The population of a school and is increasing at a rate of 2%per year;

It can be modeled with the equation but needs a starting population number to finish.

Step-by-step explanation:

To find the population in a future year, use the formula:

where A is the amount, p is the starting population, r is 2% or 0.02, and t is the number of years.

Since the population is increasing it is addition. Substitute r=0.02 and t=6. Without a starting population, we cannot find the population in 6 years.

step-by-step explanation:

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
