Answer:
1
Step-by-step explanation:
Use PEMDAS to solve the equation, and you will get the answer 1 for x
Answer:
Step-by-step explanation:
The missing details in the question are:
Required
The perimeter
This is calculated as:
So, we have:
Open bracket
Rewrite as:
First, rewrite the equation so that <em>y</em> is a function of <em>x</em> :
(If you were to plot the actual curve, you would have both and , but one curve is a reflection of the other, so the arc length for 1 ≤ <em>x</em> ≤ 8 would be the same on both curves. It doesn't matter which "half-curve" you choose to work with.)
The arc length is then given by the definite integral,
We have
Then in the integral,
Substitute
This transforms the integral to
and computing it is trivial:
We can simplify this further to
1. -10/9
2. 2/5
3. -2/5
4. 3/5
5. 1/10
6. -10/3
Answer: (-2/5,34/15) and (1/8,23/12).
