l. axes (of a graph)

The axes of a graph are the two lines that define the coordinate system and divide the plane into four quadrants. These lines are called the x-axis and the y-axis. The x-axis is the horizontal line and the y-axis is the vertical line. The point where the two axes intersect is called the origin and is identified by the coordinates (0,0). The x-axis is typically used for the independent variable and the y-axis is used for the dependent variable. When plotting data on a graph, the x-axis is often labeled with the independent variable and the y-axis is labeled with the dependent variable. The axes of a graph provide a reference for determining the position of a point and are used for displaying data and drawing maps.

Multiplying each side of a false equation by the same number will result to a false equation

A false equation refers to equation where the left hand side of the equation is not equal to the right hand side of the equation.  

False equations are not useful and hence in math, converted effort are made towards getting a true equation.

A true equation refers to an equation where each side of the equation are same hence the equality sign is truly represented.

Example of true equation say 2x = 10 for x = 5

2 * 5 = 10 correct

multiplying the two sides by 3 results to

6x = 30

plugging in x = 5

6 * 5 = 30

for false equation, say 2x = 10 for x = 6

2 * 6 = 10 incorrect

multiplying the two sides by 3 results to

6x = 30

plugging in x = 6

6 * 6 = 30 incorrect hence false equation remains false

a) A cross-section passing through the diagonals of opposite faces of a cube = 21 square inches.

b) A cross-section parallel to the base of a cube = 64 square inches.

c) A cross-section perpendicular to the base and passing through the diagonals of the base and opposite face of a right rectangular prism = 70 square inches.

d) A cross-section parallel to the base of a right rectangular prism = 300 square inches.

What is a cross-section?

A cross-section is a representation of a three-dimensional object as it would appear if it were sliced by a plane, revealing the internal structure of the object. The resulting shape that is formed is known as the cross-section.

a cross-section passing through the diagonals of opposite faces of a cube with edges that are 7 inches long and a diagonal that is approximately 10 inches = 21 square inches (since it will be a right triangle with legs of 7 inches and hypotenuse of 10 inches)

a cross-section parallel to the base of a cube whose edges are 8 inches long = 64 square inches (since the base will be a square with sides of 8 inches)

a cross-section perpendicular to the base and passing through the diagonals of the base and opposite face of a right rectangular prism that is 24 inches wide, 7 inches long, and 12 inches tall and measures 25 inches along the diagonal of the base = 70 square inches (since it will be a right triangle with legs of 12 inches and 24 inches and hypotenuse of 25 inches)

a cross-section parallel to the base of a right rectangular prism that is 3 inches long, 7 inches wide, and 11 inches tall = 300 square inches (since the base will be a rectangle with length of 3 inches and width of 7 inches)

Hence,

a) A cross-section passing through the diagonals of opposite faces of a cube = 21 square inches.

Substituting the value of x and solving the function we get the value of y as y = 1

To evaluate the co-ordinate point (x, y) for the function

y = f(x) = -1.25x -0.25,

you need to substitute the value of x into the function and solve for y.

If x = -1,

then y = f(-1) = -1.25×(-1) - 0.25 = 1.25 - 0.25 = 1.

Therefore, the coordinate point (x, y) for the function:

y = f(x) = -1.25x - 0.25 when x = -1 is (-1, 1).

A function in mathematics is a collection of values connected by a predetermined rule or formula.

Step-by-step explanation:

You want to use a table of logarithms to evaluate the product 13.81×14.28.

Logarithms turn a multiplication problem into an addition problem, along with some table look-ups. The basic idea is ...

  log(ab) = log(a) +log(b)

To find the logarithm of a number, it can help to write it in scientific notation. This puts one non-zero digit to the left of the decimal point and expresses the multiplier as a power of 10. The first attachment shows a number in scientific notation.

A log table is used to find the logarithm of the mantissa of the number in scientific notation. The result will be a decimal fraction between 0 and 1.

You start by locating the first digits of the mantissa in the left column of the table, and additional digits across the top. The second attachment shows a portion of a table of logarithms with the relevant table entries identified.

The log of 13.81 = 1.381×10¹ is found by locating 13 in the left column, and the next digit, 8, at the top of the table. The final digit, 1, is located at the top of the portion of the table labeled Mean Difference. The number in the Mean Difference column is added to the number found in row 13, column 8: 1399 +3 = 1402. This sum is the mantissa of the logarithm of 13.81. (See the third attachment for the naming we're using.)

Similarly, the log of 14.28 is found in row 14, column 2, and the value in Mean Difference column 8 is added to that: 1523 +24 = 1547.

The characteristic of each logarithm is the corresponding characteristic of the number in scientific notation. For each of these numbers, it is 1.

The logarithm of the product is the sum of these logarithms:

  log(1.381×10¹ · 1.428×10¹) = 1.1402 +1.1547 = 2.2949

The value corresponding to this logarithm is found by a procedure that is the reverse of the lookup procedure.

Our logarithm has a characteristic of 2, and a mantissa of 0.2949.

First, we locate the highest number in the table that is less than or equal to the mantissa. Here, that value is 2945, located in row 19, column 7 of the table. The value we want, 2949, is 4 more than this, so we look in the Mean Difference table on row 19 for a value of 4. That is found in column 2.

The mantissa of the antilog of 2949 is the row number (19) with the column numbers appended: 1972. The decimal point for this is located to the right of the leading digit: 1.972.

The characteristic of the antilog is the characteristic of the logarithm: 2.

Then the antilog in scientific notation is ...

  10^2.2949 = 1.972×10²

In standard form, this is ...

  1.972×10² = 197.2

The desired product is found to be 13.81×14.28 ≈ 197.2.

__

Additional comment

Different tables of logs may show the interpolation values (Mean Difference) differently. These values are intended to aid in interpolating between table values so that you can find logs and antilogs of numbers with 4 significant digits. (Larger tables let you work with more significant digits.)

In general, the number of significant digits in the values you work with will be less than or equal to the number of significant digits in the logs in the table. Here, the table has 4-digit logs, so our result, 197.2, can have at most 4 significant digits. (The actual product is 197.2068.)

When the characteristic of a number is negative, care must be taken to use correct values for the mantissa and characteristic of the logarithm. Table values are logs of numbers between 1 and 10, and are positive. The log of 0.003949 would be the sum of the negative characteristic -3 and the positive logarithm mantissa 0.5965. That sum would be -2.4035 = (-2) + (-0.4035). Since we want to keep the fractional part positive, we sometimes add and subtract a large positive number. The logarithm of 0.003949 might be expressed in this way as 7.5965-10, effectively the log of 3.949×10⁷×10⁻¹⁰.

After solving, the measure of angle BCD is 25 degree.

In the given question, we have to find the measure of angle BCD.

As we know that the angle of line is 180 degree.

From the graph we can see that angle yAD = 25 degree

So, the value of angle DAB = 180 - 25

The value of angle DAB = 155

As we know that in the quadrilateral the sum of opposite angle is equal to 180 degree.

So ∠DAB + ∠BCD = 180

155 + ∠BCD = 180

Subtract 155 on both side, we get

∠BCD = 25 degree

Hence, the measure of angle BCD is 25 degree.

The measure of angle BCD is 45 degrees.

To solve for the measure of angle BCD, we need to use the Triangle Angle Sum Theorem which states that the measure of the angles of a triangle add up to 180 degrees.

Let us use the following figure to illustrate the calculation:

We have angle BCD with unknown measure, angle ABC with measure 45 degrees, and angle ACD with measure 90 degrees.

We can now use the Triangle Angle Sum Theorem to find the measure of angle BCD.

180 degrees = 45 degrees + 90 degrees + x

x = 180 degrees - 135 degrees

x = 45 degrees

Therefore, the measure of angle BCD is 45 degrees.

then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = x² + 2x + 1 ← is in standard form

with a = 1 and b = 2 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{2}{2}[/tex] = - 1
