Answer:
Answers are (r,0) and (0,s)
Step-by-step explanation:
Given that in a rectangle ABCD, one vertex is the origin (0,0) A
The opposite vertex C is having coordinates as (r,s)
Since a rectangle has angle 90 we have x axis as one side and y axis as other side.
Length = r and width =s (since coordinates of C are (r,s))
Hence other coordinate B on x axis would be = (r,0)
and D on y axis = (0,s)
Answers are (r,0) and (0,s)
Answer:
3xz5+2x+4y−2z
Step-by-step explanation:
2x−5y+3z5x+9y−2z
=2x+−5y+3xz5+9y+−2z
Combine Like Terms:
=2x+−5y+3xz5+9y+−2z
=(3xz5)+(2x)+(−5y+9y)+(−2z)
=3xz5+2x+4y+−2z
By applying the definition of product between two <em>square</em> matrices, we find that ![\vec A \,\cdot \,\vec A = \left[\begin{array}{cc}1&2\\3&6\end{array}\right] \cdot \left[\begin{array}{cc}1&2\\3&6\end{array}\right]](https://tex.z-dn.net/?f=%5Cvec%20A%20%5C%2C%5Ccdot%20%5C%2C%5Cvec%20A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%262%5C%5C3%266%5Cend%7Barray%7D%5Cright%5D%20%5Ccdot%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%262%5C%5C3%266%5Cend%7Barray%7D%5Cright%5D)
is equal to the matrix ![\vec A \,\cdot \,\vec A = \left[\begin{array}{cc}7&14\\21&42\end{array}\right]](https://tex.z-dn.net/?f=%5Cvec%20A%20%5C%2C%5Ccdot%20%5C%2C%5Cvec%20A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D7%2614%5C%5C21%2642%5Cend%7Barray%7D%5Cright%5D)
