Itried to figure it out but i can't. i need to show the work and i don't know how to do it.

Integration Formula:

Integrate each term:

Altogether this becomes:

Your limits are 1 and 2. Substitute both numbers into the equation and minus them from each other.

x = 2:

-

x = 1:

" alt="\frac{\frac{1}{3} - \frac{1}{2}-5 }{ \frac{1}{2}+2}" />" />

x = 2:

-

x = 1:

=

-1.212317928

Now convert all the answers to integers and see which one matches -1.212317928:

Because it's a negative number, we know it can only be A or B.

(A) = -1.212317928

(B) = -1.19047619

The answer is A:

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
