Q1: What is the distance between (2, 3) and (-2, 7)? Round to the nearest tenth, if necessary.

The answer to your question is 5.7

Step-by-step explanation:

Data

Point A = (2, 3)

Point B = (-2, 7)

Process

To find the distance between points A and B use the formula of the distance between two points, substitute and simplify.

Formula

dAB =

-Identify wich is the value of x1, y1, x2, y2

        x1 = 2   y1 = 3  x2 = -2  y2 = 7

-Substittion

dAB =

-Simplification

dAB =

dAB =

dAB =

-Result

dAB = 5.65 ≈ 5.7

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

answer: idk
