Step-by-step explanation:
12.5% is for a hour, so if Maxine did 3 hours more than that would be (12.5x 3 ) 37.5%
$50 per day.
First you divide 250 dollars by 5 then you will get 50 dollars
Answer:

Step-by-step explanation:
So we have the integral:

First, let's use substitution to get rid of the x/2. I'm going to use the variable y. So, let y be x/2. Thus:

Therefore, the integral is:

Now, as you had done, let's expand the tangent term. However, let's do it to the fourth. Thus:

Now, we can use a variation of the trigonometric identity:

So:

Substitute this into the integral. Note that tan^4(x) is the same as (tan^2(x))^2. Thus:

Now, we can use substitution. We will use it for sec(x). Recall what the derivative of secant is. Thus:

Substitute:

Expand the binomial:

Spilt the integral:

Factor out the constant multiple:

Reverse Power Rule:

Simplify:

Distribute the 2:

Substitute back secant for u:

And substitute back 1/2x for y. Therefore:

And, finally, C:

And we're done!
