tester [92]

Answer:

(1/17) [In |eˣ - 4| - 0.5 In |e²ˣ + 1| - 4 arctan eˣ] + c

Step-by-step explanation:

The solution to the question is provided in the attached image.

The right substitution is y = eˣ

y = eˣ

(dy/dx) = eˣ

dy = eˣ dx

dx = (dy/eˣ)

And x = In y

We then obtain an expression that can be resolved into integrable form by resolving into partial fractions.

After this, the partial fractions is then integrated; giving the final answer obtained.

A 324 ​-inch pipe is cut into two pieces. One piece is five times the length of the other. Find the length of the shorter piece.
miv72 [106K]

Answer:

64.8 in

Step-by-step explanation:

The pipe is 324 in and you cut in in two. Since we know that one piece is five times the length of the other, we can make the equation  324=5x. Divide both sides by five gets us 64.8 = x.

To check our work, let's multiply 64.8 by 5. It does equal 324 so we are correct.
