If f(x) =1/x and g(x) = x - 2 what is f(g(x)) when X = 1​
Fed [463]

Answer:

f(g(x)) = -1

Step-by-step explanation:

f(x) =  \frac{1}{x}  \\  \\ g(x) = x - 2 \\  \\  \implies \: f(g(x)) =  \frac{1}{x - 2}  \\  \\  \implies \: f(g(1)) =  \frac{1}{1 - 2} \\  \\  \implies \: f(g(1)) =  \frac{1}{ - 1} \\  \\  \implies \: f(g(1)) =   - 1

Find the volume and surface area of a sphere with radius 1 yards. Round your answer to two decimal places.
olga55 [171]

Answer:

Volume of the sphere up to two decimal places= 4.19 cubic yards

Surface area of the sphere up to two decimal places  =12.56 square yards

Step-by-step explanation:

Given:

The radius of the sphere= 1 yard

Volume of a Sphere:

                        \frac{4}{3}* \pi *r^3                                                         :\pi =\frac{22}{7} =3.14

               =\frac{4}{3}*3.14*1*1*1

               =4.187 cubic yards

Volume of the sphere up to two decimal places= 4.19 cubic yards

Surface area of the sphere= 4*\pi* r^2

                                           =4*3.14*1*1

Surface area of the sphere up to two decimal places  =12.56 square yards
