Alake is stocked with 1,500 young trout. if the number of the original trout alive after x years is given by the function p(x)=1500e^-0.4x, when will there be 300 of the original trout left?

The function gives the number of the original trout alive after x years. When the number of the original trout alive is 300, then

Solve this equation:

after 4.024 year (or 5 year if round to the whole number of years)

4400

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
