docker41 [41]3 years ago
8 0

Answer:

Step-by-step explanation:

The interior angles of a heptagon add up to 5*180 = 900

So

x + 143 + 116 + 135 + 135 + 116 + 155 = 900     Add up the known angles

x + 800 = 900                                                   Subtract 800 from both sides

x + 800 - 800 = 900 - 800                              Combine

x = 100

Find the geometric mean of the pair numbers 6 and 10
inn [45]

Answer:

The geometric mean between 6 and 10 will be:

G.M=2\sqrt{15}

Step-by-step explanation:

We know that the geometric mean between the two numbers 'a' and 'b' is defined as:

G.M=\sqrt{a\times b}

Now, let us determine the geometric mean between 6 and 10

  • a = 6
  • b = 10

Using the formula

G.M=\sqrt{a\times b}

G.M=\sqrt{6\times 10}

        =\sqrt{60}

        =\:\sqrt{4\times 15}

        =2\sqrt{15}

 Therefore, the geometric mean between 6 and 10 will be:

G.M=2\sqrt{15}

The table shown below shows some values for functions f(x) and g(x). What is/are the solution(s) to f(x)=g(x)? Explain your answ
salantis [7]

Answer:

  x = -1

Step-by-step explanation:

Both tables show a function value of 9 for x = -1.

  x = -1 is the solution to f(x) = g(x), since f(-1) = 9 = g(-1).
