Answer:
60
Step-by-step explanation:
You have to multiply the top and bottom of the fraction (2/5) by 30 so the denominator will be 150. You also have to multiply the top by 30 (2 times 30). The answer is 60 will be rainbow colored!
2 x 30 = 60
5 x 30 = 150
<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>
