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.

Answer:

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 fastest speed at which you can go around the curve without the book sliding is equal to 4.43 m/s.

According to Newton's Second law of motion, the centrifugal force which acts on a physical object that is moving around a curve in the x-direction (x-coordinate) and y-direction (y-coordinate) is modeled by the following mathematical equations:

∑Fx = Fc = mv²/r (x-direction)

∑Fy = Fmax = n - W = mg = 0

Fmax = μmg

Where:

Generally speaking, the maximum speed of a physical object would be attained when its static friction is maximum. Therefore, we would have the following:

Fmax = μmg = mV²/r

Making V the subject of formula, we have:

Maximum speed, V = √μgr

Maximum speed, V = √(0.2 × 9.8 × 10)

The required Lagrangian form of the polynomial p2(x) is given by

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,

L0(x) = (x - x1) × (x - x2) / (x0 - x1) × (x0 - x2)

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

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

Substituting the values of xi and yi from the table, we get,

p2(x)

Write the Lagrangian form of the interpolating polynomial p2 corresponding to the data in the table below

x0   y0

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).

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

M = 1/8t - 223.05

Step-by-step explanation:

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:

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

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

7x = 56

x = 8

m∠C = 6(8) + 15 = 63

An aging of accounts receivable is a report that categorizes a company's accounts receivable by the length of time the invoices have been outstanding. The report typically breaks down the receivables by 30-day periods, such as 0-30 days, 31-60 days, 61-90 days, and 91+ days. This report is used to help management identify which accounts are overdue and may require follow-up action, and to estimate the amount of bad debt expense that may need to be recorded.

Selling on account has several advantages, such as increasing sales revenue and customer loyalty. It also allows customers to buy products or services they need without having to pay immediately, which can be beneficial for both parties. However, there are also disadvantages, such as the risk of non-payment, the need to manage accounts receivable and collection efforts, and the potential for bad debt expense. Additionally, selling on account may require additional resources to manage, such as billing and collections staff.

Notes Receivable is a written promise to pay a specified amount of money at a specific future date. Accounts Receivable, on the other hand, represent amounts owed to a company by its customers for goods or services sold on credit. Notes Receivable usually carry interest and have a longer-term repayment schedule compared to Accounts Receivable, which are typically due within a shorter time frame, such as 30 days.
