What is the additive inverse of 19 /- 7?.

The length of the shadow of Hayden is approximately 32 inches.

Charlie and Hayden are standing outside.  Charlie is 64 inches tall and casts a shadow of 30 inches.

Hayden is 68 inches tall. The length of the shadow of Hayden can be calculated as follows:

Using proportion,

64 / 30 = 68 / x

where

x = length of the shadow of Hayden

Therefore,

64 / 30 = 68 / x

cross multiply

64x = 68 × 30

64x = 2040

divide both sides by 64

x = 2040 / 64

x = 31.875

Hence,

Length of the shadow of Hayden = 32 inches

The process of inverse the function is  f⁻¹(x) = x/2.

In math the term function is known as a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.

Here we have to explain the process of solve inverse functions with examples.

While we take the function for examples as

f(x) = 2x.

Now, we have to do the following steps to identify the inverse of the function,

Here the first steps is to replace f(x) by y in the equation describing the function, then we get

=>  y = 2x

Now, we have to interchange x and y in a simple terms now we have to replace replace every x by a y and vice versa, then we get,

=> x = 2y

Then the next step is to Solve for y, here we get

=> y = x/2

Finally replace y by f⁻¹(x)

Therefore, the inverse of the function is

=> f⁻¹(x) = x/2.

The slope of points with same y coordinate but a different x coordinate is 0

this is because change in y is zero

The slope, m of the linear function is calculated using the formula

= change in y / change in x

This is represented mathematically as

m = (y₀ - y₁) / (x₀ - x₁)

In this case change in y is zero since it is same point

y₀ = y₁

And when a number in the numerator is zero the division will result to a quotient of zero and hence the line is a horizontal line

The adjacent angle to ∠PSL is ∠KRM which is ∠2

what is adjacent angle?

Adjacent angles are two angles that share a common vertex and have a common side (or arm) but no common interior points. They are side by side angles and are next to each other. They are not always congruent but they share a common side, usually represented by a line. They can be acute, obtuse or right angles. They can also be complementary angles, meaning they add up to 90 degrees. For example, in a rectangle, the angles across from each other are called adjacent angles, they are both right angles.

The interior angle measurement of a regular polygon with 42 sides is 150 degrees.

The interior angle measure of a regular polygon is determined by the formula (n-2)*180/n, where n is the number of sides of the polygon. In the case of a regular polygon with 42 sides, this formula can be expressed as (42-2)*180/42, which simplifies to 150 degrees. Therefore, the interior angle measure of a regular polygon with 42 sides is 150 degrees. This means that each interior angle of the polygon is 150 degrees. The exterior angle measure of a regular polygon with 42 sides would be 10 degrees, which can be calculated by subtracting the interior angle measure from 180 degrees. Knowing the angle measure of both the interior and exterior angles of a regular polygon with 42 sides is useful for a variety of applications, such as modeling or designing.

In Euclidean geometry, any three factors, while non-collinear, decide a completely unique triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean space). In different words, there's best one plane that consists of that triangle, and every triangle is contained in some plane.

Since division by zero is not defined, 1/0 is not infinity, and 0/0 is not indeterminate.

We must keep in mind that, except in the case of limitations, the value of 1 divided by 0 is infinite. The phrase "infinity" denotes the size of the number. When it comes to limits, we merely presume that limit x's value tends toward something rather than being equal to anything. We thus treat it as infinite.

Since it is not a real number, infinity is only used to symbolise extraordinarily big real numbers. The result of 1 divided by infinity is 0. The quotient of nonzero real numbers that divide infinity is infinity, and the rule of thumb is that any real number divided by infinity is zero.

Answer:

√21 is irrational

Step-by-step explanation:

√21 = 4.58257569495584 which is a non-terminating decimal.

Therefore √21 is irrational.

Answer: No, it cannot be a rational number.

Step-by-step explanation:

A rational number is defined to be a whole number (ex. 1, 2, 3) or can be decimals that continuously repeat the digits after the point. In the case of a square root, they can be rational--but this only applies to perfect squares: √100, √64, √16, etc, which would give an outcome of a whole number. Therefore, √21 is not a rational number, as the decimal value is 4.57257, and is not continuous (ex. 3.666666).

The Area of the rectangle is (40x²+ 49x + 15)cm²

The area of a rectangle in geometry is the region covered by the rectangle in a two-dimensional plane.  The area of the rectangle is the region occupied by a rectangle within its four sides or boundaries.

A rectangle is a sort of quadrilateral, a two-dimensional object with four sides and four vertices. The rectangle's four angles are all right angles or equal to 90 degrees. The rectangle's opposite sides are equal and parallel to one other.

Given that,

Length of rectangle=(8x+5)cm

Breadth of rectangle=(5x+3)cm

Area of rectangle=Length×Breadth

Area of rectangle=(8x+5)(5x+3) = (40x²+ 49x + 15)cm²

Therefore, the Area of the rectangle is (40x²+ 49x + 15)cm²

a. The integral to determine the area enclosed by the inner loop is:

A = ∫0^2π2+4sin(θ)dθ

This integral can be solved using the substitution u = 4sin(θ). This will give us the following integral:

A = ∫0^2π2 + udu

Next, we apply the power rule to the integral and solve for A.

A = 2θ + (u^2)/2 | 0^2π

A = 2θ + (4sin(θ)^2)/2 | 0^2π

A = 2π + 4[1 - cos(2θ)]/2 | 0^2π

A = 2π + 2 - cos(2π)

A = 4π - 1

b. To find the area between the loops, we can use the following integral:

A = ∫2^4π2+4sin(θ)dθ

Using the same substitution, we have:

A = ∫2^4π2 + udu

A = 2θ + (u^2)/2 | 2^4π

A = 2θ + (4sin(θ)^2)/2 | 2^4π

A = 2π + 4[1 - cos(2θ)]/2 | 2^4π

A = 2π + 2 - cos(4π)

A = 4π + 1
