I think the answer might be B
Answer:
A) B is greater
B) when C = 21, A = 5 and B = 15
C) A must be 0, 5, or 12 for C to be greater than B
Step-by-step explanation:
A) when a = -3, c = -20 and b = 4(-3)-5 so B = -17
B) when c = 21, a = 5 and b = 4(5)-5 so B = 15
C) C is greater than B when a = 0, 5, and 12
when a = 0, b = 4(0)-5 or -5
when a = 5, b = 4(5)-5 or 15
when a = 12, b = 4(12)-5 or 43
Answer: The value of cos theta is -0.352.
Step-by-step explanation:
Since we have given that

We need to find the cos theta between u and w.
As we know the formula for angle between two vectors.

So, it becomes,

Hence, the value of cos theta is -0.352.
To solve this, all you need to do is multiply 16 by 3/8. When you multiply a whole number by a fraction, make the whole number into a fraction by putting it over 1.
16 3
---- x ---- Multiply the numerators together and then the denominators.
1 8
(16 x 3) / (1 x 8)
48 / 8 Then divide.
