The radius of a cylindrical construction pipe is 1.5ft. If the pipe is 18ft long, what is its volume? Use the value 3.14 for π ,

olya-2409 [2.1K]

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=1.5\\
h=18
\end{cases}\implies V=\pi \cdot 1.5^2\cdot 18$

Which relationships have the same constant of proportionality between yyy and xxx as the equation 3y=27x3y=27x3, y, equals, 27,

Vera_Pavlovna [14]

Answer:

$y=9x$

$y=\frac{18x}{2}$

$y=\frac{81x}{9}$

Step-by-step explanation:

The given equation is

$3y=27x$

If we isolate $y$ , we can find the constant

$y=\frac{27x}{3}\\ y=9x$

So, the constant is $k=9$ .

Another proportions that have the same constant as the given equation are

$y=9x$

$y=\frac{18x}{2}$

$y=\frac{81x}{9}$

The function a(1) =1/2I^2 describes the area of an isosceles right triangle with leg I. Make a table of values for I=1,2,3 and 4

prohojiy [21]

Functions can be represented using equations, graphs and tables.

The function is given as:

$a(l) = \frac 12 l^2$

When l = 1, we have:

$a(1) = \frac 12 \times 1^2$

$a(1) = 0.5$

When l = 2, we have:

$a(2) = \frac 12 \times 2^2$

$a(2) = 2.0$

When l = 3, we have:

$a(3) = \frac 12 \times 3^2$

$a(3) = 4.5$

When l = 4, we have:

$a(4) = \frac 12 \times 4^2$

$a(4) = 8.0$

Represent the above results as a table, we have:

<u>l a(l)</u>

1 0.5

2 2.0

3 4.5

4 8.0

What is the domain and range of the following function

mel-nik [20]

Answer:

domain: (–∞,∞) or all real numbers

range: (–∞,∞) or all real numbers

Step-by-step explanation:

domain is left to right (x-axis). looking at the graph, as you go from left to right, the x-values are infinitely getting more negative and positive.

range is bottom to top (y-axis). as you go from bottom to top, the y-values are infinitely getting more negative and positive.
