It is the blue one. By doing the vertex formula we can see the x value of the vertex is -3/4. The blue one best represents that as the negative A value shows the parabola will be facing down too and have a maximum not a minimum for the vertex
Volume (tank)=base x heitht
base is a squeare, so base=side²
Volume(Tank)=side² * height
600 m³=side² * 6 m
side²=600 m³/ 6 m
side²=100 m²
side=√(100 m²)=10 m.
answer: the side of the base is 10 m.
To work out how many miles the distance from the airport to the beach, we can use 1km ≈ 0.62 miles
To get from 20km from 1km, we multiply by 20
If we do the same to 0.62
0.62 x 20 = 12.4 miles
Next step is to add this on to the 500 miles they travelled by plane
500 + 12.4 = 512.4 miles
