The central angle COA = 2 * angle at the circumference
m < COA = 2 * 80 degrees
Answer:
508,364
Step-by-step explanation:
just add them together :)
Ok so factoring quadratics is fairly easy once you get the hang of it
So we have a quadratic 
My first question would be what 2 numbers multiply to -2 and add to +1
the answer is 2 and -1
Second question what 2 values multiply to get 
the answer x and x
your factored form would be 
This is as far as i can explain there is a whole lot about quadratics to be learned. You have to ask your teacher on more information
The answer is 140 because you have to divid lol idek I don’t speak espaniol
Answer: 14.48000 . . . ≤ t < 15.0000
Step-by-step explanation:
"Truncated by a hundreths of a second" means that the time was rounded to the nearest 0.0X second. That would mean the reported time of 14.48 seconds was shortened from a time period having more digits to the right. For example, If the time were actually 14.48223 seconds, the time was truncated to just 14.48 seconds. The term used here. truncated, means that the digits after the hunredth place are simply dropped. It doesn't say rounded, just truncated. Brutal. So that would mean that times between 14.48000 . . . and 14.48999 . . . would all be reported as 14.48 seconds.
So the time could actually be 14.48000 . . . ≤ t < 15.0000
