The parks department is monitoring level of a lake the change in water level of the lake is modeled by a third degree polynomial function p(x)a) what do the x-values when p(x)=0 tell you about the real world situation? i’m just really confused on what is being asked.

Solution:

Consider a polynomial of degree 3,P(x)=0, whose roots are .

It means whether temperature remains constant or there is rise in temperature or temperature decreases the volume of water in lake decreases. it can't increase because if you think temperature is constant chances are you can say surely that earth may soak water.

So, if are roots of the polynomial P(x)=0, it means with increase in day water level of pond is decreasing.

Consider, , then

=  Level of water in the  pond on   th day.=

=  Level of water in the pond on   th day.=

 =  Level of water in the  pond on   rd day.=

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
