Sorry I'm not sure how to solve this one but maybe you have to multiply
The curve

is parameterized by

so in the line integral, we have





You are mistaken in thinking that the gradient theorem applies here. Recall that for a scalar function

, we have gradient

. The theorem itself then says that the line integral of

along a curve

parameterized by

, where

, is given by

Specifically, in order for this theorem to even be considered in the first place, we would need to be integrating with respect to a vector field.
But this isn't the case: we're integrating

, a scalar function.
Answer: There are no like terms.
Answer:=−x^2+2x+7
Step-by-step explanation: Hope this help :D
The tip amount is $2.23
Because...
14.85 x .15 = 2.2275
Rounding gets you your answer . Good luck (:
