A bee with velocity vector r ′ ( t ) starts out at the origin at t = 0 and flies around for T seconds. Where is the bee located at time T if ∫ T 0 r ′ ( u ) d u = 0 ? What does the quantity ∫ T 0 ∥ r ′ ( u ) ∥ d u represent?

At time T the bee will be at (0,0).

The quantity represents the integral of function with the time interval of (0,T).

Step-by-step explanation:

Given :

As we already know that

Thus we can say that

Now,          

So at time T the bee will be at (0,0).

if you was gonna solve for a, a is a   < -12

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
