Answer:
- y =
+ 7
Step-by-step explanation:
The graph that will lie above the x-axis will be having only positive values throughout its domain,
So, We have to check which graph is having y > 0 for every x.
- y = -
+ 7
clearly y will be negative for many values of x , as coefficient of variable is negative.
- y = - 7
Put x = 0, you will get y as negative .
- y = + 7
Since, Square of anything will always be positive , and here constant term is also positive , so, It will always be positive .
Thus, it is having its graph always above x axis.
Put x = 0 , y = -7, which is negative
14/3 is between 4 and 5, so -14/3 won't be the least or greatest.
The numbers in the order you want are ...
... -5.1, -14/3, -4

Answer: 4 litres of air is held in Braydon’s tank.
Step-by-step explanation:
The law relating pressure to volume is the Boyle's law. It states that the volume of a given mass of gas is inversely proportional to its pressure as long as temperature remains constant. It is expressed as
P1V1 = P2V2
Where
P1 and P2 are the initial and final pressures of the gas.
V1 and V2 are the initial and final volumes of the gas.
From the information given,
V1 = 6 litres
P = 220 psi
P2 = 330 psi
Therefore,
6 × 220 = 330V2
V2 = 1320/330 = 4 litres
