Cedric is using the tvm solver on his graphing calculator as shown below to
determine the future value of $4800 after it has earned compound interest for
a certain number of years.

according to what cedric has entered into the tvm solver, for how many
years will the $4800 earn compound interest?

the monthly balance will be $75,000

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
