To find the 5th term of a sequence where f(1) = 2 and f(n) = 4x f(n-1)+9 for each whole number greater than 1, Shane calculates (2 x 4x4x4 4) +9=521. Is this correct? Justify your answer.
(select) Shane (select) each term by 4 to find the next term, and added (select) at the end.
The recursive rule states that (select) the previous term by 4 and adding 9 can generate each
term.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
