the number of diagonals that can be drawn in a opolygon of n sides is 1/2n(n-1)-n. If 230 diagonsaals can be drawn how many side

Vitek1552 [10]

Answer:

n = 20

Step-by-step explanation:

The number of diagonal that can be drawn in a polygon of n sides is given by :

$D=\dfrac{n(n-3)}{2}$

If the number of diagonals are 230, then put D = 230 in above formula. So,

$230=\dfrac{n(n-3)}{2}\\\\460=n^2-3n\\\\n^2-3n-460=0$

It is a quadratic equation, the value of n is equal to 20.

It means that for 230 diagonal, there are 20 sides of the polygon.

What is the slope of the line?<br> m =

monitta

Answer:

m=0.25

Step-by-step explanation:

m = (y_2-y_1)/ (x_2-x_1)

Let's get 2 of any coordinates in the graph, for example: (4,2) and (0,1)

m = (1-2)/(0-4) = 1/4 or 0.25

Write as an exponential equation.<br><br> logsub2(1/32)= -5

jok3333 [9.3K]

Answer:

The exponential equation is 2^-5 = 1/32

Step-by-step explanation:

When rewriting the equation, we always take the base (2) and raise it to the answer (-5). Then we set that equal to the term (1/32)

2^-5 = 1/32
