What are the roots of this quartaic equation? -10x^2 + 12x - 9 = 0

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
