Answer:
how many numbers have absolute value 3? zero is your answer
how many numbers have absolute value a, if a>0? your answer is also zero
Step-by-step explanation:
Ie 32^2 - 4ac=0 so ac=256 and a+c=130
So, that means:2 equations ac=256 a+c=130 ie c=130-a
So,a(130-a)=256 so 130a -a^2=256 ie a^2-130a +256=0 (a-2)(a-128)=0
Finally,giving a= 2 or a=128 so, a=2 c=128 or a=128 c=2
Since, a>c , a=128 and c=2 ie (128,2)
milli = 1/1000, so milligams = 1/1000 of a gram.
So:
2000 milligrams * 1 gram/1000 milligrams = 2 grams.
