Step-by-step explanation:

Two vectors u and v whose dot product is u·v=0 are said to be orthogonal

u = <6, -2>, v = <2, 6>

u·v = u1*v1 + u2*v2

6*2 + -2 * 6

What is the value of m in the equation 1/2m-3/4n when n = 8?

kirill [66]

Answer:

$-\frac{1}{32}$

Step-by-step explanation:

$n = 8\\1/2(8) - 3/4(8) = 1/16-3/32$

Multiply the numerator and denomiator of 1/16 by 2 so that the denominators are equal and we can subtract.

$\frac{1}{16} *\frac{2}{2} =\frac{2}{32}$

Then, subtract

$\frac{2}{32} -\frac{3}{32} = \frac{2-3}{32} =- \frac{1}{32}$
