X=46.2
_____________________________
99.2 + 62 = 161.2
180 -161.2 = 19.8
19.8 + 112 = 131.8
180 - 131.8 = 48.2
48.2 - 2 = 46.2
2x squared because x squared is the normal garden (side multiplied by side) and the two doubles it
Answer: (a)
Step-by-step explanation:
Given
The pattern is 2, 4, 16, 256...
From the pattern, we can see that the next term is square of the previous i.e.


So, for the
term, the function is 
For the next term, it is 
So,
![\Rightarrow f(n+1)=[f(n)]^2](https://tex.z-dn.net/?f=%5CRightarrow%20f%28n%2B1%29%3D%5Bf%28n%29%5D%5E2)
200 + 80h = 230 + 70h
80h - 70h = 230 - 200
10h = 30
h = 30/10
h = 3...they will charge the same rate at 3 hrs
3. 17.5feet / 0.07feet/sec = 250 sec
feet cancels feet and sec goes up and 17.5 divided by 0.07
