Can someone explain to me how do i do this?
this is for ap calculus

1. As , the expression will remain positive and veer off to positive infinity as well. The constant term and coefficient on don't affect this result:

In the opposite direction, means will be negative, so will also be negative. Then

2. As , the exponent will also go to positive infinity, so that

In the opposite direction, would veer off to negative infinity. Then

and as gets larger in magnitude, this would force the expression to converge to 0, so that

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
