The right answer for the question that is being asked and shown above is that: In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?

x2 - 6x + 9

So the answer on the blank space is 9. It should be a perfect square.
= 6/2
= 3^2
= 9

Determine whether the vectors u and v are parallel, orthogonal, or neither.
Komok [63]
<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal 
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them 

we know from above that u.v = 120 

|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29

so we know: 

theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>
