<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>

Answer:
Step-by-step explanation:
c=37
FIRST ONE: 2
2•10* *= 0 degrees
SECOND: 371
3.71 times 10 2s the two is at the top btw.
THIRD: 875
8.75 times 10 2s the two is also at the top.
LAST: 908
9.08 times 10 2s the two is at the top of 10.
Answer:
B
Step-by-step explanation:
B Rounded to nearest ten thousand
A is true. 50/20=2.5
b is true. 20 people come [every] three hours.
c is false. she isn't selling 1,600 if she has 100 berries left.
so C.
