7 0

Answer:

symmetric matrix is the square matrix and it is equal to its transpose

Step-by-step explanation:

solution

a symmetric matrix is the square matrix and it is equal to its transpose

As A is symmetric matrix  then

A = A^{T}

here only square matrices will be symmetric

and matrix A is symmetric its mean its matrices have equal dimension

and every square diagonal matrix is also symmetric when all off diagonals element is zero

symmetric matrix for all indices i and j

A = aij = aji

Solve for the variable r
Sonja [21]

Answer:

see explanation

Step-by-step explanation:

Given

V = πr²h ( isolate r² by dividing both sides by πh )

\frac{V}{h\pi } = r² ( take the square root of both sides )

\sqrt{\frac{V}{h\pi } } = r

The inverse of Fx) is a function.<br> FOD<br> A. True<br> B. False
anastassius [24]
Not all functions have inverse functions. Those that do are called invertible. For a function f: X → Y to have an inverse, it must have the property that for every y in Y, there is exactly one x in X such that f(x) = y.

3. Sоlvе з+2У-1 and x-2y = 13. (D)<br>ху<br>ху​
sp2606 [1]

Answer:

The value of x and y for the given two linear equation is x = 7 , y = - 3

Step-by-step explanation:

Given two linear equation as :

x + 2 y - 1 = 0            

Or, x + 2 y = 1               ..........A

x - 2 y = 13                    ............B

Now, Solving both equations A and B

i.e (x + 2 y) + (x - 2 y) = 1 + 13

Or, (x + x) + (2 y - 2 y) = 14

Or, 2 x + 0 = 14

Or, 2 x = 14

∴ x = \dfrac{14}{2}

i.e x = 7

Now, Put the value of x into eq A

So, 7 + 2 y = 1

Or, 2 y = 1 - 7

Or, 2 y = - 6

∴  y = \dfrac{- 6}{2}

i.e y = - 3

So, The value s of x = 7 and y = - 3

Hence, The value of x and y for the given two linear equation is x = 7 ,          y = - 3 Answer
