The volume of the cube = (2)(1.3)(1.3) cubic meters,

= 4.16 cubic meters,

According to question a quarter is filled with petrol.
So the volume full of petrol = 0.25 × 4.16 cubic meters = 1.04 cubic meters.

The remaining portion needed to be filled = (4.16-1.04 )m^3 = 3.12m^3

So a (3.12× 1000) litres = 3210 litres of petrol will be needed to fill this tank.

Part a: what is the initial value of the function? what does it mean in the context of the situation?

Answer:

Initial value = 10, slope = 4

Step-by-step explanation:

Initial value is the point where x takes its lowest value. In this case it is x = 0 and y = 10. Rate of change is the slope at a given point. Because this is a first order equation graph the slope is always the same. And in this case it is 4 as for every 1 unit of x the y goes 4.
