Answer:
The metric system is a system of measurement that uses the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass)
Step-by-step explanation:
The metric system uses units such as meter, liter, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces to measure these.
In addition to the difference in the basic units, the metric system is based on 10s, and different measures for length include kilometer, meter, decimeter, centimeter, and millimeter. Notice that the word “meter” is part of all of these units.
ANSWER

EXPLANATION
The given function is

We rewrite this function to obtain,

We now compare this function to

We have

This implies that,

The vertex is (2,-11).
The focus is



Form the ratio 560/2800 and then mult. the result by 100%:
560
--------- * 100% = 20%
2800
