<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>

What is 5.8 × 106 mg/s in grams per minute?
Furkat [3]
1g=1000mg\to1mg=0.001g\\1min=60s\to1s=\frac{1}{60}min\\\\\\5.8\times10^6\ mg/s=5.8\times10^6\times\frac{0.001g}{\frac{1}{60}min}=5.8\times10^6\times0.001\times60\ g/min\\\\=5.8\times10^3\times60\ g/min=348\times10^3\ g/min=\boxed{3.48\times10^5\ g/min}

Which pair represents the same complex number?
lorasvet [3.4K]
For this case we have the following complex number:
 1 + i
 Its equivalent pair is given by:
 root (2) * (cos (pi / 4) + i * sin (pi / 4))
 Rewriting we have:
 root (2) * (root (2) / 2 + i * (root (2) / 2))
 (2/2 + i * (2/2))
 (1 + i)
 Answer:
 
option A represents a pair with the same complex number
