Solve Picture Below (its pretty ez)

The solution to the homogenous equation is M = c₁e⁻(ⁿ² + √[n(n+1)n] + c₂e⁻(ⁿ²-√[n(n+1)n

To solve the second order differential equation:

d²M/dn² + 2n (dM/dn) = n

We can use the method of undetermined coefficients. First, we assume a particular solution of the form M = An + B, where A and B are constants to be determined. We then find the first and second derivatives of M:

dM/dn = A

d²M/dn² = 0

Substituting these into the differential equation, we get:

0 + 2n(A) = n

Solving for A, we find:

A = 1/2

So the particular solution is:

M = (1/2)n + B

To find B, we can substitute the particular solution into the original differential equation:

d²M/dn² + 2n (dM/dn) = n

0 + 2n(1/2) = n

So the homogeneous solution is:

Mh = C1n + C2

where C1 and C2 are constants to be determined. The general solution is the sum of the homogeneous and particular solutions:

The solution to the homogenous equation is;

M = c₁e⁻(ⁿ² + √[n(n+1)n] + c₂e⁻(ⁿ²-√[n(n+1)n

Answer:

$57.14

Step-by-step explanation:

Option B. 5 and one-third units. The value of a in triangle XYZ is 5 and two-thirds units. This is found using the Pythagorean theorem twice and solving for a.

To find the value of a, we can use the Pythagorean theorem in triangles WZY and WYX as follows:

In triangle WZY:

[tex]c^2 = 3^2 + (a + 4)^2[/tex]

In triangle WYX:

[tex]b^2 = 4^2 + a^2[/tex]

Since angle ZWX is a right angle, we can use the Pythagorean theorem in triangle ZWX as follows:

[tex]ZWX^2 = ZW^2 + WX^2[/tex]

We know that ZW = c and WX = b, so we have:

[tex]a^2 + b^2 = c^2[/tex]

Substituting[tex]c^2[/tex] in terms of a and simplifying, we get:

[tex]a^2 + b^2 = 25 + (a + 4)^2[/tex]

Expanding and simplifying, we get:

[tex]a^2 + b^2 = a^2 + 8a + 41[/tex]

Subtracting [tex]a^2[/tex] from both sides, we get:

[tex]b^2 = 8a + 41[/tex]

Substituting [tex]b^2[/tex] in terms of a in the equation [tex]a^2 + b^2 = c^2[/tex], we get:

[tex]a^2 + 8a + 41 = c^2[/tex]

Substituting[tex]c^2[/tex] in terms of a from the equation for triangle WZY, we get:

[tex]a^2 + 8a + 41 = 9 + (a + 4)^2/16[/tex]

Expanding and simplifying, we get:

[tex]16a^2 + 128a + 656 = 9a^2 + 50a + 97[/tex]

Simplifying further, we get:

[tex]7a^2 + 78a - 559 = 0[/tex]

Using the quadratic formula, we get:

[tex]a = (-78 ± sqrt(78^2 + 4(7)(559))) / 14[/tex]

a = (-78 ± sqrt(49379)) / 14

Since a represents a length in a triangle, it must be positive. Therefore, we have:

a = (sqrt(49379) - 78) / 14 ≈ 6.67

The answers to the given numerical expressions are:

(12-5)^2 + (-18) x 4 = 49 + (-72) = -23

4^3 + (15-3) ÷ 2 = 64 + 6 = 70

The point (2,3) and  (2,-5) both lie on the circle with center (-1,-1) and radius 5.

In geometry, a circle is a closed shape consisting of all points in a plane that are a fixed distance (called the radius) from a given point (called the center). The circle is one of the most basic geometric shapes, and it has many important properties.

In this case, we have a circle with center (-1,-1) and radius 5, so its equation is:

(x + 1)² + (y + 1)² = 5²

We also know that the point (2,b) lies on this circle, so we can substitute x = 2 and y = b into the equation to get:

(2 + 1)² + (b + 1)² = 5²

9 + (b + 1)² = 25

Subtracting 9 from both sides, we get:

(b + 1)² = 16

b + 1 = ±4

Solving for b in each case, we get:

b = -1 ± 4

Therefore, the possible values of b are:

b = 3 or b = -5

So the point (2,3) and the point (2,-5) both lie on the circle with center (-1,-1) and radius 5.

The Lagrangian form of the interpolating polynomial p2(x) corresponding to the data in the table is,

p2(x) = L0(x) × y0 + L1(x) ×y1 + L2(x) ×y2

where Li(x) for i = 0,1,2 are the Lagrange basis polynomials defined by,

L1(x) = (x - x0) × (x - x2) / (x1 - x0) × (x1 - x2)

L2(x) = (x - x0) × (x - x1) / (x2 - x0) × (x2 - x1)

a) The scale of the drawing is 1 in. 3 ft.

b) the scale of the new​ drawing is 1 inch = 4 feet.

What is proportion?

The size, number, or amount of one thing or group as compared to the size, number, or amount of another. the proportion of boys to girls in our class is three to one.

Part 1: The scale of the drawing is 1 in. 3 ft.

Part 2: To find the scale of the new​ drawing, we can set up a proportion using the scale of the original drawing:

1 inch : 3 feet = x inches : 1 foot

Simplifying this proportion, we get:

1/3 = x/12

Multiplying both sides by 12, we get:

x = 4

So the scale of the new​ drawing is 1 inch = 4 feet.

In the new scale​ drawing, a length of 4 inches represents an actual length of 16 feet (since 1 inch represents 4 feet).

Hence, a) The scale of the drawing is 1 in. 3 ft.

A word problem in mathematics simply refers to a question that is written as a sentence or in some cases more than one sentence which requires an individual to use his or her mathematics knowledge to solve the real life scenario given.

It should be noted that to find the number of hand-held color televisions sold at $320 per television, we need to substitute p = 320 into the supply model or demand model and solve for N.

Using the supply model:

N = 2.4p = 2.4(320) = 768

Answer:

Yes, I can help you simplify that expression.

Starting with the expression:

p(p-2) x (2/p)

You can simplify it by first multiplying the terms in the first set of parentheses:

p(p-2) = p^2 - 2p

Then you can rewrite the second term as a fraction with a common denominator of p:

2/p = 2p/p^2 = 2/p^2

Now the expression becomes:

(p^2 - 2p) x (2/p^2)

Next, you can factor out a 2 from the first set of parentheses:

2p(p - 1) x (2/p^2)

Finally, you can simplify the expression by canceling out the p in the second fraction:

2(p - 1)

So the simplified expression is 2(p - 1).

The piecewise function for f(x) is f(x) = x - 2, x ≥ 2; -x + 2, x < 2, So the correct answer is option C.

In mathematics, a function is a rule that assigns each element of a set (called the domain) to a unique element of another set (called the range). Functions are a fundamental concept in mathematics and are used to describe relationships between variables, as well as to model and solve a wide range of mathematical problems.

A function is typically denoted using a letter such as "f", and is defined by an equation or formula that specifies how the input (or domain) values are transformed into output (or range) values. For example, the function "f(x) = 2x + 1" assigns each input value "x" to an output value equal to twice the input value plus one.

The absolute value function f(x) = |x - 2| can be written as a piecewise function by separating it into two cases:

Case 1: x - 2 ≥ 0 or x ≥ 2

In this case, the expression inside the absolute value bars becomes x - 2, so f(x) = x - 2.

Case 2: x - 2 < 0 or x < 2

In this case, the expression inside the absolute value bars becomes -(x - 2) = -x + 2, so f(x) = -x + 2.

Therefore, the piecewise function for f(x) is:

f(x) =

x - 2, x ≥ 2

-x + 2, x < 2

So the correct answer is option C.

Select the true statement.

the solution to the equation -4(y - 2) = 12 is y = -1.

How to solve?

(1.) -3x - 5 = 16

To solve for x, we need to isolate the variable on one side of the equation. We can start by adding 5 to both sides:

-3x - 5 + 5 = 16 + 5

-3x = 21

Next, we can divide both sides by -3 to get the value of x:

x = -7

Therefore, the solution to the equation -3x - 5 = 16 is x = -7.

(2.) -4(y - 2) = 12

To solve for y, we can start by simplifying the left side of the equation by distributing the -4:

-4y + 8 = 12

Next, we can isolate y by subtracting 8 from both sides:

-4y + 8 - 8 = 12 - 8

-4y = 4

Finally, we can solve for y by dividing both sides by -4:

y = -1

Therefore, the solution to the equation -4(y - 2) = 12 is y = -1.

After answering the provided question, we can state that Therefore, the parallelograms measure of angle C is 63°.

In Euclidean geometry, a parallelogram is a simple quadrilateral with two sets of parallel sides. A parallelogram is a type of quadrilateral in which both sets of opposite sides are parallel and equal. Parallelograms are classified into four types, three of which are unique. The four different shapes are parallelograms, squares, rectangles, and rhombuses. A quadrilateral is a parallelogram when it has two sets of parallel sides. The opposing sides and angles of a parallelogram are both the same length. The interior angles on the same side of the horizontal line are also angles. 360 degrees is the total number of interior angles.

Since ABCD is a parallelogram, opposite angles are congruent. Therefore,

m∠A = m∠C

13x - 41 = 6x + 15

x = 8

m∠C = 6(8) + 15 = 63
