Answer:
g(x)
Step-by-step explanation:
The vertex of g(x) as shwon in the graph is located in the point wich coordinates are (3.5,6.25) approximatively
We need to khow the coordinates of f(x) vertex
- Here is a way without derivating:
f(x) = -x² + 4x -5
let a be the leading factor, b the factor of x and c the constant:
The coordinates of a vertex are: (
, f(
) )
-b/2a = -4/ (-1*2) = 4/2 = 2
f(2)= -2²+4*2-4 = -4+4-4 = -4
obviosly f(x) has a minimum wich less than g(x)'s maximum
Answer:
15 people will be served before the cooler would be empty
Step-by-step explanation:
Here, we want to know the number of persons that could be served if the total amount of water available is 7.5L and each serving is 500 milliliters
What we are going to do here is to divide the total amount of water available by the number of individual servings
Mathematically, that would be;
7.5L / 500 milliliters
So we need to convert 7.5L to milliliters
Since 1000 mL = 1L ; 7.5 L = 7.5 * 1000 = 7500 mL
So the number of people served will be;
7500/500 = 15 people
