Triangle 1: A(6,6), B(12,9), C(9,6) Triangle 2: A' (2,2), B’ (4,3), C (3,2)
What scale factor was used to transform triangle 1 to triangle 2?
To transform Triangle 1 to Triangle 2, a scale factor of
A was used.

step-by-step explanation:

no of data

divide by no of mode

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
