Answer: 
The distance between the coordinates of the two points is measured by the Distance formula
Step-by-step explanation:
The distance between two points P(x1,y1) and Q(x2,y2) is measured by Distance formula i.e Distance= 
(x2-x1)²+(y2-y1)²
So, the distance between the two points P(5,-3) and Q(2,4) can be measured by
Distance PQ = (2-5)²+(4-(-3))²
PQ = (-3)²+7²
PQ= 9+49
PQ=58
So,the distance of PQ is
Hello! The answer for your question would be $32. This is because if Archie earns $4 a week and there are 4 weeks in each month, and he works for 2 months, then 4*4 for one week would equal $16. This times 2 would equal $32 therefore, Archie earned $32 dollars for 2 months of doing chores.
So the radius is from (-2, -3) to (-2, 0) which is a distance of 3The general form for the equation of a circle is:

Answer:
a. Concentration of nitrogen in water draining from fertilized lands
b. Quantitative
c. Water draining from fertilized lands
Step-by-step explanation:
a. Here we are evaluating the Concentration in miligrams of Nitrogen per liter of water, that drains from fertilized lands.. So thats what is defined as the variable.
b. When we talk about qualitative variblaes, we refer to variables that we can't define with numbers. For example the colour of a car, that's a qualitative variable. In this problem, can put a number on the nitrogen concetration. When we can measure the variable with numbers we consider it to be a quantitative variable. Therefore this is a quantitative variable
c. The implied population is the population where we want to interfer the analysis. In here we want to know the concentration of water draining from fertilized lands. So we are using random samples from a lake, and we extrapolate that analysis to a bigger universe, that it´s the water draining from fertilized lands
