Answer:
15
Step-by-step explanation:
As you can see on the side it says 15 and that is the length of the structure and it would be the same all around
<u>ANSWER</u>

<u>EXPLANATION</u>
The Cartesian equation is

We substitute


and

This implies that

Let us evaluate the exponents to get:

Factor the RHS to get:

Divide through by r²

Apply the double angle identity

The polar equation then becomes:

We're given the Arithmetic Progression <em>-24, -4, 16, 36 ...</em> .
We know that a term in an AP is generally represented as:

where,
- a = the first term in the sequence
- n = the number of the term/number of terms
- d = difference between two terms
We need to find
.
From the given progression, we have:
- a = -24
- n = 23
- d = (-24 - (-4) = -20
Using these in the formula,

Therefore, the 23rd term in the AP is -464.

Yes, one pair of sides is both parallel and congruent
I think that's it
Okay so because it's 10% off you're going to take the original price ($25) and move the decimal over once. So, $2.50. Now back to the original price!
$25.00 - $2.50 = $23.50 for the sweatshirt. I don't think I explained that very well, but that'd be how you found your answer?
