Mathematics
1 answer:
Lyrx [107]3 years ago
3 0

Answer:

Step 1       Distributive Property

Step 2      Associative Property

Step 3      Multiplication Rule

Step 4      Zero Exponent Rule    

Step 5      Definition of an Exponent

Step-by-step explanation:

To evaluate or simplify expressions with exponents, we use exponent rules.  

1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.

2. Multiplication Rule: When we multiply terms with the same bases, we add exponents.

3. Division Rule: When we divide terms with the same bases, we subtract exponents.

4. Zero Exponent Rule: When we have a base to the exponent of 0, it is 1.

5. Negative Exponent Rule: A negative exponent creates a fraction.

6. Power to a Power Rule: When we raise an exponent to an exponent, we multiply exponents.

7. Distributive Property: When we have exponents with parenthesis, we apply it to everything in the parenthesis.

Step 1       Distributive Property

Step 2      Associative Property

Step 3      Multiplication Rule

Step 4      Zero Exponent Rule    

Step 5      Definition of an Exponent

What is the distance points for (2,-2) and (0,-9)
Ksivusya [100]

The distance between two points (2,-2) and (0,-9) is 7.3 units, which is obtained by graphical method and formula method.

Step-by-step explanation:

The given is,

         Two points are (2,-2) and (0,-9)

Step:1

         By graphical method,

         For two points (2,-2) and  (0,-9)

                  First point (2,-2)

                             The values of x=2 and y=-9 noted in the graph

                  Second point (0,-9)

                              The values of x=0 and y=-9 noted in the graph

                  Now join the two points, measure the distance between the two points,

                   Distance between points are 7.3 units.

                                          ( OR )

Step:1

        By formula method,

              Distance =   \sqrt{(x_{2}- x_{2})  ^{2}+ (y_{2}-y_{1})  ^{2}  }

       Where,

               ( 2,-2) are (x_{1},y_{1})

               (0,-9) are (x_{2},y_{2})

       From the values,

                             = \sqrt{(0- 2)  ^{2}+ (-9+2)  ^{2}  }

                            =  \sqrt{(- 2)  ^{2}+ (-7)  ^{2}  }

                            = \sqrt{4+49  }

                            = \sqrt{53}

                            = 7.280

                            ≅ 7.3

            Distance = 7.3

Result:

           The distance between two points (2,-2) and (0,-9) is 7.3 units, which is obtained by graphical method and formula method.
