Answer: Second Option

Step-by-step explanation:
We are evaluating aarco lengths
The formula for the arc length is:

We want to know what is the arc length for a radius of r = 8
Then we substitute r = 8 in the equation and solve


The correct answer is the second option
Such an expression is in its Simpliest Form
Answer:
x = 5/4 + √65/4 or x = 5/4 - √65/4
Step-by-step explanation:
I'm assuming you mean 2x^2-5x-5=0?
x = ( -b ± √b^2 - 4ac ) / 2a
x = ( -(-5) ± √(-5)^2 - 4(2)(-5) ) / 2(2)
x = ( 5 ± √(25 + 40) ) / 4
x = ( 5 ± √65 ) / 4
x = 5/4 ± √65/4
Therefore, x = 5/4 + √65/4 or x = 5/4 - √65/4
