For this type of problem, plug the -4 into the graph for x. So where is the line at x = -4??
y = 4 where x = -4.
That's the same as saying: "what is the y-value when x = -4?)
f(-4) = y = 4

Volume of Pipe is 226 ft³.

Step-by-step explanation:

Given:

Cylindrical Shape Pipe having

Height = 18 ft

Diameter = 4 ft

∴ $Radius =\frac{Diameter}{2}=\frac{4}{2}=2\ ft$

To Find:

Volume of Pipe = ?

Solution:

Formula for Volume of Cylinder is given by

$\textrm{Volume of Cylinder}=\pi (Radius)^{2} \times Height$

Substituting the given values we get

$\textrm{Volume of Pipe}=3.14\times 2^{2} \times 18\\\\\textrm{Volume of Pipe}=226.08\\\\\therefore \textrm{Volume of Pipe}=226\ ft^{3}$

Volume of Pipe is 226 ft³.

Anastasy [175]

Answer: 19.4

Step-by-step explanation:

Given

Profit is given in terms of the selling price

$y=-5x^2+194x-900$

to get the maximum price, differentiate y w.r.t x

$\frac{\mathrm{d} y}{\mathrm{d} x}=-5\times 2x+194$

Put $\frac{\mathrm{d} y}{\mathrm{d} x}=0$ to get maximum value

$10x=194\\x=19.4$

Thus, the company must sell it at 19.4
