Find a basis for the orthogonal complement of the subspace of R4 spanned by the vectors. v1 = (1, 4, -5, 3), v2 = (4, 15, 0, 5),
Arlecino [84]

Answer:

W1 =  ( -75, 20, 1 , 0 )

W2 = ( 25, -7 , 0, 1 )

Step-by-step explanation:

attached  below is the remaining part of the solution

for a homogenous system of equation ; Ax = 0

x1 + 4x2 -5x3 + 3x4 = 0

-x2 + 20x3 -7x4 = 0         note: x3 and x4 are free variables

we can take x3 = 0 and x4 = 1 , hence ; x2 = -7

∴ x1 - 28 + 3 = 0 = x1 = 25

W2 = ( x1 ,x2, x3, x4 ) = ( 25, -7 , 0, 1 )

now lets take x3 = 1  and x4 = 0   hence x2 = 20 , x1 = -75

∴ W1 =  ( x1 , x2 , x3, x4 ) = ( -75, 20, 1 , 0 )

Which function has two x intercepts one at (0,0) and one at (4,0)
marta [7]

Answer:

f(y) = y(y - 4).

Step-by-step explanation:

The function has two x-intercepts of the function are (0,0) and (4,0).

X-intercept means that the y-value will be zero.

Therefore, the function f(y) has two roots, one at y = 0 and another at y = 4.

Hence, the function x = f(y) has two factors (y - 0) and (y - 4)

So, the function is f(y) = (y - 0)(y - 4) = y(y - 4). (Answer)
