Answer:
-16
Step-by-step explanation:
f(x)=-8x+8 and g(x) = sqrt x-9 
(f•g)(18)=f(g(18))
g(18)=sqrt(18-9)=sqrt9=3
f(3)=-24+8=-16
 
        
             
        
        
        
Answer:
101.9 sq ft
Step-by-step explanation:
The figure is missing: find it in attachment.
Here we want to find the lateral surface area of the figure, which is the sum of the areas of all faces.
We have in total 5 faces:
- 1 of them is rectangle with sizes (8.5 ft x 3.3 ft), so its area is

- 1 of them is a rectangle with sizes (3.3 ft x 5.1 ft), so its area is

- 1 of them is a rectangle with sizes (6.8 ft x 3.3 ft), so its area is

- Finally, we have 2 triangular faces (top and bottom), so their area is

where
b = 5.1 ft is the base
h = 6.8 ft is the height (because the triangle is a right triangle)
So the area of the triangle is

So the total lateral surface area of the figure is:
