Solve the given differential equation. 3x^2y'' + 6xy' + y = 0
The solution for given differential equation is y = c1e^(-x^3/3) + c2xe^(-x^3/3)
This is a second-order linear differential equation with constant coefficients. To solve this equation, we can use the method of an auxiliary equation, which is 3r^2 + 6r + 1 = 0. This equation has two complex conjugate roots, r = -3 ± i√3. Therefore, the solution of the differential equation is y = c1e^(-x^3/3) + c2xe^(-x^3/3)cos(√3x^2/2) + c3xe^(-x^3/3)sin(√3x^2/2), where c1, c2, and c3 are arbitrary constants.
The method of an auxiliary equation is a popular way to solve second-order linear differential equations with constant coefficients. It involves finding the roots of an auxiliary equation, which is found by setting the coefficient of the second derivative equal to zero.

Answer:
Nina would have total expenses and sales $156 after selling 4 necklaces.
Step-by-step explanation:
Let x represent the amount of necklaces made and sold.
The initial cost was $140 and it costs $4 to produce one necklace. Hence, the total cost after producing x necklaces can be represented as:
\(\displaystyle 140 + 4x\)
Each necklace sells for $39. Hence, the total profit after selling x necklaces can be represented as:
\(\displaystyle 39x\)
To break even, the total cost and profit must be equivalent. Hence:
\(\displaystyle 140 + 4x = 39x\)
Solve for x:
\(\displaystyle \begin{aligned} 140 + 4x & = 39x \\ \\ 140 & = 35x \\ \\ x & = 4 \end{aligned}\)
Hence, the break even, Nina would need to sell four necklaces.
And the total expenses/profit would be:
\(\displaystyle \$39(4) = \$156\)
In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.
Answer:
The total expenses is $156 is the total necklaces sold is 4.Step-by-step explanation:
We know that:
x = Necklaces created and sold140 + 4(x) = Total cost39x = Profit = Total costProfit = Total costWork:
140 + 4x = 39x=> 140 = 39x - 4x=> 140 = 35x=> x = 140/35=> x = 4Now, let's substitute the value of x into any equation to find the total expenses and sales.
140 + 4x => 140 + 4(4)=> 156Hence, the total expenses is $156 is the total necklaces sold is 4.

Step-by-step explanation:
in how many ways can first, second, and third prizes be awarded in a contest with 950 contestants? assume there are no ties.
There are 853,818,600 ways to award first, second, and third prizes in a contest with 950 contestants, assuming there are no ties.
To determine the number of ways to award first, second, and third prizes in a contest with 950 contestants, we can use the permutation formula:
P(n, r) = n! / (n - r)!
where n is the total number of contestants and r is the number of prizes to be awarded (in this case, 3).
Using this formula, we get:
P(950, 3) = 950! / (950 - 3)!
= 950! / 947!
= 950 × 949 × 948
= 853,818,600
Therefore, there are 853,818,600 ways to award first, second, and third prizes in a contest with 950 contestants, assuming there are no ties.

3 quarts of apples juice for $3.59 OR 1 gallon (4 quarts) of apple juice for $3.99
Answer:
1 gallon is the better deal
Step-by-step explanation:
If you divide 3.99/4 you get 0.9975. Therefore, a quart of apple juice costs 0.9975. If you divide 3.59/3, you get 1.19 which is more expensive than 0.9975. The answer is 1 gallon of apple juice for 3.99 is the better deal.

Answer:
\(x=\frac{83}{36}\)
Step-by-step explanation:
1) Convert \(2\frac{1}{4}\) to improper fraction. Use this rule: \(a\frac{b}{c} =\frac{ac+b}{c}\).
\(x-\frac{2\times4+1}{4} = \frac{1}{18}\)
2) Simplify \(2\times4\) to 8.
\(x-\frac{8+1}{4} =\frac{1}{18}\)
3) Simplify \(8+1\) to 9.
\(x-\frac{9}{4} =\frac{1}{18}\)
4) Add \(\frac{9}{4}\) to both sides.
\(x=\frac{1}{18} +\frac{9}{4}\)
5) Simplify \(\frac{1}{18} +\frac{9}{4}\) to \(\frac{83}{36}\).

2π/40t
Explanation:
There are 2π radians in a full rev
2πR/3 Rev/ min = 2/3π minutes per rev
R= 2.0944 min per rev
Period is 2/3π
2π/x = 2/3π
∴ x = 3
∴sin xt = sin 3t
He starts at 3 o'clock position which is 1/2 way between low and high points, so there is no phase shift
Amplitude = 44
44 sin 3t = height above center
Height above ground is shifted by 48 feet up from center
∴ 44 sin (3t) + 48 would be height above ground ( at time = 0 he is 48 ft above ground)

Question 4 Solve. Be sure to check for any extraneous solutions 2ln(x)=ln(4)+ln(16)
The solution is x = 8.
The solution to the equation 2ln(x) = ln(4) + ln(16) should be determined, taking into account any extraneous solutions. The steps to accomplish this are as follows:2ln(x) = ln(4) + ln(16)ln(x^2) = ln(4*16)ln(x^2) = ln(64)By taking the exponential of both sides, this expression can be resolved.x^2 = 64x = ±8Since the natural logarithm is only defined for positive numbers, only the positive value of x is taken into account. Therefore, the solution is x = 8.The process of checking for extraneous solutions involves substituting the answer obtained into the original equation and evaluating it to see whether it is accurate or not.2ln(8) = ln(4) + ln(16)The above equation can be simplified to become: ln(64) = ln(64)The answer is consistent. As a result, the solution is accurate and does not include any extraneous values. The solution is x = 8.

The null and alternative hypotheses are \(H_o\) μ= 64.2 and \(H_a\): μ ≠ 64.2 respectively.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.
The average height of an 18-year-old American woman is 64.2 inches
Hypotheses state claims about a population parameter.
p: population proportion: population mean
σ: population standard deviation
The null hypothesis asserts that the sample size equals the claim value:
\(H_o\) :μ= 64.2
The alternate hypothesis expresses the inverse of the null hypothesis (As per the claim):
\(H_a\) : μ ≠ 64.2
μ = The average height of 18-year-old American women in the population.
\(H_o\) :μ= 64.2
\(H_a\) : μ ≠ 64.2
Thus, the null and alternative hypotheses are \(H_o\) μ= 64.2 and \(H_a\): μ ≠ 64.2 respectively.

Answer:
Option A
Step-by-step explanation:
\( \frac{12}{25} \times \frac{11}{24} \times \frac{10}{23} \times \frac{9}{22} \)
we start with 12 red marbles out of 25 marbles, that's the probability for the first.
in the second step we have one red marble less, wich also means one marble less overall
and so on
\( \frac{12 \times 11 \times 10 \times 9}{25 \times 24 \times 23 \times 22} \)
