Answer:
B
Step-by-step explanation:
120 degrees is 1/3 of the circumference of a circle.
So the formula is 2 * pi * r * theta / 360
Arc length = 2* 12 * 3.14 * 120/360
Arc length =25.12 feet
The x value is 1 because it is in between 4 and -2.
It is 3 away from 4 and 3 away from -2.
Hope this helps!
It's a 2nd degree algebraic expression in ' y '.
It's pretty messy in this form, and it can be substantially cleaned up.
Looking at just the second term, we can remove the parentheses:
3 (4y² - 2) = 12y² - 6
Now we can put that into the original expression ... 3y² + 12y² - 6
then combine the y² terms: <em>15y² - 6</em> .
If you want to go one step farther, we can factor it: <em>3(5y² - 2) </em>
