Answer:
-y^4+4y
Step-by-step explanation:
You can get a circle by cutting horizontally and a hyperbola by cutting vertically. You can also get an ellipse and a parabola by cutting at an angle depending on whether the cut comes out the other side or not.
<span>arc length = circumference • [central angle (degrees) ÷ 360]
Solving this equation for circumference:
</span>
<span>circumference = arc length / (central angle / 360)
</span><span>circumference = 12 / (85/360)
</span>circumference = 12 / <span><span>0.2361111111
</span>
</span>
<span>circumference =

"
Let
x--------> the number
we know that
the expressions is equal to
![4(x-7)=32](https://tex.z-dn.net/?f=%204%28x-7%29%3D32%20)
therefore
<u>the answer part 1) is</u>
![4(x-7)=32](https://tex.z-dn.net/?f=%204%28x-7%29%3D32%20)
<u>Part 2)</u> "One third of a number is
less than the number itself"
Let
x--------> the number
we know that
the expressions is equal to
![\frac{1}{3} x=(x-12 )](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20x%3D%28x-12%20%29%20%20)
therefore

![\frac{1}{3} x=(x-12 )](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20x%3D%28x-12%20%29%20%20)
<u>Part 3)</u> "Ten increased by the quotient of a number and
is

Let
x---------> the number
we know that
the expressions is equal to
![10+ (\frac{x}{2} )= -15](https://tex.z-dn.net/?f=%2010%2B%20%28%5Cfrac%7Bx%7D%7B2%7D%20%29%3D%20-15%20%20%20)
therefore
<u>the answer Part 3) is</u>
![10+ (\frac{x}{2} )= -15](https://tex.z-dn.net/?f=%2010%2B%20%28%5Cfrac%7Bx%7D%7B2%7D%20%29%3D%20-15%20%20%20)
<u>Part 4)</u> "One less than the product of a number and
is
more than the number itself"
Let
x---------> the number
we know that
the expressions is equal to
![(3x)-1=5+x](https://tex.z-dn.net/?f=%20%283x%29-1%3D5%2Bx%20)
therefore
<u>the answer Part 4) is</u>
![(3x)-1=5+x](https://tex.z-dn.net/?f=%20%283x%29-1%3D5%2Bx%20)
