In 2010, 28,357 of the finishers were men, and 14,072 of the finishers were women. about how many men finished the race than women? to determine your aswer, did you round to the ten thousand or thousand? explain, me i am stuck

14,000.

Step-by-step explanation:

We have been given that in 2010, 28,357 of the finishers were men, and 14,072 of the finishers were women.

First of all, we will round both numbers. We can see that both numbers are ten-thousands. The thousands digit in 28,357 is greater, so it will round to 30,000.

The thousands digit in 14,072 is less than 5, so it will round down to 10,000.

The difference will be too far from the actual difference, so we will round both numbers to nearest thousands as:

Now, we will subtract number of women finishers from number of men finishers as:

Therefore, 14,000 more men finished the race than women.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
