Determine whether the vectors u and v are parallel, orthogonal, or neither. u = <10, 0>, <0, -9> (5 points)
1) Parallel
2) Orthogonal
3) Neither

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.

Where are the

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
