The number of congruent triangles formed from dissecting the polygon using the center point and two adjacent vertices is equal to the number of sides of the polygon. Therefore, for the a polygon with five sides, five congruent triangles are formed and seven for the polygon with seven sides.

The population of a species is modeled by the equation p(t)=-t^4+72t^2+225, where t is the number of years. find the approximate
Shtirlitz [24]

Answer:

The approximate number of years until the species is extinct will be 9 years

Step-by-step explanation:

We are given

The population of a species is modeled by the equation

p(t)=-t^4+72t^2+225

where

t is the number of years

we have to find time when species extinct

we know that any species will be extinct only if population of that species becomes 0

so, we can set P(t)=0

and then we can solve for t

p(t)=-t^4+72t^2+225=0

we can factor it

(t^2+3)(t^2-75)=0

(t^2+3)=0

we get t value as imaginary for this equation

(t^2-75)=0

t=\sqrt{75}

t=8.660

So,

the approximate number of years until the species is extinct will be 9 years
