Answer:

Surface Area = 150.8 square inch

Step-by-step explanation:

Surface \ Area = 2 \pi r h + 2 \pi r^2  \ \ \ \ \ \ \  \ \ \ \ \ \ [ \ r = 4 , \ h = 2 \ ] \\\\

                    = 2 \pi \times 4 \times 2 + 2 \pi 4^2\\\\=16 \pi + 32 \pi \\\\= 48 \pi \\\\= 150.796 \\\\=150.8 \ square \ inch

If f(x)=2x−1, show that f(f(x))=4x−3. Find f(f(f(x))).
Allushta [10]

Answer: f(f(f(x))  =  8x - 7

Step-by-step explanation:

f(f(x)) means that we are evaluating f(x) with itself, then if f(x) = 2x - 1

f(f(x)) = 2*f(x) - 1 = 2*(2x - 1) - 1 = 4x - 2 - 1 = 4x - 3

f(f(x)) = 4x - 3

Then, we have f(f(f(x)) = 4*f(x) - 3

= 4*(2x - 1) - 3 = 8x - 4 - 3 =  8x - 7
