because the circumstance formula of circle is ,

[tex]\pi \: d[/tex]

Work out the circumference of this circle.
Take it to be 3.142 and give your answer to 1 decimal place.
4 cm

Answers

Answer:

Final Answer 25.12

Step-by-step explanation:

This is very simple you can use two formulas to find the circumfrence of the circle. You can either use C=2πr or C=πd.

For this problem you will be using C=2πr since r is radius and the radius is 4.

C=2*3.14*4

C=6.28*4

C=25.12

Hope this helps.

Part 1 :

☃ [tex] \underline{ \large{ \sf{Vertical \: Line \: Test}}} : [/tex] ⇾ All the relations are not functions. We can determine ( identify ) whether a relation is function or not by drawing a vertical line intersecting the graph of the relation. This is called the vertical line test.

If the vertical line intersects the graph of a relation at one point , the relation is a function.If it cuts at more than one point , it is not a function. It means that if there are more points of the graph of a relation of a vertical line , same first component ( pre - image ) has more images ( second component ) which is not the function by definition.

( See the attached picture )

In the picture ' 1 ' , The vertical line ( dotted line ) cuts the graph at one point ( P ). Thus the graph represents a function.In the picture ' 2 ' , The vertical line ( dotted line ) cuts the graph at two points P & Q. So, the graph does not represent a function.

Part 2 :

☂ The set of all the images of the elements of domain under the function ' f ' is called the range of a function. In other words , the set of second components of a function is called range. We are given the function :

{(–2, 0), (–4, –3), (2, –9), (0, 5), (–5, 7)}

The above numbers [ in bold ] are the range of given function. Now, If we arrange these numbers in ascending order, we get ( -9 , -3 , 0 , 5 , 7 ).

Hence , Choice B [ {y | y = –9, –3, 0, 5, 7} ] is correct.

Sample Response:

The vertical line test is a way to determine if a relation is a function. This test determines if one input has exactly one output on the graph. If any vertical line passes through more than one point on the graph, then the relation is not a function because two different outputs have the same input.

Answers

Answer:

Step-by-step explanation:

1) Find the volume

V = base x width x height = 5 x 0.5 x 2.5 = 6.25 in^3

2) Multiply the nearest whole number x 90

cost = 6 x 90 = $540

3) find the cost of 0.25 in^3

90 : 4 = 22.5

4) find the total cost

540 + 22.5 = $562.50

since its a straight line then put it equal to 180. First we add and then subtract from 180, like this.

52+23=75

what I do is I just add the two degrees you already have and since we know the long line is 180° you would just subtract 180 and 75 :•)

Answer:

x = 12

Step-by-step explanation:

m<BCF and m<CFE are same-side interior angles.

Same-side interior angles are supplementary. This implies that:

m<CFE + m<BCF = 180°

where,

m<CFE = 11x°

m<BCF = 4x°

Plug in the values

11x + 4x = 180

15x = 180

x = 180/15

x = 12
