5% p.a will rate of interest
Answer:
y=4, x=8
Step-by-step explanation:
system:
x+y = 12, x=2y
convert to 1 variable, simplify:
2y+y=12
3y=12
y=4
x=2y=4*2=8

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.
