Give an example of a 2x2 matrix without any real eigenvalues:___________
9966 [12]

Answer:

Step-by-step explanation:

An eigenvalue of n × n is a function of a scalar \lambda  considering that there is a solution (i.e. nontrivial) to an eigenvector x of Ax =  

Suppose the matrix A = \left[\begin{array}{cc}-1&-1\\2&1\\ \end{array}\right]

Thus, the equation of the determinant (A - \lambda1) = 0

This implies that:

\left[\begin{array}{cc}-1-\lambda &-1\\2&1- \lambda\\ \end{array}\right] =0

-(1 - \lambda^2 ) + 2 = 0

-1 + \lambda ^2 + 2= 0

\lambda^2 +1 =0

Hence, the eigenvalues of the equation are \mathtt{\lambda = i , -i}

Also, the eigenvalues can be said to be complex numbers.

Andy has a stamp collection with 343 stamps, Of these 296 are from Germany. Is 40,50 or 60 a more reasonable estimate for how ma
mariarad [96]

Answer:

40 Stamps

Step-by-step explanation:

According to the scenario, given data are as follows,

Total stamp collected = 343

Stamps from Germany = 296

To estimate the stamps from other contact, we first round off the given number of stamps.

So, Total stamp collected = 340 ( Rounded off)

Stamps from Germany = 300 ( Rounded off)

So, Stamps from other contact = 340 - 300 = 40 stamps

Cubic bins with closed tops are used to transport melons to the farmers market. The edge length of each bin is 1. 5 m. What is t
Contact [7]

Cube has all six faces as square. The surface area of the outside of one of the bins is 13.5 m².

<h3>What is the surface area of the cube?</h3>

The surface area of the cube is the sum of the area of all the sides of the cube. All the six sides of the cube are made of the same size square, therefore, the surface area of the cube is 6s², where s is the length of its single side.

As it is given that the melons are kept in cubic bins whose top is closed, therefore, the cubic bin will have all six sides, with the length of the side as 1.5m.

We know the formula for the surface area of the cube, therefore, the surface area of the cubic bin is equal to the surface area of the cube with side 1.5m,

\text{Surface area of the cube} = 6s^2

                                     = 6(1.5)^2\\\\= 6 \times 2.25\\\\=13.5\rm\ m^2

Hence, the surface area of the outside of one of the bins is 13.5 m².
