Answer:
C. 6.3cm
Step-by-step explanation:
The length of the arc is calculated using the formula;
![l=\frac{Central\:angle}{360\degree} \times 2\pi r](https://tex.z-dn.net/?f=l%3D%5Cfrac%7BCentral%5C%3Aangle%7D%7B360%5Cdegree%7D%20%5Ctimes%202%5Cpi%20r)
The radius of the circle is r=10cm
The central angle is 36 degrees.
![l=\frac{36\degree}{360\degree} \times 2\times3.14\times10](https://tex.z-dn.net/?f=l%3D%5Cfrac%7B36%5Cdegree%7D%7B360%5Cdegree%7D%20%5Ctimes%202%5Ctimes3.14%5Ctimes10)
We simplify to get;
![l=\frac{1}{10} \times 3.14\times 20](https://tex.z-dn.net/?f=l%3D%5Cfrac%7B1%7D%7B10%7D%20%5Ctimes%203.14%5Ctimes%2020)
![l=3.14\times 2=6.3cm](https://tex.z-dn.net/?f=l%3D3.14%5Ctimes%202%3D6.3cm)
Answer:
x=-1.30068.......
Step-by-step explanation:
x( 3x^2 - 2) = -4
Distribute
3x^3 - 2x = -4
Add 4 to each side
3x^3 - 2x +4 = 0
Plot using a graphing calculator
x=-1.30068.......
Answer:
increase by 18
Step-by-step explanation:
put any number at c
f=32+1.8(5)
f=41
Then increase your number c by 10
f=32+1.8(15)
f=59
then figure out the difference
59-41=18
well logically i dont think you could simplify this problem since both of your variables arent like terms... you couldnt add them because of the squared 2c. im sorry i couldnt help you
