Let u = (1, 2 -2), v= (2, 1, 3) and w = j + 4k. a) Find cos theta, where theta is the angle in degrees between u and w.
1 answer:
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.

The scale of the copy of the ticket is 
Step-by-step explanation:
we know that
To find the scale divide the long of the copy of a ticket by the long of the original of a ticket
so

4r²<span>– 16 = 84
4r</span>² = 84+16
4r²= 100
r²=25
r=√25
r=<span>±5</span>
