Question

Find the t-number (the number of equilateral grid triangles of side length 1cm that lier inside an isopentagon) of the (5,3,2,3,5) isopentagon.

Find all isopentagons that have a t-number smaller than 20 and explain why there are no others.

There are 2 different isopentagons with t-number 119. Describe these isopentagons and find their perimenters

Answer 1

Wow...
I thought it said *... you may not seek help from other people, including people whom you could contact via the internet*?

Answer 2

im not doing it, i didnt get in, i was just wondering how to do it, because i was interested.

Answer 3

lmao sure, sure...

it is quite easy, just think about it

Answer 4

a) t number = 46
b) The isopentagons that have a t number smaller than 20 are 3,2,1,2,3 and 2,1,1,1,2 and 3,1,2,1,3. There are no others because when you change the longest side to 4 or higher the t number is always over 20.
c) I really don't have a clue.

Answer 5

does anyone know c

Answer 6

the 2 isopentagons for c are (10, 1, 9, 1, 10) and (8, 5, 3, 5, 8)

i found it through trial and error, but i wont give you all the answers, you can draw them and do it yourself.

Answer 7

We define two numerical operations labelled T and R.
The effect of T is to add 1 to a number. For example, if we apply the operation T to the number 2 three times in a row, we obtain 3, then 4, then 5.
The effect of R is to find the negative reciprocal of a number. For example, if we apply the operation R to -3/2 we obtain 2/3. Note that R can never be applied to the number 0.
The operations T and R can be combined. For example, we can turn 0 in to 2/5 by successively applying the operations T, T, T, R, T, T, R, T.
a) Starting with 2, list the numbers produced by successively applying the operations T, R, R, T, R, T, R, T, R.
b) Find a sequence of operations which turns 3/4 into 2/3.
c) Find a sequence of operations which turns 3 into 0.
d) Find a sequence of 20 operations that turns 7 into 0.

Answer 9

u know what bob u sly dog

Answer 10

a) Starting with 2, list the numbers produced by successively applying the operations T, R, R, T, R, T, R, T, R.
This sequence makes 2 a 3 by the end
c) Find a sequence of operations which turns 3 into 0.
To find this sequence you need to get to a negative number then T until you get to 0. The sequence is RTRTTRTT
