Answer 1

Think about it graphically

If you're going to integrate from 10 to 10, does it cover an area?

Look at it this way, If I start at the 0 meter mark and I go to the 0 meter mark, did I cover any area?

Answer 2

no @FortyTheRapper

Answer 3

Correct, so the answer would be 0 in this case.
The other integrals they gave you were just extra info, so they tried to hit you up with a trick question xP

Answer 4

Thank you @FortyTheRapper Makes sense for a trick question. Can you help me with this?

Answer 5

Hmm, I may have a slight idea.

Let's first take the integral of this value. Would you know how to (Using the power rule)

Answer 6

yes

Answer 7

Wouldnt it get k^2(2k-5)

Answer 8

So you got k^2(2k-5)
At the beginning, they told you to equal that to k^2, so we should

k^2(2k-5) = k^2

Since they give answer choices, the best thing I think would be just to plug in that answer choice for k and see if they match
