C. 5x+7=22 since diameter is equal to double the radius. radius=11 so diameter equals 22. then just make 5x+7 = to 22
Answer:
False
Step-by-step explanation:
the <u>dot product</u> between two vectors A and B is:
A·B=AB![cos\theta](https://tex.z-dn.net/?f=cos%5Ctheta)
where
is the angle between the vectors, if they are parallel, this angle is zero. so
and so the dot product is:
A·B =AB![cos(0)](https://tex.z-dn.net/?f=cos%280%29)
and since ![cos (0)=1](https://tex.z-dn.net/?f=cos%20%280%29%3D1)
the dot product is equal to
A·B=AB
The dot product of parallel vectors is NOT zero
Answer:
the ans is C..... good luck
