1) Solve the following first-order linear differential equation: dy dx + 2y = x² + 2x 2) Solve the following differential equation reducible to exact: (1-x²y)dx + x²(y-x)dy = 0
Answers
To solve the first-order linear differential equation dy/dx + 2y = x² + 2x, we can use an integrating factor. Multiplying the equation by the integrating factor e^(2x), we obtain (e^(2x)y)' = (x² + 2x)e^(2x). Integrating both sides, we find the solution y = (1/4)x³e^(-2x) + (1/2)x²e^(-2x) + C*e^(-2x), where C is the constant of integration.
For the exact differential equation (1 - x²y)dx + x²(y - x)dy = 0, we determine that it is exact by checking that the partial derivatives are equal. Integrating the terms individually, we have x - (1/3)x³y + g(y), where g(y) is the constant of integration with respect to y. Equating the partial derivative of g(y) with respect to y to the remaining term x²(y - x)dy, we find that g(y) is a constant. Hence, the general solution is given by x - (1/3)x³y + C = 0, where C is the constant of integration.
For the first-order linear differential equation dy/dx + 2y = x² + 2x, we multiply the equation by the integrating factor e^(2x) to simplify it. This allows us to rewrite the equation as (e^(2x)y)' = (x² + 2x)e^(2x). By integrating both sides, we obtain the solution for y in terms of x and a constant of integration C.
In the case of the exact differential equation (1 - x²y)dx + x²(y - x)dy = 0, we check the equality of the partial derivatives to determine its exactness. After confirming that the equation is exact, we integrate the terms individually with respect to their corresponding variables. This leads us to a solution that includes a constant of integration g(y). By equating the partial derivative of g(y) with respect to y to the remaining term, we determine that g(y) is a constant. Consequently, we express the general solution in terms of x, y, and the constant of integration C.

Answers
Using Rank theorem , the dimensions of col A and Null A add up to the number of colmns in A. It is true statement.
The rank of matrix A denoted as rank(A) is the dimension of the column space Col(A).
The nullity of matrix A written as nullity(A) is the dimension of the null space Nul(A)
Rank Theorem:
If A is a matrix with n columns, then
Rank (A) + nullity (A) = n
In other words we can say that
dim (Col(A) ) in column space + dim (Nul(A)) in empty space = total number of columns in A
The rank theorem is really important theorem.
It is gives a strong relationship between the Null space ( all possible vector x such that Ax = 0) and the column space (the set of vectors b matching Ax=b) explain the two main objectives. The more freedom we have for choosing x, the less freedom we have for choosing b, and vice versa.

Susan had four bags of candy, each weighing 6 ounces. Isabel had one bag of candy weighing 1 pounds. Which girl has the more candy in weight? Your work will justify your answer.
Answers
Susan has more candy in weight compared to Isabel.
To compare the candy weights between Susan and Isabel, we need to ensure that both weights are in the same unit of measurement. Let's convert Isabel's candy weight to ounces for a fair comparison.
Given:
Susan: 4 bags x 6 ounces/bag = 24 ounces
Isabel: 1 bag x 16 ounces/pound = 16 ounces
Now that both weights are in ounces, we can see that Susan has 24 ounces of candy, while Isabel has 16 ounces of candy. As a result, Susan is heavier on the candy scale than Isabel.

Similar to 3.4.2 in Rogawski Adams Find the ROC of the volume of a cube with respect to the length of its side s when 8 = 3 d/ds (volume)|s=3 = _____ cubic units per unit increase of side length.
Answers
The ROC of the volume of a cube with respect to the length of its side is s > 0. The given rate of change of volume with respect to side length does not affect the calculation of ROC.
The volume of cube is given by V = s^3, where s is the length of its side.
Taking the derivative of V with respect to s, we get:
dV/ds = 3s^2
The rate of change of volume with respect to the length of the side s is given as:
dV/ds = 8
Substituting the value of dV/ds and solving for s, we get:
8 = 3s^2
s^2 = 8/3
s = ±√(8/3)
Since the length of side of a cube cannot be negative, we take the positive root:
s = √(8/3)
The radius of convergence (ROC) of the volume is s > 0, which means the series expansion of the volume of the cube in terms of the length of its side converges for values of s greater than zero.
Therefore, the ROC is s > 0.
The rate of change of volume does not affect the change in the calculation of ROC.

Answers
According to the question the function over the interval \(\([-1, 2]\)\) to find the area of the region.
1. Find the points of intersection by setting \(\(f(y) = g(y)\)\) and solving for \(\(y\)\).
\(\(y^2 = y + 2\)\)
Rearranging, we get \(\(y^2 - y - 2 = 0\)\)
Factoring, we have \(\((y - 2)(y + 1) = 0\)\)
So the points of intersection are \(\(y = 2\) and \(y = -1\).\)
2. Sketch the graphs of the functions \(\(f(y) = y^2\) and \(g(y) = y + 2\)\) on a coordinate plane.
3. Shade the region bounded by the two graphs between the points of intersection.
4. Calculate the area of the shaded region using definite integration:
\(\(\text{Area} = \int_{-1}^{2} (f(y) - g(y)) \, dy\)\)
To evaluate the integral and find the area of the region between the graphs of \(\(f(y) = y^2\) and \(g(y) = y + 2\)\), we need to integrate the difference between the two functions over the given interval.
The interval of integration is \(\([-1, 2]\)\), which corresponds to the points of intersection.
Using definite integration, we have:
\(\(\text{Area} = \int_{-1}^{2} (f(y) - g(y)) \, dy = \int_{-1}^{2} (y^2 - (y + 2)) \, dy\)\)
Simplifying the integrand, we get:

both methods requires two initial guesses x1 and x2, and it is necessary that f(x1)*f(x2) < 0
Answers
The requirement f(x1) * f(x2) < 0 for choosing initial guesses x1 and x2 with opposite signs ensures the validity and convergence of certain numerical root-finding methods such as the bisection method or the regula falsi method.
The statement you provided is true for certain numerical methods used to find roots of equations, such as the bisection method or the regula falsi method. These methods are iterative and require an initial interval or range where the root is expected to be found. To ensure convergence and a valid solution, it is necessary to choose initial guesses x1 and x2 such that the function f(x) evaluated at those points have opposite signs, i.e., f(x1) * f(x2) < 0.
The rationale behind this requirement is based on the Intermediate Value Theorem, which states that if a continuous function f(x) changes sign over an interval [x1, x2], then there exists at least one root within that interval. By ensuring that f(x1) and f(x2) have opposite signs, we guarantee the existence of a root within the interval [x1, x2].
The bisection method works by repeatedly bisecting the interval and selecting a new subinterval that contains the root. At each iteration, the method narrows down the interval by halving it, based on the sign change observed in the function evaluations.
Similarly, the regula falsi (or false position) method also operates by iteratively refining the interval based on the linear interpolation between the function values at the endpoints. The method adjusts the interval based on the sign change of the function, converging to the root.
Both methods rely on the property of opposite signs to guarantee convergence and avoid getting stuck in a non-converging or incorrect solution. If the initial guesses do not satisfy the condition f(x1) * f(x2) < 0, it is possible that the method fails to converge or converges to a different root or solution.

Let P be the profit made (in dollars). Write an equation relating P to N. Simplify your answer as much as possible
Answers
If The total revenue earned (in dollars) from selling the books is given by the function R-34.60N. the equation relating P to N is P = 18.95N - 750.
Profit made (P) can be calculated by subtracting the total production cost (C) from the total revenue earned (R), so:
P = R - C
P = 34.60N - (18.95N + 750)
P = 34.60N - 18.95N - 750
P = 15.65N - 750
Therefore, the equation relating P to N is P = 18.95N - 750.
The equation shows that the profit made by the company is a linear function of the number of books printed. The slope of the line is the revenue per book (34.60 dollars), minus the cost per book (18.95 dollars), which is 18.95 dollars.
The intercept of the line is the fixed cost for editing (750 dollars). The equation can be used to estimate the profit for any given number of books printed, and to determine the break-even point, which is the number of books that need to be sold to cover the total production cost.

An office supply company ordered 24 cartons of specialty paper. The regular price for a carton of specialty paper is $6.88. They received a discount of $1.75 off each carton. About how much money will the office supply company need to pay for the paper? Which of the expressions gives a reasonable estimate of the answer? A. $5 × 25 B. $6 × 25 C. $7 × 20 D. $9 × 30
Answers
Answer: A. $5 × 25
Step-by-step explanation:
Given the following :
Number of cartons of specialty paper ordered = 24 cartons
Regular price for a carton = $6.88
Discount given off each carton = $1.75
Hence,
Discounted price per carton = $(6.88 - 1.75) = $5.13
Actual amount to be paid for the order :
Discounted price * number of cartons to be ordered
$5.13 * 24
Hence, a reasonable estimate will be :
$5.13 = $5( nearest whole number)
24 can be rounded to 25 (this covers for the $0.13 on the discounted cost per carton)
Reasonable estimate :
$5 × 25
Answer:
The answer is A. $5 × 25
Step-by-step explanation:
Given that the total number of cartons is 24
the price per carton originally is $6.88
the discount is $1.75
hence the company will have to pay 6.88-1.75= $5.13
hence the price per carton upon removal of the discount is $5.13
for all 24 cartons, the company will have to pay 24*5.13
A reasonable estimate from the given option is

The probability that x is between 420 and 460 is 0.25778
The sum of independent normally distributed random variables is normally distributed with mean equal to the sum of the individual means and variance equal to the sum of the individual variances.
so, the mean would be,
μ = 100 + 150 + 200
μ = 450

σ = 15+ 20 + 25
σ = 60
We need to find the probability that x is between 420 and 460.
P(420 < x < 460)
= P( 420 - μ < x - μ < 460 - μ)
= P((420 - μ)/σ < (x - μ)/σ < (460 - μ)/σ)
= P((420 - 450)/60 < Z < (460 - 450)/60)
= P (-1/2 < Z < 1/6)

Solution:
Before you solve this question, remember this identity of the cube of a binomial.\((a + b) ^{3} = {a}^{3} + {b}^{3} + 3ab(a + b) \\ \)
Here, we have to find the cube of (x + 2).Replacing a by x and b by 2 in the above identity, we have\((x + 2) ^{3} \\ = {(x)}^{3} + (2) ^{3} + 3 \times x \times 2(x + 2) \\ = {x}^{3} + 8 + 6x(x + 2) \\ = {x}^{3} + 8 + 6x \times x + 6x \times 2 \\ = {x}^{3} + 8 + {6x}^{2} + 12x\)
Now, arrange the above expression in standard form.\( = {x}^{3} + {6x}^{2} + 12x + 8 \\ \)
Answer:
\({x}^{3} + {6x}^{2} + 12x + 8\)
Hope you could understand.
If you have any query, feel free to ask.
Given:
\((x + 2)^{3} \)
Now using algebraic identities,
\( {x}^{3} + 3(x)^{2} + 3(x)(2)^{2} + {2}^{3}\)
\( = > {x}^{3} + 3(x)^{2} + 3(x)(2)^{2} +8\)
\( = > {x}^{3} + 6x^{2} +12x +8\)

Orpheus needs a new cat lounge. The pet store has one in stock that Orpheus likes for $33. The local sales tax rate is 4.25% where Orpheus lives. The store is running a clearance event on cat furniture with discounts of forty percent off.
Answers
Answer:
$20.64
Step-by-step explanation:
When you take 40% of 33, you are left with 19.8. You then translate the sales tax into 84 cents and add it to 19.8. That will give you $20.64 as the after tax price.
