Note on how to solve such equation:

This is a quadradic equation. The figure shown is a parabola. This parabola opens downward. Now, this information is not necessary important for this particular situation; however, it needs to be retained for said class or for the near future.

The equation for a quadradic function is: f(x)=x^2+2

when x=-2, y=1

sergejj [24]

Answer:

It will take 2.8 minutes

Step-by-step explanation:

Given

x \to Minutes

y \to Gallons

See attachment for complete question

Required

Time to fill the tube with 46.2 gallons

The attached table is a represents a direct proportional relationship between x and y.

This relationship is:

y = kx

Where k is the constant of proportionality.

When (x,y) = (1,16.5), we have:

16.5 = k*1

16.5 = k

k=16.5

So, we have:

y = kx

y = 16.5x

To calculate the required time to fill 46.2 gallons, we make x the subject

x = \frac{y}{16.5}

Where

y =46.2

x = \frac{46.2}{16.5}

x = 2.8
