The table shows the gallons of fuel remaining after a car travels a certain distance in miles.

the change in fuel remaining from one row to the next in the table is gallon(s).

the change in distance from one row to the next in the table is mile(s).

the slope of the line that runs through the points given in the table is

the slope indicates a

The black will filled by (1) -0.04, (2) 1 , (3)-0.04 and (4) Change in the fuel remaining in each mile.

Explanation:

From the given table we can noticed that the fuel remaining (gallons) decreases as distance (miles).

It is clear that the distance increases by 1 mile for each next row and the remaining fuel is changed for each next row is,

The change in fuel remaining from one row to the next in the table is -0.04 gallons.

The change in distance from one row to the next in the table is 1 mile.

The slope is the rate of change of remaining fuel with respect to change in distance.

The slope of the line that runs through the points given in the table is -0.04.

The slope indicates a Change in the fuel remaining in each mile. The slope is -0.04 it means the remaining fuel decreases by 0.04 gallons in each mile.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
