Answer:

The approximate volume of the tube  is 1,005 cm³

Step-by-step explanation:

To find the volume of the tube, we will follow the steps below:

First, write the formula for calculating the volume of a cylinder

volume of a cylinder = πr²h

where r is the radius and h is the height of the cylindrical cardboard tube

from the question given, height is equal to 20 centimeters    and             diameter = 8 centimeters  but diameter = 2r, this implies that r = d/2   hence radius r =8/2 = 4 centimeters

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the formula

volume of a cylinder = πr²h

                                 ≈ 3.14 × 4²× 20

                                   =3.14 × 16× 20

                                    ≈1,005 cm³ to the nearest whole cubic centimeter.

The approximate volume of the tube  is 1,005 cm³

Answer: They are inverses of each other

==========================================================

Explanation:

We'll need to compute h(f(x)) and f(h(x)) to see if we get x each time.

h(x) = 9x-4\\\\h(f(x)) = 9(f(x))-4\\\\h(f(x)) = 9\left(\frac{x+4}{9}\right)-4\\\\h(f(x)) = x+4-4\\\\h(f(x)) = x\\\\

and,

f(x) = \frac{x+4}{9}\\\\f(h(x)) = \frac{h(x)+4}{9}\\\\f(h(x)) = \frac{9x-4+4}{9}\\\\f(h(x)) = \frac{9x}{9}\\\\f(h(x)) = x\\\\

Both composite functions lead to x each time.

The equations h(f(x)) = x and f(h(x)) = x being true means each function is the inverse of the other.

Find the total surface area of this triangular prism.<br> 17 cm<br> 8 cm<br> 2 cm<br> 15 cm
kumpel [21]

Answer:

<em> 200cm²</em>

Step-by-step explanation:

Total surface area of the prism = bh + L(s1+s2+s3)

b is the base of the triangle = 15cm

h is the height of the triangle = 8cm

Perimeter of the triangular base = s1 + s2 + s3 = 8+17+15

Perimeter of the triangular base = 40cm

L is the lateral height = 2cm

Substitute the given values into the formula;

Total surface area of the prism = 15(8) + 2(40)

Total surface area of the prism = 120+80

Total surface area of the prism  = 200cm²

<em>Hence the total surface area of the prism is 200cm²</em>

The problem does not clearly give us the distance from Buffalo to Chicago, so let this be x (in mile) just so I can show you how the total cost is solved. 
The total cost is equal to the sum of the rental fee plus the cost of the additional fee per mile which is equal to 1.50x, and also of the cost of the gasoline which is equal to (x/16)(2.15). Thus, the final answer should be expressed as,
               total cost = 29.95 + 1.5x + 2.15x/16
When the distance is available, this should be easily substituted in the equation above.
