A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.

Given:

The polynomial zeros are given as:

x = 7, x = -1 and x = -3

x - 7 = 0, x + 1 = 0 and x + 3 = 0

So, f(x) = (x - 7)(x + 1)(x + 3)

f(x) = (x - 7)(x² + 4x +3)

f(x) = x³ -3x² -25 x -21

Now, Rational function g(x)

g(x) = f(x) / (x² - x + 2)

After Factorizing

g(x) = (x-2) - 25x+ 25 /  (x² - x + 2)

The slant asymptote is the quotient i.e. x - 2

Hence, the slant asymptote of the function g(x) is x - 2

So, the discontinuities of g(x)

g(x) = (x³ -3x² -25 x -21) /  (x² - x + 2)

Set the denominator to 0

x² - x + 2 = 0

(x - 2)(x + 1) = 0

x= 2 or x= -1.

So, the discontinuities and their types are:

Essential discontinuity at x = 2

Removable discontinuity at x = -1

Step-by-step explanation:

The ratio 3:4 into percentage is 75%.

3/4 is expressed as 75% in terms of percentage.

Percentage:

In mathematics, a percentage is a number or ratio that represents a fraction of 100. This is one way of representing a dimensionless ratio between two numbers. Other methods include ratios, fractions, and decimals. Percentage is often indicated by writing a "%" sign after the number.

According to the Question:

The fraction 3/4 to an equivalent fraction with the denominator equal to 100

(3 × 25) / (4 × 25) = 75/100

Now,

75/100 is expressed as 75% in terms of percentage.

Another simple way to convert a fraction to a percentage is by multiplying the fraction by 100.

In this case, 3/4 × 100 = 75%

Thus, 3/4 is expressed as 75% in terms of percentage.

The statement which is given as , "The product of permutation matrices is again a permutation matrix." is True.

A permutation matrix is a square matrix whose entries are either 0 or 1 and has exactly one "1" in each row and each column. In other words, it is a matrix that represents a permutation of the rows (or columns) of the identity matrix.

When two permutation matrices are multiplied, the result is another square matrix with exactly one "1" in each row and each column. To see why this is true, consider two permutation matrices, A and B. Suppose that A is a m x m matrix and B is a m x m matrix. The product of these two matrices is another m x m matrix, C = AB.

Each entry in the matrix C is given by the dot product of the corresponding row in A and the corresponding column in B. If the row in A has a "1" in the i-th position and the column in B has a "1" in the j-th position, then the i,j-th entry in C will be "1".

Since both A and B are permutation matrices, each row in A and each column in B has exactly one "1". This means that each row in C will have exactly one "1", and each column in C will also have exactly one "1". Hence, C is also a permutation matrix.

The surface area of the prism is 60 sq meters.

A cuboid is a three-dimensional closed figure which has volume along with surface area.

The volume of a cuboid is the product of its length, width, and height.

We know, The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.

Given prism has 9 m of length, 6 m of width, and 2 m of height.

Therefore, The surface area of the prism is,

The result is 45a^3b^4+4b

The given expression is 45a^3b^4+36a^2b^5 ÷ 9a^2b^4 First, we will simplify the term 36a^2b^5 ÷ 9a^2b^4 by dividing the coefficients and subtracting the exponents of the variables.

36 ÷ 9 = 4

a^2 ÷ a^2 = a^(2-2) = a^0 = 1

b^5 ÷ b^4 = b^(5-4) = b^1 = b

So, 36a^2b^5 ÷ 9a^2b^4 = 4b

Now, we can substitute this value back into the original expression:

45a^3b^4+4b

We cannot simplify this expression any further since the terms do not have the same power of the variables.

Answer: 0,5

x = 0
y = 5

Answer: (0,5)

Step-by-step explanation:

Since "y" is equal to -6x+5 everywhere you see a "y" you can replace it with -6x+5.

-2x-6x+5=5

Combine like terms

-8x+5=5

Isolate x (subtract 5 from both sides)

-8x=0

Solve for x

x=0

Now that you have the value for "x" you can substitute the value into either equation and solve for y

-2(0)+y =5

y=5

If Keshawn is 1.45 meters tall. At 12 noon, he measures the length of a tree's shadow to be 15.05 meters. the height of the tree to the nearest hundredth of a meter is 2.02 meters.

To find the height of the tree, we can use the similar triangles method. Let's call the height of the tree "h".

Since Keshawn and the tree are standing in the same spot, the same light source is casting their shadows, so the ratios of their shadow lengths to their heights are equal. This means we can set up the following proportion:

1.45 / h = 15.05 / 10.8

We can solve for "h" by cross-multiplying:

h = 15.05 * 1.45 / 10.8

h = 2.02 meters

Therefore, the height of the tree to the nearest hundredth of a meter is approximately 2.02 meters.

The value of the square root of 9 is 3.

The square root of a number is the value that, when multiplied by itself, gives the original number. In this case, we want to find the square root of 9.

We can start by finding the perfect squares that are less than 9. The perfect squares less than 9 are 1 and 4. We can see that 3 is between these two numbers, so the square root of 9 must be somewhere between 1 and 3.

We can test whether 3 is the square root of 9 by squaring it: 3 x 3 = 9. This confirms that 3 is indeed the square root of 9.

Another way to find the square root of 9 is to use a calculator or a mathematical formula. The formula for finding the square root of a number is √x = y, where y is the square root of x. In this case, x is 9, so we have √9 = 3.

The area of the enclosure is approximately 128.6 acres

To find the area of the trapezoid ABCD, we first need to find the lengths of its parallel sides. Let's use the fact that the angles of a quadrilateral add up to 360 degrees:

Angle ABC = 124 degrees

Angle BCD = 85 degrees

Angle CDA = 96 degrees

Angle DAB = 360 - 124 - 85 - 96 = 55 degrees

Now we can use the tangent function to find the lengths of the sides:

tan(2 degrees) = (height of AB) / (distance between Anna and Benito)

(height of AB) = (distance between Anna and Benito) × tan(2 degrees)

(distance between Anna and Benito) = (713 - 690) / tan(2 degrees) ≈ 18490.3 ft

(height of AB) ≈ 429.4 ft

Similarly, we can find the height of CD:

tan(3 degrees) = (height of AD) / (distance between Anna and Deon)

(height of AD) = (distance between Anna and Deon) × tan(3 degrees)

(distance between Anna and Deon) = (725 - 690) / tan(3 degrees) ≈ 8639.5 ft

(height of AD) ≈ 459.6 ft

Now we can use the trapezoid area formula:

Area = (height of AB + height of CD) × (sum of the parallel sides) / 2

Area = (429.4 + 459.6) × ((18490.3 + 8639.5) / 2) / 5280 ≈ 128.6 acres

The smallest pair of 4-digit numbers such that the difference between them is 303 and their HCF is 101 are 1010 and 1313.

HCF (Highest Common Factor) of two numbers, which is the largest number that divides both numbers evenly.

Let's call the smaller of the two numbers "x". The larger number would be "x + 303".

The HCF of these two numbers must be 101, which means that 101 must be a factor of both x and x + 303.

To find the smallest possible value of x, we need to find the smallest number that is divisible by 101 and also a 4-digit number.

The smallest multiple of 101 that is a 4-digit number is

=> 101 x 10 = 1010.

Therefore, x = 1010.

The larger number would be

=> x + 303 = 1010 + 303 = 1313.

To check if the HCF of these two numbers is indeed 101, we can use the Euclidean Algorithm or the Prime Factorization method to find the HCF.

The area of the polygon will be equal to 58.1 square units.

A polygon's area is the region that it occupies. Polygons can be both regular and irregular in shape. Triangles, squares, rectangles, pentagons, hexagons, and other basic polygons are used in geometry. Each of these polygons has its own area.

A pentagon is a given polygon. The apothem is the perpendicular line drawn from the octagon's midpoint to the base of one of its sides.

The formula for determining the area of a regular polygon is expressed as

Area = a² × n × tan 180/n

For the function y = 3x - 1, the correct conclusion is C.As the value of x increases, the value of y increases.

As the value of x increases, the value of y increases.

In this function, y is dependent on the value of x. The variable x is multiplied by 3 and then subtracted by 1 to find the value of y. As the value of x increases, the value of y will also increase because it is being multiplied by 3.

For example, if x = 1, then y = 3(1) - 1 = 2. If x = 2, then y = 3(2) - 1 = 5. As you can see, as the value of x increases, the value of y also increases.
