The circumference of a circle:
C = 2 r π
If r = 5.1 cm:
C = 2 · 5.1 · 3.14 = 32.028 cm ≈ 32.03 cm
Answer:
The approximate value of the circumference is 32.03 cm ( rounded to the nearest hundredth ).

The graph shows the number of pictures a traffic camera takes each minute.
BigorU [14]

Answer:

The point (8, 4) on the graph represent that:

'Every 8 Minutes, 4 Pictures are Taken.'

Step-by-step explanation:

Since the graph has not been provided lets try to explain in actual context.

The question states that the Graph shows the <u>Number of Pictures</u> a traffic camera takes <u>Each Minute.</u>

This tells us that we have a two-dimensional graph, of x with y where:

x: denotes <em>Each Minute</em>

y: denotes <em>Number of Pictures taken</em>

<em />

<em>Thus x is our </em><u><em>independent </em></u><em>variable that changes, and as a result of it so does y, our </em><u><em>dependent </em></u><em>variable. </em>

As such we can conclude that any point from the graph is of the form

(x,y).

Here the question asks what does the point (8,4) represent. So based on the information above we know that here:

x=8 and y=4

which if read on the graph it would indicate that:

On the x-axis of minutes we are looking at minute 8 and on the y-axis of number of pictures taking we are looking at the value 4. Thus:

(8,4) represents that Every 8 Minutes, 4 Pictures are Taken.

What is the value of the expression? Show all work.<br> -9 - 6 + 8 ÷ -4 * -2?
nadya68 [22]

Step-by-step explanation:

To do Order of Operations, we need to go with the order of the formula, PEMDAS.

P= Parenthesis

E= Exponents

M= Multiply (Whatever Comes First in Equation: M and D)

D= Divide

A= Addition (Whatever Comes First in Equation: A and S)

S= Subtraction

---------------------------------------------

So, we need to start with parenthesis, there aren't any, so we move on to Exponents.

There are no Exponents either, so we start with division, then multiplication.

(We always have to go left to right).

So,

-9 - 6 + <u>8 / -4</u> x -2

-9 - 6 + <u>-2 x -2</u>

-9 - 6 + 4

Our problem is:

-9 - 6 + 4

We do subtraction, then addition. (Left to Right)

<u>-9 - 6 </u>+ 4

<u>-15 + 4</u>

-11.

Therefore, the answer is -11.

Which rule is an example of rigid transformation?
GalinKa [24]

We know that

Rigid transformation:

A rigid transformation (also called an isometry) is a transformation of the plane that preserves length.

Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations"

so, it's length must be preserved

now, we will check each option

option-A:

we have (x,3y)

y-value changes but x-value will remain same

It changes length

so, this is not rigid transformation

option-B:

we have (3x,y)

x-value changes but y-value will remain same

It changes length

so, this is not rigid transformation

option-C:

(2x, y+2)

It changes length of x-value

but it is only shifting y-value

so, it changes length

so, this is not rigid transformation

option-D:

Both shifts values

but it's length will always be same

so, this is rigid transformation..............Answer
