How many people are in the US? How many people died?

How many used-to-be presidents were there?

What is 1,165 to 5,000

about 300 million people and i didnt look it up i am just say 300 million because 3 is a good number and there are three types of rocks three types of clouds and three countrys in north america

im guessing infinite amount of people have died

45 used to be presidents duh because obama was the 44th president

and that last question is unanswerable

Step-by-step explanation:

also this is me 1087945

give me another one tomorrow

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

the answer is 15% decrease
