Answer:

8 cm

Step-by-step explanation:

volume of a cylinder is v=pi x r^2 x h

substitute in what we know

3785= pi x r^2 x 19

3785=59.69 x r^2

subtract 59.69 from both sides

3725.31=r^2

square root of 3725.31

61

square root of 61

= about 8

grigory [225]

ANSWER

\Rightarrow y=\frac{1}{2}|x|

EXPLANATION

We want to find the absolute value function for the line in blue.

The general form of an absolute value function is:

y=a|x-h|+k

where (h, k) = vertex

From the line, the vertex of the graph in blue is:

(0,0)

To find a, we have to pick a point (x, y) on the line and input it into the general function.

Let us pick (2, 1).

Therefore, we have:

\begin{gathered} 1=a|2-0|+0 \\ 1=a|2|=2a \\ \Rightarrow a=\frac{1}{2} \end{gathered}

Therefore, the absolute value function is:

\begin{gathered} y=\frac{1}{2}|x-0|+0 \\ \Rightarrow y=\frac{1}{2}|x| \end{gathered}

Which answer lists these numbers in order from least to greatest? -24.8,142,1.13,-2.81,24.1
Vadim26 [7]
The answer is a.  -24.8, -2.81, 1.13, -2.81, 24.1

This is because the larger a negative number is, the lower its value is.  So, when putting numbers from least to greatest, you put the largest negative numbers first, and then work your way up to zero.  Then, you start counting upwards with your positive numbers.
