It's Impossible.

Matrix can only be raised to a power if it has same number of rows and columns

Step-by-step explanation:

P= \begin{pmatrix}1&3&2\\ 3&2&1\end{pmatrix}\\\\P^2 = \begin{pmatrix}1&3&2\\ 3&2&1\end{pmatrix}^2\\\\\mathrm{Dimensions\:of\:matrix}\:\\\begin{pmatrix}1&3&2\\ 3&2&1\end{pmatrix}:\:2x3\\\mathrm{Matrix\:can\:only\:be\:raised\:to\:a\:power,\\\:if\:it\:has\:same\:number\:of\:rows\:and\:columns}

(problem 83)
AVprozaik [17]

To find the derivative of this function, there is a property that we should know called the Constant Multiple Rule, which says:

\dfrac{d}{dx}[cf(x)] = cf'(x) (where c is a constant)


Remember that the derivative of \csc(x) is -\csc(x)\cot(x). However, you may notice that we are finding the derivative of \dfrac{1}{2}\csc(2x), not \dfrac{1}{2} \csc(x). So, we are going to have to use the chain rule. To complete the chain rule for the derivative of a trigonometric function (in layman's terms) is basically the following: First, complete the derivative of the trig function as you would if what was inside the trig function is x. Then, take the derivative of what's inside of the trig function and multiply it by what you found in the first step.


Let's apply that to our problem. Right now, I am not going to worry about the \dfrac{1}{2} at the front of the equation, since we can just multiply it back in at the end of our problem. So, let's examine \csc(2x). We see that what's inside the trig function is 2x, which has a derivative of 2. Thus, let's first find the derivative of \csc(2x) as if 2x was just x and then multiply it by 2.


The derivative of \csc(2x) would first be -\cot(2x)\csc(2x). Multiplying it by 2, we get our derivative of -2\cot(2x)\csc(2x). However, don't forget to multiply it by the \dfrac{1}{2} that we removed near the beginning. This gives us our final derivative of -\cot(2x)\csc(2x).


Remember that we now have to find the derivative at the given point. To do this, simply "plug in" the point into the derivative using the x-coordinate. This is shown below:

-\cot[2(\dfrac{\pi}{4})]\csc[2(\dfrac{\pi}{4})]

-\cot(\dfrac{\pi}{2})\csc(\dfrac{\pi}{2})

-(0)(1) = \boxed{0}


Our final answer is 0.

If f (x) = startroot one-half x minus 10 endroot 3, which inequality can be used to find the domain of f(x)? startroot one-half
tankabanditka [31]

A function assigns values. The inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The domain of a function is a set of values for which the equation is satisfied. Since the function has under root values, the value which is under the root should be non-negative so that it does not give a complex number,  therefore,

The inequality \sqrt{\dfrac12x^2-10}\geq 0satisfied to find the domain of the function f(x).

Also, we can write that 0.5x²-10≥0 for the value to be positive.

Hence, the inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.
