Step-by-step explanation:
I'm trying to solve this problem but there's something wrong
What's the radius of one ball?
18 divided by 30 is 0.6. So I would say that B, or 0.6, is the correct answer.
Answer: A
Step-by-step explanation:
To find the inner product of two vectors (a,b) and (c,d) you would use the equation (a * c) + (b * d)
So for (7,2) and (0,-2) the inner product would be
(7 * 0) + (2 * -2)
= 4
The vectors are only perpendicular when the inner product is equal to 0. Since it is equal to -4 in this case, the vectors are not perpendicular.
A -4; no
I think acute but I’m really not sure
An improper fraction is when the numerator is greater. For example, 1 7/8 = 15/8
