Answer:
![f^{-1}(x)=\sqrt[3]{x}-6](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7Bx%7D-6)
Step-by-step explanation:
![\sqrt[3]{x}=y+6](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%3Dy%2B6)
![\sqrt[3]{x}-6=y](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D-6%3Dy)
Let x be the size of the small room and 2x, the big room
The larger room requires 3 coats and the smaller, 2 coats
All requires exactly 8 gal.
2.x + (2x).3 = 8 Gal, 8x = 8 and x = 1 (size of te smallest)
if it's the small room, then it will need 2 coats or 2x1 = 2 Gal, and the paint left is 8-2 = 6 Gal.
if it's the large one, 6x or 6 Gal, and remaining 2 Gal
Answer:
Step-by-step explanation:
area of triangular endface = ½×6×8 = 24 cm²
area of rectangular endface = 4×8 = 32 cm²
area of each endface = 24+32 = 56 cm²
area of each 3×10 face = 30 cm²
area of 3×4 face = 12 cm²
area of base = 8×3 = 24 cm²
surface area = 2×56 + 2×30 + 12 + 24 = 208 cm²
