Answer:

Following are the answer to this question:

Step-by-step explanation:

Matrix:

$A=\left[\begin{array}{cc}0.3&0.7\\1&0\end{array}\right]$

$A^2=\left[\begin{array}{cc}0.79&0.21\\0.3&0.7\end{array}\right]$

In the above-given matrix, all entries of the matrix A² will be positive and the matrix A will be the transition of the matrix A, that regulates the Markov chain.

In the diagram below, the circle has a radius of 25 inches. the area of the unshaded is 500pi in^2Determine and state the degree

Dmitriy789 [7]

$72^{\circ}$

1) In this question, we are going to make use of the formula for the area of that sector, to find the central angle.

2) So, let's write it out an expression involving the area of a circle, the unshaded area, and the shaded one and then plug into that the given data:

$\begin{gathered} A=\frac{\alpha}{360^{\circ}}\times\pi r^2 \\ A_{Unshaded}+A_{shaded}=A_{Circle} \\ 500\pi+\frac{\alpha}{360}\times\pi r^2=\pi r^2 \\ \\ 500\pi+\frac{α}{360}\pi25^2=25^2\pi \\ \\ 500\pi+\frac{125\piα}{72}=625\pi \\ \\ 500\pi +\frac{125\pi α}{72}-500\pi =625\pi -500\pi \\ \\ \frac{125\pi α}{72}=125\pi \\ \\ \frac{72\times \:125\pi α}{72}=72\times \:125\pi \\ \\ \frac{125\pi α}{125\pi }=\frac{9000\pi }{125\pi } \\ \\ α=72^{\circ} \\ \\ \end{gathered}$

Thus, the centra angle of that shaded area is 72º

10<br> TIME REMAINING<br> 50:51<br> What are the solutions of x squared + 6 x minus 6 = 10?

aleksandrvk [35]

Answer:

X = -8 and X = 2

Step-by-step explanation:

X^2 + 6X - 6 = 10

Bring the 10 over:

X^2 + 6x - 16 = 0

From here, either use the quadratic formula or

manual factorization by finding its roots:

Manually:

(X + 8)(X - 2) = 0

Equate each factor to 0 you will get:

X + 8 = 0 and X - 2 = 0

Solutions are -8 and 2 respectively.
