Answer:
Step-by-step explanation:
x 1 = π , x 2 = 3 π/ 2
y 1 = - 1, y 2 = 2
The Rate of change = ( y 2 - y 1) / ( x 2 - x 1 )=
= [2 -( -1 )] : ( 3 π /2 - π ) = 3 : π/2 = 6 / π <em>≈ 1.91 </em>
Answer:
n = 20
Step-by-step explanation:
The number of diagonal that can be drawn in a polygon of n sides is given by :

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

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.
If it's a right triangle, and is also an isosceles triangle, namely two sides are of equal length, that means the other non-right-angles are 45° each, so the triangle is a 45-45-90 triangle, and thus we can apply the 45-45-90 rule, so let's do so. Check the picture below.
