To find Angle A we use cosine

cos ∅ = adjacent / hypotenuse

From the question

The adjacent is 17

The hypotenuse is 38

So we have

cos A = 17/38

A = cos-¹ 17/38

A = 63.4

A = 63° to the nearest degree

To find Angle C we use sine

sin ∅ = opposite / hypotenuse

From the question

The opposite is 17

The hypotenuse is 38

So we have

sin C = 17/38

C = sin-¹ 17/38

C = 26.57

C = 27° to the nearest degree

let be the -factorization of the matrix of rank . show how the least squares problem can be solved using the -factorization.

Answers

The -factorization of a matrix of rank provides a way to solve the least squares problem. By decomposing the matrix into the product of two matrices, the least squares solution can be obtained by solving a system of equations.

The -factorization, also known as the singular value decomposition (SVD), decomposes a matrix into the product of three matrices:

A = UΣV^T, where U and V are orthogonal matrices, and Σ is a diagonal matrix with singular values.

For a matrix of rank , the diagonal matrix Σ will have non-zero singular values only in the first columns.

To solve the least squares problem, we consider the linear system

A*x = b, where A is the matrix, x is the unknown vector, and b is the target vector. Using the -factorization, we can rewrite the system as

UΣV^T*x = b.

Since U and V are orthogonal matrices, they preserve vector norms. Multiplying both sides of the equation by U^T, we have ΣV^T*x = U^T*b.

Now, we can solve for x by performing the following steps:

1. Multiply U^T*b to obtain a new vector, say c.

2. Compute the inverse of Σ by taking the reciprocal of its non-zero singular values.

3. Multiply the resulting diagonal matrix with the vector c to get a new vector, say d.

4. Finally, multiply V with the vector d to obtain the least squares solution x.

By utilizing the -factorization, we have effectively transformed the least squares problem into a system of equations that can be solved using straightforward matrix operations.

Step-by-step explanation:

4/11 = 0.36363636(repeating)

If you consider a cube or a rectangular prism, you could identify it's volume through the multiplication of it's Base by height. A pyramid has 1 / 3rd that volume, so in order to take a volume of the figure to the left, we would multiply Base * height and take 1 / 3rd of that;

\(Square Pyramid,\\Base ( Square ) = a^2, a = length = 17.2 cm\\Height = 24.4 cm\\\\Volume = 1 / 3 ( Base ) ( Height ),\\Volume = 1 / 3 ( ( 17.2 )^2 )( 24.4 ),\\Volume = 1 / 3( 295.84 )( 24.4 ),\\\\Volume = 98.6133333333( 24.4 ),\\Volume = 2406.16533333,\\\\Volume = ( About ) 2406.165\)

Answers

The volume of the parallelepiped is 360 units cubed. Vector u, vector v, and vector w are all perpendicular (orthogonal).

A parallelepiped is a three-dimensional object with six faces. A parallelepiped is a prism-like object that is slanted or skewed. The face angles of a parallelepiped are all right angles, but its sides are not all equal.

The volume of a parallelepiped is determined by three vectors, namely, u, v, and w, and is represented by V(u,v,w) = |u * (v x w)| where "*" refers to the dot product and "x" refers to the cross product of the two vectors. Substituting the given vectors u, v, and w into the formula and calculating the volume of the parallelepiped gives 360 units cubed.A vector is considered perpendicular if it has a dot product of 0 with the other vector. The given vectors u, v, and w are perpendicular to each other. Thus, A.

The volume of a rectangular parallelepiped is equal to its surface area divided by its height. In this case, the surface area is the same as the rectangle's area divided by its length. As a result, the volume increases to; V is the length, width, and height. Therefore, we can determine the volume of the rectangular box if we know these three dimensions.

Solve the problem. Find parametric equations for the normal line to the surface
x^2 - 10xyz + y^2 = -8z^2 at the point (1, 1, 1).
a.x = -8t + 1, y = 8t + 1, z = 6t + 1
b.x = -8t + 1, y = -8t + 1, z = 6t + 1
c.x=t-8, y=t-8, z=t+6
d.x = t + 8, y = t + 8, z = t - 6

Answers

To find the parametric equations for the normal line to the surface x^2 - 10xyz + y^2 = -8z^2 at the point (1, 1, 1), we first need to find the gradient of the surface at that point. The gradient is a vector that is normal to the surface.

Taking partial derivatives of the equation with respect to x, y, and z, we have:

∂/∂x (x^2 - 10xyz + y^2) = 2x - 10yz

∂/∂y (x^2 - 10xyz + y^2) = -10xz + 2y

∂/∂z (x^2 - 10xyz + y^2) = -10xy - 16z

Evaluating these partial derivatives at the point (1, 1, 1), we get:

∂/∂x = 2(1) - 10(1)(1) = -8

∂/∂y = -10(1)(1) + 2(1) = -8

∂/∂z = -10(1)(1) - 16(1) = -26

Therefore, the gradient vector is (-8, -8, -26).

The parametric equations for the normal line passing through the point (1, 1, 1) are given by:

x = -8t + 1

y = -8t + 1

z = -26t + 1

Therefore, the correct answer is option b) x = -8t + 1, y = -8t + 1, z = -26t + 1.

Answers

The area of the rectangle ABCD is 56 Unit².

What exactly is a rectangle?

A rectangle is a two-dimensional geometric shape that is characterized by having four sides and four right angles. It is a type of quadrilateral.

The opposite sides of a rectangle are parallel and equal in length, and the adjacent sides are perpendicular to each other. This means that the opposite sides of a rectangle have the same distance apart throughout their entire length. The area of a rectangle is given by the formula A = lw, where l = length and w= width.

Now,

As √AEB=60°, and Side AE is equal to EB

and also angles opposite to equal sides are equal.

Then, ΔAEB is a equilateral triangle.

so, AB=8

Now

area of rectangle=length*breadth

Length=8 and breadth=BC=7

Area=8*7

A=56 unit²

Hence,

              The area of the given rectangle ABCD is 56 Unit².
