Answer:
$1917.60
Step-by-step explanation:
Interest = Principal x Rate x Time
103.55 = (.05)(13/12)P
103.55 = .054P
P = 1917.60
I think its 20 but I'm not sure
B & c
they both go up while a goes down
Answer:

Step-by-step explanation:
We are given the integral of:

First, we can use a property to separate a constant out of integrand:

Next, expand the expression (integrand):

Since
then it can be simplified to:

Recall the formula:

For
, we need to convert to another identity since the integrand does not have a default or specific integration formula. We know that:

We can solve for
which is:

Therefore, we can write new integral as:

Evaluate each integral, applying the integration formula:

Then add all these boxed integrated together then we'll get:

Expand 4 in the expression:

Therefore, the answer is:
