The student population in a high school increases by 4% a year. when it opened, the school had 996 students. how many students will there be in 3 years

1120 students.

Step-by-step explanation:

there is a formula that we can use which is:

initial value*(1 + percent increase)^number of years

number of students=996*(1+0.04)^3 = 1120.36

therefore, approx. 1120 students.                                                        

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
