A class measured the radius and circumference of various circular objects. The results are plotted on the graph below. Does there appear to be a proportional relationship between the radius and circumference of a circle? Explain your reasoning

Answers

Answer 1

Answer:yes it is proportional.

Step-by-step explanation:

it goes through the origin & the line is straight

Answer 2

This does not in anyway show that there is a proportional relationship because the constant of proportionality (k) varies.

Also, if a straight line is drawn to connect the points, it won't pass through the center of origin (0, 0).The relationship is not proportional.

Recall:

In a proportional graph, the line plotted passes through the center of origin (0, 0).Also, each point on the line, (x, y) will always have a constant of proportionality that is the same, i.e. k = y/x.

Thus,

From the graph given:

For the first point, (3, 18) , k = 18/3 = 6

For the second point, (4, 25), k = 25/4 = 6.25

Third point, (6, 38), k = 38/6 = 6.33

Thus, this does not in anyway show that there is a proportional relationship because the constant of proportionality (k) varies.

Also, if a straight line is drawn to connect the points, it won't pass through the center of origin (0, 0).The relationship is not proportional.

Answer:

Step-by-step explanation:

when it's just x by itself, the coefficient is always 1. But when solving the equation, you do 3x+3*3. So not sure what you mean. When you solve it you multiply x by 3. But in that equation right now it's 1

What are the coordinates of B and how is that the answer ?

Answers

Step-by-step explanation:

Point A = (-1, -3).

Midway of AB = (-3, 2).

Let Point B = (x, y).

Then (-1, -3) - (-3, 2) = (-3, 2) - (x, y).

=> (2, -5) = (-3-x, 2-y).

We have -3 - x = 2 and 2 - y = -5.

So x = -5 and y = 7.

Hence, point B = (-5, 7).

4(x+9) = x+9

Answers

4 ( x + 9) = x + 9 (remove the parantheses)

4x + 36 = x + 9 (move the terms)

4x - x = 9 - 36 (collect like terms and calculate)

3x = -27 (divide both sides)

solution : x = -9

Answer:

Solution given:

4(x+9) = x+9

4x+36=x+9

4x-x=9-36

3x=-27

x=-27/3

x=-9.

For example, if your answer is (4253,6475), enter it like this: (42/53, 64/75) If there is no solution, enter "no"; if there are infinitely many solutions, enter "inf."

Answers

Answer:

No solutions / "no"

Step-by-step explanation:

y = 3x + 2

y = 3x - 6

Since both equations are equal to y, you can set them equal to each other.

3x + 2 = 3x - 6

subtract 3x from both sides

2 = -6

This equation is not true, therefore your answer is no solutions.

i need help finding the area .

Answers

Answer:

149 in²

Step-by-step explanation:

The figure is composed of 3 rectangles.

A( lower) = 5 × 7 = 35 in²

A(middle) = 10 × 6 = 60 in²

A(right) = 6 × 9 = 54 in²

Sum the 3 areas for total area

Total area = 35 + 60 + 54 = 149 in²

Answer:

149 inches square.

Step-by-step explanation:

Given,

length (l) = 7 in.

breadth (b) = 5 in.

Area (A1) = l×b

= 7×5

= 35 inches square

now,

length = 9 in.

breadth= 6 in.

Area (A2) = l×b

= 9×6

= 54 square inches

again,

length = 10 in.

breadth = 6 in.

Area (A3) = l×b

= 10×6

= 60 square inches

Area of irregular figure = A1+ A2+ A3

= 35 +54 + 60

= 149 in. square

if an object has a mass of 15 g and a volume of 3 mL what is its density

Answers

Answer:

Given the mass of the object = 15g

Given the volume of the object = 3 mL

Density = ?

Step-by-step explanation:

We have two values of an object that is mass of the object and volume of the object. Now we are required to find the Density of the object. In order to find the density of the object, we have to divide the given mass with the given volume. Below is the calculation of the density.

Density = Mass / Volume

Density = 15g / 3 mL

Density = 5 g/ml

Answer:

Density = 5g/mL

Step-by-step explanation:

Given that the mass of the Object is

= 15g

Given that the volume accumulated is

= 3mL

We find,

Density =?

Theerefore, both the given mass of the object and its accumulated volume will be divided.

Mass ÷ Volume

15g ÷ 3mL

=5g/mL

Density = 5g/mL

[tex]\frac{(V^{2} -V^{1})}{V^{1} }[/tex] x 100 = ?

Plug in the numbers, V1 being 25 and V2 being 19.

[tex]\frac{19-25}{25}[/tex] x 100 = ?

19 - 25 = -6

Put -6 as the new numerator.
