Answer:
one
Step-by-step explanation:
for general form : ax²+bx+c=0
delta = b²-4ac
so for this example delta is 8²-4×2×8 =0
we know if delta = 0 , we have just one real number solution
so the answer is 1
He ran 100 meters in 9.63 seconds, so we can set up the equation below and do these steps...
100 meters = 9.63 seconds
10.384 meters = 1 second (divide both sides by 9.63)
37382.4 meters = 3600 seconds (multiply both sides by 3600)
37382.4 meters = 1 hour
His speed is roughly 37382.4 meters per hour, which is less than 40234 meters/hr = 25 mi/hr
<h3>Answer: his speed is less than the speed limit 25 mph</h3>
Firstly, This is what I think you know too. The numbers are always written like that (x,y). So, (1,9) and (4,9) , both of their y-axis are 9. Therefore, When a line is drawn, they intersect one another.
You could multiply 118.56 by .16 which is 19 dollars rounded and subtract 19 from 117.56 to get your answer
Power of 10. Times everything by 10. So example- 10x10 is 100
