The ratio of black and white keys of piano give correct values of A, B, C as 9, 52, 130.

The ratio of black to white keys of Piano of different sizes are as follow,

Black      A      36        63      90

White     13      B          91        C

From the table of black and white keys relation of proportionality is equal to,

( A / 13 ) = ( 36 / B ) = ( 63 / 91 ) = ( 90 / C )

This implies ,

( A / 13 ) = ( 63 / 91 )  

⇒ A = ( 63 / 91 ) × 13

⇒ A = ( 9 / 13 ) × 13

⇒ A = 9

Similarly,

( 36 / B ) = ( 63 / 91 )

⇒ B = 36 × ( 91 / 63 )

⇒ B = 36 × ( 13 / 9 )

⇒ B = 52

And

( 63 / 91 ) = ( 90 / C )

⇒ C = 90 × ( 91 / 63 )

⇒ B = 90 × ( 13 / 9 )

⇒ B = 130

Therefore, the correct values of A , B, C using the ratio of black and white keys of the piano is equal to 9, 52, 130.

The tangent to a circle equation \(x^2+ y^2=a^2\) at (a cos θ, a sin θ ) is x cos θ+y sin θ= a. The tangent to a circle equation \(x^2+ y^2=a^2\) for a line

y = mx +c is y = mx ± a √[1+ m2].

In Geometry, the tangent is defined as a line touching circles or an ellipse at only one point. Suppose a line touches the curve at P, then the point “P” is called the point of tangency. In other words, it is defined as the line which represents the slope of a curve at that point.

If a tangent line to the curve y = f (x) makes an angle θ with x-axis in the positive direction, then dy/dx = slope of the tangent = tan = θ.

Starting the formation of groups of four bits at the binary point instead of the left end of the number facilitates conversion between binary and decimal numbers, improves organization and readability, simplifies calculations, and aligns the binary number with its decimal equivalent.

When working with binary numbers, it is more common and practical to start forming groups of four bits at the binary point rather than the left end of the number.

The binary point is the equivalent of the decimal point in a binary number system. Starting at the binary point allows for easier conversion between binary and decimal numbers, as well as better organization and readability of large binary numbers.

Forming groups of four bits at the binary point allows us to convert each group into a decimal equivalent. These decimal values can then be added together to obtain the final decimal representation of the binary number.

By starting at the binary point, we can work with smaller groups of bits at a time, which simplifies calculations and reduces the chances of errors. This approach also enables us to track the place value of each group more efficiently.

Additionally, starting at the binary point helps in aligning the binary number with its decimal equivalent. This alignment is crucial when performing arithmetic operations such as addition, subtraction, multiplication, or division on binary numbers.

The table has a constant of proportionality of 0.322

The table that completes the question is added as an attachment

On the table, we have the following points

(x, y) = (9.3, 3)

To determine the constant of proportionality, remove the origin

So, we have

(x, y) = (9.3, 3)

The constant of proportionality of the points is then calculated as

k = y/x

Substitute the known values in the above equation

So, we have

k = 3/9.3

Evaluate the quotient

So, we have

k = 0.322

Hence, the constant of proportionality of the table is 0.322

Karnaugh maps or K-maps are pictorial methods used to minimize Boolean expressions without having to use Boolean algebra theorems and equation manipulations. Option Q is the correct answer.

They provide a visual aid for determining the optimal grouping of terms. Karnaugh maps reduce logic functions more quickly and easily than Boolean algebra simplification. It is a practical tool to use for problems that require minimizing Boolean expressions. There are two common versions of Karnaugh maps: 2-D Karnaugh maps and 3-D Karnaugh maps. A Karnaugh map consists of squares in which each square represents a product term or minterm.

In a two-variable Karnaugh map, there are four squares, whereas in a three-variable Karnaugh map, there are eight squares. Karnaugh maps are read and interpreted from left to right and top to bottom. Terms that are adjacent or touching in the map can be combined to produce a simplified expression. K-maps can minimize up to 4 variables in a 2-D map and up to 6 variables in a 3-D map. Karnaugh maps help reduce the complexity of Boolean expressions and make it easier to implement logic circuits.

Answer:

Slope: 1/2

Step-by-step explanation:

(0,-3) and (6,0)

(0 - - 3)/(6 - 0) = 3/6 = 1/2

Original Coordinates:

A=(-5,-2)

B = (-2,-2)

C= (-2,-5)

D= (-5,-5)

A point (x,y) reflected over the y-axis is equal to (-x,y)

if the family gives up two nights in the hotel, they could afford d) 5 meals

The family has a budget of $800 for meals and hotel accommodations. If they could afford eight nights in a hotel without buying any meals, we can determine the cost of one night at the hotel. To do this, we can divide the total budget by the number of nights:

$800 / 8 nights = $100 per night

Now, let's consider the scenario where the family gives up two nights in the hotel. This would free up $200 from their budget ($100 per night x 2 nights). We can then use this amount to determine how many meals the family can afford by dividing the available funds by the cost of one meal:

$200 / $40 per meal = 5 meals

Therefore, if the family gives up two nights in the hotel, they could afford 5 meals. The correct answer is d. 5.

Energy saving is maintained. This decay is not observed in nature because the basic laws and conservation principles of particle physics do not allow it.

In the decay process you mentioned, n → p e-, the neutron (n) decays into a proton (p) and an electron (e-). This decay violates the conservation of several important quantities. Let's see what is not preserved in this process:

Conservation of charge: In this decay, a neutron (charge = 0) decays into a proton (charge = +1) and an electron (charge = -1). Total charge is not conserved because the neutron is neutral, but the proton and electron have opposite charges.

Conservation of lepton number: Lepton number refers to the number of leptons minus the number of antileptons. A neutron is a baryon, not a lepton, and its decay into a proton (also a baryon) and an electron (a lepton) violates lepton number conservation.

Conservation of baryon number: Baryon number refers to the number of baryons minus the number of antibaryons. Both the neutron and the proton are baryons, so the total baryon number is conserved in this decay. However, the presence of an electron introduces an additional lepton, which breaks the conservation of the baryon number.

Conservation of energy: Energy is generally conserved in the decay process. However, the specific energies of the particles involved may differ. The difference in mass between the neutron and the proton, as well as the electron, are taken into account in the decay energy balance.

In short, the n → p e- decay process violates the conservation of charge, lepton number, and baryon number.

However, energy saving is maintained. This decay is not observed in nature because the basic laws and conservation principles of particle physics do not allow it.

Area of the triangle (A') = 1/2bh

A' = 1/2bh............ Equation 1

Where b = base of the triangle, h = height of the triangle

From the diagram,

Given: b = 12.5 unit, h = 4 unit

Substitute into equation 1

A' = 1/2(12.5)(4)

A' = 25 squared unit.

Also,

Area of the rectangle (A) = Lenght(L)×width(w)

A = Lw............ Equation 2

From the question,

If the area of the rectangle is 40% larger than the area of the triangle

Therefore,

A = 1.4A'

A = 1.4(25)

A = 35 squared unit.

Also given: w = 3\(\frac{1}{2}\) = 7/2

Substitute into equation 2

35 = L×7/2

7L = 35×2

7L = 70

L = 70/7

L = 10 units
