Answer:
The degree of this polynomial is "8"
Step-by-step explanation:
Recall that the degree of a polynomial is given by the degree of its leading term. Recall as well that the degree of a term is the maximum number of variables that appear in it.
So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.
1) term
contains one variable "m" and four variables "n", so a total of five. Then its degree is: 5
2) term
contains one variable "m", two variables "n", and five variables "p". that is a total of eight variables. Then its degree is: 8
3) term
contains one variable n and one variable p. That is a total of 2. Then its degree is 2.
Based on the analysis above, and the fact that the term with highest degree is that of degree 8, the polynomial has degree 8.
Answer:
9/14
Step-by-step explanation:
81/126=9x9/9x14=9/14
The direction of a vector is the orientation of the vector, that is, the angle it makes with the x-axis.
The magnitude of a vector is its length.
The formulas to find the magnitude and direction of a vector are:
![\begin{gathered} u=❬x,y❭\Rightarrow\text{ Vector} \\ \mleft\Vert u|\mright|=\sqrt[]{x^2+y^2}\Rightarrow\text{ Magnitude} \\ \theta=\tan ^{-1}(\frac{y}{x})\Rightarrow\text{ Direction} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20u%3D%E2%9D%ACx%2Cy%E2%9D%AD%5CRightarrow%5Ctext%7B%20Vector%7D%20%5C%5C%20%5Cmleft%5CVert%20u%7C%5Cmright%7C%3D%5Csqrt%5B%5D%7Bx%5E2%2By%5E2%7D%5CRightarrow%5Ctext%7B%20Magnitude%7D%20%5C%5C%20%5Ctheta%3D%5Ctan%20%5E%7B-1%7D%28%5Cfrac%7By%7D%7Bx%7D%29%5CRightarrow%5Ctext%7B%20Direction%7D%20%5Cend%7Bgathered%7D)
In this case, we have:
• Magnitude
![\begin{gathered} w=❬-10,-12❭ \\ \Vert w||=\sqrt[]{(-10)^2+(-12)^2} \\ \Vert w||=\sqrt[]{100+144} \\ \Vert w||=\sqrt[]{244} \\ \Vert w||\approx15.620\Rightarrow\text{ The symbol }\approx\text{ is read 'approximately'} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20w%3D%E2%9D%AC-10%2C-12%E2%9D%AD%20%5C%5C%20%5CVert%20w%7C%7C%3D%5Csqrt%5B%5D%7B%28-10%29%5E2%2B%28-12%29%5E2%7D%20%5C%5C%20%5CVert%20w%7C%7C%3D%5Csqrt%5B%5D%7B100%2B144%7D%20%5C%5C%20%5CVert%20w%7C%7C%3D%5Csqrt%5B%5D%7B244%7D%20%5C%5C%20%5CVert%20w%7C%7C%5Capprox15.620%5CRightarrow%5Ctext%7B%20The%20symbol%20%7D%5Capprox%5Ctext%7B%20is%20read%20%27approximately%27%7D%20%5Cend%7Bgathered%7D)
• Direction

Therefore, the magnitude and direction of the vector are:
