A nature center has a fish tank in the shape of a rectangular prism. The tank is 10 feet long, 8 ¼ feet wide, and 6 feet tall. The nature center's caretaker filled 80% of the tank with water. What was the volume of the water in the tank, in cubic feet?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
