You have been assigned a 9 digit identification number.

aniked [119]

Answer:

1,000,000,000 identification numbers are possible.

Step-by-step explanation:

We are assigned a 9 digit identification number.

Each digit is a number from 0 to 9. So, each digit has 10 different choices.

Using the Fundamental Counting Principle (is better than the tree diagram) because it's simpler. To illustrate this, we can attempt to draw a tree diagram.

The first column will be the digits 0 to 9.

Then for each of those digits, we need another 0 to 9.

As you can imagine, the amount of numbers grow exponentially, so using the Fundamental Counting Principle is simpler.

And since we have a 9 digit identification number, with each digit having 10 choices, the total number of identification numbers possible are:

$10\times 10\times 10 \times 10\times 10 \times 10 \times 10 \times 10 \time 10\times 10=10^9=100000000$

So, 1,000,000,000 identification numbers are possible.

Instructions: Find the volume of each figure. Round your answers to the nearest tenth, if necessary.

A cone is a 3-dimensional shape that consists of a circular or flat surface and a curved side. Thus the volume of the given cone is 4.1 $mi.^{3}$

A cone is a 3-dimensional shape that consists of a circular or flat surface and curved side. Its volume can be determined by;

The volume of a cone = $\frac{1}{3}$ $\pi$ $r^{2}$ h

where r is the radius of its flat surface, and h is its height.

From the given question, we have to determine the value of h using the Pythagoras theorem.

Such that;

$/Hyp/^{2}$ = $/Adj 1/^{2}$ + $/Adj 2/^{2}$

$4^{2}$ = $h^{2}$ + $1^{2}$

16 = $h^{2}$ + 1

$h^{2}$ = 15

h = $\sqrt{15}$

Thus the volume of the cone = $\frac{1}{3}$ $\pi$ $r^{2}$ h

= $\frac{1}{3}$ x $\frac{22}{7}$ x $1^{2}$ x $\sqrt{15}$

= 4.0574

Therefore the volume of the given cone is 4.1 $mi.^{3}$

Explain how graphs are used and what their advantages are

bearhunter [10]

Graphs are used to put numbers in a visual form, like a bar graph showing population growth over time. Their advantage is that it helps the viewer understand the situation by seeing it in a easier way.
