In 1998 there were 305 students who graduated from high school. In 2019, there were 356 students. What is the rate of change in the number of students? 1. About 1 student per year
2. about 51 students per year
3. about 2 students per year
4. about 5 students per year

3. about 2 students per year

Step-by-step explanation:

The rate of change would be the difference in the number of students divided by the number of years passed.

So, rate of change =

=

So it's around 2 students per year.

I hope this is correct and helps!

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
