Given ,
Concentrate= 250 mL
Water = 1 liter = 1000 mL
A) ratio is 250:1000 = 1:4
B) for 250 mL it is 1 liter now for 2000mL it is X .
=> x = 2000/250 = 8 liters
C) volume of water in 6L of made up juice is 1500 mL
D) 1 liter - 5 glasses
For 80 glasses it would be 80/5 = 16 glasses
Answer:
case a)
----> open up
case b)
----> open down
case c)
----> open left
case d)
----> open right
Step-by-step explanation:
we know that
1) The general equation of a vertical parabola is equal to

where
a is a coefficient
(h,k) is the vertex
If a>0 ----> the parabola open upward and the vertex is a minimum
If a<0 ----> the parabola open downward and the vertex is a maximum
2) The general equation of a horizontal parabola is equal to

where
a is a coefficient
(h,k) is the vertex
If a>0 ----> the parabola open to the right
If a<0 ----> the parabola open to the left
Verify each case
case a) we have

so


so

therefore
The parabola open up
case b) we have

so



therefore
The parabola open down
case c) we have

so



therefore
The parabola open to the left
case d) we have

so



therefore
The parabola open to the right
Step-by-step explanation:
x+3=8
8-5=3 so x=5
7+5=12 / 12-7=5
12-5=7
