A quadratic equation is shown:

insens350 [35]

Answer:

<em>The correct answer is the first option</em>

Step-by-step explanation:

<u>Quadratic Equation</u>

The standard form of a quadratic equation is

$ax^2+bx+c=0$

Sometimes we need to change the expression of the same equation to the form

$(x-p)^2=q$

To accomplish that change, we usually modify the left-hand expression to make it look like the square of a binomial.

The given quadratic equation is

$x^2-14x+41=0$

Recall the square of a binomial is

$(x-p)^2=x^2-2px+p^2$

The first term is already present. The second term gives us the value of p:

$-2px=-14x$

Solving

$p=7$

Now we need to produce the third term $p^2=49$ . We only have 41, thus we need to add 8 to both sides of the equation:

$x^2-14x+41+8=0+8$

The correct answer is the first option

Jonas made the following matrix of temperatures for the first 4 days of January.

valentinak56 [21]

Answer: The correct option is C.

Explanation:

It is given that Jonas made the following matrix of temperatures for the first 4 days of January and for the first 4 days of February.

Let the matrix A and B represents the temperatures for the first 4 days of January and February respectively.

$A=\begin{bmatrix}6 & -3 & 3 & -1\end{bmatrix}$

$B=\begin{bmatrix}1 & -3 & -5 & -6\end{bmatrix}$

The difference of January and February is defined by the matrix A-B.

To subtract two matrices, we subtract all the corresponding elements.

$A-B=\begin{bmatrix}6-1 & -3+3 & 3+5 & -1+6\end{bmatrix}$

$A-B=\begin{bmatrix}5 & 0 & 8 & 5\end{bmatrix}$

It is the option C.
