + Cx^3e^(-x)
where C is an arbitrary constant.
Step 3: The general solution of the differential equation is the sum of the complementary solution and the particular solution:
y = y_c + y_p

The expectation is that investors will receive only 50% of face value at maturity. If they buy the bond today, what yield to maturity do they expect to receive?
A. The price of the bond is $556.25.
B. The yield to maturity expected by investors is 20.36%.
What is YTM?Yield to maturity (YTM) is the total rate of return that will have been earned by a bond when it makes all interest payments and repays the original principal.
here, we have,
A. The price of the bond is calculated using the formula:
P = C × (1 − (1 + YTM/2)−2T ) ÷ (YTM/2) + (1 + YTM/2)−2T
Here, C is the coupon payment, YTM is the yield to maturity and T is the time to maturity in years.
Face value = $1,000
YTM = 8.2%
Time to maturity = 7 years
Coupon payment = 8.2% × $1,000 = $82
Substituting these values in the formula, we get:
P = $82 × (1 − (1 + 0.082/2)−14 ) ÷ (0.082/2) + (1 + 0.082/2)−14
P = $82 × (1 − 0.6774) ÷ 0.041 + 0.6774
P = $556.25
B. The yield to maturity expected by investors is calculated using the formula:
YTM = 2 × (C × (1 + YTM/2)−2T + (FV − P) × (1 + YTM/2)−2T ) ÷ P
Here, C is the coupon payment, YTM is the yield to maturity, FV is the face value of the bond and P is the price of the bond.
Expected face value at maturity = 85% × $1,000 = $850
Substituting these values in the formula, we get:
YTM = 2 × ($82 × (1 + YTM/2)−14 + ($850 − $556.25) × (1 + YTM/2)−14 ) ÷ $556.25
YTM = 2 × ($82 × (1 + YTM/2)−14 + ($293.75) × (1 + YTM/2)−14 ) ÷ $556.25
YTM = 2 × ($82 × 0.6774 + ($293.75) × 0.6774) ÷ $556.25
YTM = 2 × ($55.35 + ($198.57) ) ÷ $556.25
YTM = 2 × $253.92 ÷ $556.25
YTM = 0.2036 = 20.36%

√49 is a rational number. √50 is an irrational number. √127 is an irrational number. 125 is a rational number because it is equal to a perfect cube of the whole number 5.
What does an irrational number look like?A real number is considered to be irrational if it cannot be written as a simple fraction. It cannot be described using a ratio. When p and q are numbers and q is not identical to 0, N is not equivalent to p/q if N is irrational. An illustration of this is the illogic of the integers
Why are certain numbers irrational?A actual number that's unable to be written as the ratio between two integers—that is, as p/q, where both p and q both are integers—is an irrational number.
√49 is a rational number because it is equal to 7, which is a whole number.
√50 is an irrational number because it cannot be expressed as a fraction of two integers and it is not a perfect square.
√127 is also an irrational number because it cannot be expressed as a fraction of two integers and it is not a perfect square.
125 is a rational number because it can be expressed as 5^3, which is a perfect cube of the whole number 5.
Therefore, the correct statements are:
√49 is a rational number.

The missing angles inscribed in the circle are
∠ C = 26 degrees∠ B = 26 degrees∠ BSD = 97 degrees∠ CSE = 97 degrees∠ E = 57 degreesHow to find the anglesThe angles are calculated using the inscribed angle theorem
Inscribed Angle Theorem: The measure of an inscribed angle is half the measure of the intercepted arc.
This is used as follows
∠ C = 52/2 degrees
∠ C = 26 degrees
∠ C = ∠ B = 26 degrees inscribed angle subtended by same arc are equal
∠ BSD + ∠ D + B = 180 degrees sum of angles in a triangle
∠ BSD + 57 + 26 = 180
∠ BSD = 180 - 57 - 26
∠ BSD = 97 degrees
∠ CSE = ∠ BSD vertical angles
∠ CSE = 97 degrees
∠ E = ∠ B = 57 degrees inscribed angle subtended by same arc are equal

Shawn's coin collection contained 25 quarters, 20 dimes, 50 pennies, and 5 nickels. What was the
ratio of quarters to the total number of coins?
1. 04:1
2. 100 to 25
3. 1/4
4. 25: 1,000
The ratio of quarters to the total number of coins is 25:100, or simplified to 1:4.
What is the ratio and proportion ?
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as 1 : 3 (for every one boy there are 3 girls).
To find the ratio of quarters to the total number of coins, we need to first calculate the total number of coins.
Total number of coins = number of quarters + number of dimes + number of pennies + number of nickels
Total number of coins = 25 + 20 + 50 + 5
Total number of coins = 100
Therefore, the total number of coins is 100.
The ratio of quarters to the total number of coins is:
Quarters : Total number of coins
= 25 : 100
= 1 : 4
Hence, the answer is option 3. 1/4.
Therefore, the ratio of quarters to the total number of coins is 25:100, or simplified to 1:4.
