Answer:

9 Sides

Step-by-step explanation:

According to the Question,

  • Given That, The sum of the interior angles(s), in an n-sided polygon can be determined using the formula s=180(n−2), where n is the number of sides

Therefore, The sides do a polygon have if the sum of the interior angles is 1,260°.

Put The Values in Formula, we get

1260=180(n−2)

n-2 = 7

n=9 (9 Sides)

Express each of the following in logarithmic form ​
vodomira [7]

Answer:

See explanation.

Step-by-step explanation:

(i)  5^3 = 125

log 5^3 = log 125

Using the rule log a^n = n log a

3 log 5 = log 125.

(ii) 3^-2 = 1/9

-2 log 3 = log 1/9

(iii)   10^-3 = 0.001

-3 log 10 = log 0.001

(iv)   81^3/4 = 27

3/4 log 81 = log 27.

How would I graph this and find the solution to this system. <br> y=-1/2x+4
Lesechka [4]

Answer: Easy, graph and solution

Step-by-step explanation: First what you want to do  use the slope intercept form to find the slope and y intercept; -1/2 and y intercept (0,4). Any line can be graphed using 2 points. Select two x values, plug them into the equation to find the corresponding y values. Solution

1.) Step; x and y

Table:

             0║4

             8║0

  • All you had to do is divide 0=-x/2 +4= .  (8) For the x intercept you get 8and for y you get 4 because you divided  0=-0/2+4
