Answer:
Scalar product
Step-by-step explanation:
The scalar product of a matrix refers to the product of a matrix and a number. The scalar is used to multiply each element in the matrix to get the final vector. In the question the scalar is k which is a constant and the matrix is A.
in the example below 2 is the scalar
![2*\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]](https://tex.z-dn.net/?f=2%2A%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%262%263%5C%5C4%265%266%5C%5C7%268%269%5Cend%7Barray%7D%5Cright%5D)
the final matrix will be
![\left[\begin{array}{ccc}2&4&6\\8&10&12\\14&16&18\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%264%266%5C%5C8%2610%2612%5C%5C14%2616%2618%5Cend%7Barray%7D%5Cright%5D)
Answer:
Not sure but :
Y=15/7
X=13/5
Z=26/7
I will check them later and tell you if they are right or not .
Step-by-step explanation:
y power 2 : 31 × 8 = 248
Rad 248 = 15/7
x power 2 : 23 × 8 = 184
Rad 184 = 13/5
31 power 2 : (15/7) power 2 + z power 2
961 = 246/49 + z powe 2
z power 2 = 714/51
rad 714/51 = 26/7
z = 26/7
Answer:
No! The answer is not zero. There can be infinite solutions for this equation.
Hope it helps!
