Empire elementry school needs to purchase water bottles for field day. there are 2,142 students. principal vadar rounded to the nearest hundred to estimate how many water bottles to order. will there be enough water bottles for everyone? explain.

2,100 would be the nearest hundred

Step-by-step explanation:

If a number is 1-4 you round down if a number is 5 it stays the same and if a number is 6-9 you round up

in this case there is a 4 in the tens place so you will round down

15.5

step-by-step explanation:

5

∑

n = 1

substitute n = 1, 2, 3, 4, 5 and sum the terms

= + + + 2² + 2³

= 0.5 + 1 + 2 + 4 + 8

= 15.5

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
