The equation relating the circumference (CA) of ®A to the circumference (CB) of ®B is a(CA) - b(CB) = 0.

A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object.

Now it is given that,

scale factor from ®A to ®B = b/a

⇒Ks = b/a

∵ Ks = A/B

By comparison we get,

A = b

and B = a

Thus, circumference (CA) of ®A = 2πr = 2πb

and, circumference (CB) of ®B = 2πr = 2πa

Dividing both we get,

circumference (CA) of ®A/circumference (CB) of ®B = b/a

by cross multiplication we get,

a * circumference (CA) of ®A = b * circumference (CB) of ®B

or, a * circumference (CA) of ®A - b * circumference (CB) of ®B = 0

or, a(CA) - b(CB) = 0

this is the required equation.

Thus, the equation relating the circumference (CA) of ®A to the circumference (CB) of ®B is a(CA) - b(CB) = 0.

Step-by-step explanation:

If participation continues at the same rate, the participation in 2013 will be 5.75million i.e. 5750000 .

Slope(m) for given two points (x₁,y₁) and (x₂,y₂)  is calculated using the formula

m=(y₂-y₁)/(x₂-x₁)

In the given question ,we will take year as x coordinate and the participation as y coordinate.

Given " The participation in 2004 was 8milllion" , So

The point becomes (2004,8)

and "the attendance in 2006 was 8.5 million" So

the point becomes (2006,8.5)

Now as we have the two points (2004,8) &  (2006,8.5) ,

x₁=2004 , y₁=8 , x₂=2006 , y₂=8.5

slope can be calculated as

m=(8.5-8)/(2004-2006)

m=0.5/2

m=0.25

Hence , the rate of change is 0.25 million participants per year.

It is given in the question that rate of change remains constant.

To predict the attendance for the year 2013.

Let the attendance for the year 2013 be x.

we have (2004,8) and (2013,x)

let m=0.25, x₁=2004 , y₁=8 , x₂=2013 , y₂=x

m=(y₂-y₁)/(x₂-x₁)

Substituting the values above we get  

[tex]0.25=\frac{8-y}{2013-2004} \\ \\ 0.25=\frac{8-y}{9}[/tex]

By cross multiplying we get

[tex]0.25*9=8-y\\ \\ 2.25=8-y\\ \\ y=8-2.25[/tex]

[tex]y=5.75[/tex]

Therefore , If participation continues at the same rate, the participation in 2013 will be 5.75million i.e. 5750000.

The coordinates of the midpoint of a segment with the given endpoints will be (-7.5, 3.5).

Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).

Then the coordinate of the mid-point of the line segment is given as,

(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]

The endpoints are A(-12, 2) and C(-3,5).

Then the coordinates of the midpoint of a segment with the given endpoints will be

(x, y) = [(- 12 - 3) / 2, (2 + 5) / 2]

we are given the phone number  555- 3703, which contains 7 digits : 3 5s, 2 3s, 1 0s, and 1 7s,

The formula for the probability of an event is:

no.of possible cases / total number of cases.

For the final  result, we need to find the  individual digits' probabilities and multiply them.

So, the probability of first digits: 3/7

equation of the line that passes through the point (8,3) is

3 = -2 + c

The equation for a straight line is y=mx + c, where c is the height at which the line intersects the y-axis, also known as the y-intercept, and m is the gradient.

Since the equation of line is

y = mx + c

where m represents the slope

m = -1/4 (given)

and point for  which we have to find the equation is (8,3)

plugging each and every value in the equation

we get the equation of the line ,

The calculation rule is to consider chirp rate as input and temperature as output. Then count the number of chirps, divide it by four and add forty to it. Therefore, the standard formula can be written as:

Estimated temperature = [tex](\frac{1}{4} )[/tex] chirp rate+[tex]40[/tex]

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The spherical cover of a lamp has a mass of 780 g and a diameter of 25 cm. If you were to use it to carry water.

We know that the density of the water is 1 g / cm³. Then the mass of the water will be given as,

Density = mass / volume

What is a solution's equilibrium?

Differential equations can have solutions called equilibrium solutions when the derivative along those solutions equals zero. In other words, at that solution, the slope is a horizontal line.

Consider the following potentials:

U(x) = [tex]x^{4}[/tex]

U(x ) = [tex]x^{6 } - x^{4}[/tex]

U( x ) = [tex]x^{4} + x^{3}[/tex]

All three of these potentials have an equilibrium point at x=0. All three of these potentials are such that the second derivative of U(x) at this equilibrium point is zero.

However, you should convince yourself (perhaps by plotting these potentials) that in the first case the equilibrium is stable, in the second case it is unstable, and in the third case the equilibrium is, as you put it, "stable in one direction but unstable in the other".

The second derivative is zero tells us nothing about stability.

If quadrilateral WXYZ is a rhombus and ∠XYZ = 110°, then ∠ZWY is equal to 110°.

Rhombus is a quadrilateral that is similar to a parallelogram since its opposite sides are parallel with each other and its opposite angles are equal. All four sides of a rhombus are of equal length and the diagonals bisect each other at 90°.

Rhombus has 4 interior angles whose sum is 360°. The opposite angles of a rhombus are equal to each other while the adjacent angles are supplementary.

∠XYZ is the opposite angle of ∠ZWY and opposite angles of a rhombus are equal to each other.
