Two vectors are orthogonal (perpendicular), if their dot-product is zero
they're parallel, if they're just the product of scalar multiplication

like say hmmm <3, 7>  and <12, 28>   well 4*3 is 12, and 4*7 is 28
thus <12, 28> is really 4<3,7>  so, those two are parallel

now.. let's check the dot-product on yours

<10, 0> • <0,-9>   will be (10*0) + (0*-9) = 0 + 0 = 0 <--- orthogonal

Dn80 pipe 88millimeters is According to the plan All openings must be 40mm larger than the pipe. You know that
N76 [4]

Answer:

128mm

Step-by-step explanation:

Given

Pipe = 88mm

Ope\ nnings = 40mm\ larger

Required

Determine the length of the openings of the pipe

To do this, we simply add 40mm to the length of the pipe.

This gives:

Ope\ nings = 88mm + 40mm

Ope\ nings = 128mm

<em>Hence, the opening must be 128mm</em>
