Answer:

f(x) = 0.99x + 0.3

Step-by-step explanation:

f(x) = 1.29 + 0.99(x - 1)

Distribute

f(x) = 1.29 + 0.99x - 0.99

Combine like terms

f(x) = 0.99x + 0.3

Answer:

The radius of the cylinder is  r=6  meters.

Step-by-step explanation:

To determine:

What is radius?

Information Fetching and Solution Steps:

The volume of the cylinder = 1,921.68 cubic meters

\pi \approx 3.14

The height = 17 m

As the formula of the volume of the cylinder

                                    V=\:\pi \:r^{2} \:h

The radius can be determine as

                                   r^{2} \:=\:\frac{V}{\pi \:h}

                                     r=\sqrt{\frac{V}{\pi \:\:h}}

                                      \:r=\sqrt{\frac{1921.68}{\left(3.14\right)\:\left(17\right)}}

\mathrm{Remove\:parentheses}:\quad \left(a\right)=a

                                      r=\sqrt{\frac{1921.68}{3.14\cdot \:17}}

\mathrm{Multiply\:the\:numbers:}\:3.14\cdot \:17=53.38

                                       r=6  meters

Therefore, the radius of the cylinder is  r=6  meters.  

Keywords: radius of the cylinder, volume of cylinder
