Answer:
5x-6y-12=0
Step-by-step explanation:
...make y the subject y=-6/5x +2
...use the coefficient of x as the gradient,m=-6/5
...for a perpendicular line,find the negative reciprocal of the gradient,5/6
...sub into the eqn y= -1/m(x-a)+b

Given the recursive formula, each terms is five time the previous one.
This means that:
is 5 times
, which means ![f(6)=5f(5)](https://tex.z-dn.net/?f=%20f%286%29%3D5f%285%29%20)
- in turn,
is 5 times
, so we have
. This means that ![f(6)=5f(5)=5\cdot 5f(4) = 25f(4)](https://tex.z-dn.net/?f=%20f%286%29%3D5f%285%29%3D5%5Ccdot%205f%284%29%20%3D%2025f%284%29%20)
- Finally,
So, substituting this back gives
![f(6)=25f(4)=25\cdot 5f(3)=125f(3)](https://tex.z-dn.net/?f=%20f%286%29%3D25f%284%29%3D25%5Ccdot%205f%283%29%3D125f%283%29%20)
In general, since you have
, each time you compute a new term you multiply by a factor of 5, so if
, you have
![f(m)=5^kf(n)](https://tex.z-dn.net/?f=f%28m%29%3D5%5Ekf%28n%29%20)
A is 6 because so is the side across from it
And B is 8 because it the same size just flip it
