The equation of plane will be x+y-2z=4.

A plane in geometry can go on forever in two dimensions. The absence of width. An illustration of coordinate geometry is a plane. The coordinates of a point in a plane determine its position.

In mathematics, a plane is a two-dimensional, flat surface that never ends. A plane is a two-dimensional equivalent that includes three spatial dimensions, a line, and a point. In some higher-dimensional environments, planes can resemble subspaces, as though the room's walls had been greatly extended. These walls possess a distinct existence all their own, just as in the framework of Euclidean geometry.

The equation of plane can be used to represent a plane surface in three dimensions. There are numerous methods that can be used to find the equation for a plane depending on the input values given. The equation for the plane can be expressed in either cartesian form or vector form.

Hence, the general form of the equation is A(x−x1)+B(y−y1)+C(z−z1)=0

(a) H'(6) is the rate of change of the height of the tree at time t=6, which is the slope of the line tangent to the graph of H(t) at that point. Using the data in the table, we can estimate H'(6) to be 3.2 meters per year. This means that, at t=6, the height of the tree is increasing at a rate of 3.2 meters per year.

(b) H'(t) is the rate of change of the height of the tree at time t. Since H'(t) is twice-differentiable, it is continuous and can take any value between its minimum and maximum values. Therefore, there must be at least one time t, for 2 < t < 10, such that H'(t) = 2.

(c) To approximate the average height of the tree over the time interval 2 ≤ t ≤ 10, we can use a trapezoidal sum with the four subintervals indicated by the data in the table. We have:

Therefore, the average height of the tree over the time interval 2 ≤ t ≤ 10 can be approximated by the trapezoidal sum:

(10 + 14 + 18 + 22) × (2 + 2 + 3 + 3) / 8 = 196/8 = 24.5 meters.

(d) According to the given model, G(x) = 100x/(1+x), if the tree is 50 meters tall, then the diameter of the base of the tree is x = 2, and the rate of change of the height of the tree with respect to time, in meters per year, is given by G'(2) = 100(1 - 2)/(1 + 2)² = -100/9. Therefore, the rate of change of the height of the tree with respect to time, in meters per year, at the time when the tree is 50 meters tall is -100/9 meters per year.

So, if the curve has a horizontal tangent, the values are = k, where k is an integer, and where the curve has a vertical tangent, the values are = (2k + 1)/2, where k is an integer.

A cardiod is a curve defined by the equation r = 1 + cos(θ), where r is the radial coordinate and θ is the angular coordinate. The equation can be re-written as r = 1 + cos(θ) = 1 + 2cos^2(θ/2) for 0 <= θ <= 2π. A curve has a horizontal tangent when its derivative with respect to θ is equal to zero, which means the slope of the tangent line is 0. The derivative of r with respect to θ is dr/dθ = -sin(θ). Thus, the curve has a horizontal tangent when -sin(θ) = 0, or θ = kπ, where k is an integer.

Here,

A curve has a vertical tangent when its second derivative with respect to θ is equal to zero, which means the rate of change of the slope is 0. The second derivative of r with respect to θ is d^2r/dθ^2 = -cos(θ). Thus, the curve has a vertical tangent when -cos(θ) = 0, or θ = (2k + 1)π/2, where k is an integer.

So, the values of θ where the curve has a horizontal tangent are θ = kπ, where k is an integer, and the values of θ where the curve has a vertical tangent are θ = (2k + 1)π/2, where k is an integer.

The derivatives of h(x) is h'(x) = √2 csc ([tex]x^4[/tex] + 1).

We have,

To find h'(x), we need to take the derivative of h(x) with respect to x using the Fundamental Theorem of Calculus.

Given that h(x) = ∫sin(2x - π/4) csc([tex]x^4[/tex] + 1) dt, we can rewrite it as:

h(x) = ∫[a, x] sin(2t - π/4) csc([tex]t^4[/tex] + 1) dt

Now, we'll apply the Fundamental Theorem of Calculus:

h'(x) = d/dx [∫[a, x] sin(2t - π/4) csc([tex]t^4[/tex] + 1) dt]

Using the Leibniz integral rule, we have:

h'(x) = sin(2x - π/4) csc([tex]x^4[/tex] + 1) - sin(2a - π/4) csc([tex]a^4[/tex] + 1)

However, we need to evaluate this derivative at x = π/4 and x = -π/4, so we substitute these values in:

h'(π/4) = sin(2(π/4) - π/4) csc((π/4)^4 + 1) - sin(2a - π/4) csc([tex]a^4[/tex] + 1)

h'(-π/4) = sin(2(-π/4) - π/4) csc((-π/4)^4 + 1) - sin(2a - π/4) csc(a^4 + 1)

Since the derivative is evaluated at the endpoints, the term with sin(2a - π/4) cancels out in both expressions.

Therefore, the derivative simplifies to:

h'(x) = sin(π/4) csc([tex]x^4[/tex] + 1) - sin(-π/4) csc([tex]x^4[/tex] + 1)

simplifying further:

h'(x) = (√2/2) csc([tex]x^4[/tex] + 1) + (√2/2) csc([tex]x^4[/tex] + 1)

Combining like terms, we have:

h'(x) = (√2/2) (csc([tex]x^4[/tex] + 1) + csc([tex]x^4[/tex] + 1))

h'(x) = (√2/2) (2csc([tex]x^4[/tex] + 1))

Finally, simplifying:

h'(x) = √2 csc([tex]x^4[/tex] + 1)

Therefore,

The derivatives of h(x) is h'(x) = √2 csc([tex]x^4[/tex] + 1).

The given expression (5x² + 25x + 20) / 7x is equivalent to the expression [(x² + 2x + 1) / (x - 1)] × [(5x² + 15x - 20) / (7x² + 7x)].

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

The given expression is - (5x² + 25x + 20) / 7x

The other two expression are -

(x² + 2x + 1) / (7x² + 7x)

Let the unknown expression be x.

So according to the question -

(x² + 2x + 1) / (7x² + 7x) × x = (5x² + 25x + 20) / 7x

Cross multiply the polynomials -

x = [(5x² + 25x + 20) / 7x] × [(7x² + 7x) / (x² + 2x + 1)]

Here, it can be seen that (x² + 2x + 1) is the expansion of (x + 1)² and (7x² + 7x) = 7x (x + 1).

Substitute these values into the equation -

x = [(5x² + 25x + 20) / 7x] × [7x (x + 1) / (x + 1)²]

Simplify the equation -

x = (5x² + 25x + 20) / (x + 1)

Here, it can be seen that (5x² + 25x + 20) is the expansion of 5 (x + 4) (x + 1).

Substitute these value into the equation -

x = 5 (x + 4) (x + 1) / (x + 1)

Simplify the equation -

x = 5 (x + 4)

Multiply the numerator and denominator by (x - 1) -

x = 5 (x + 4) (x - 1) / (x - 1)

x = 5x + 20 (x - 1) / (x - 1)

x = 5x² - 5x + 20x - 20 / (x - 1)

x = 5x² + 15x - 20 / (x - 1)

So the unknown expression is 5x² + 15x - 20 / (x - 1).

Verify by substituting -

[(x² + 2x + 1) / (x - 1)] × [(5x² + 15x - 20) / (7x² + 7x)]

Here, it can be seen that (x² + 2x + 1) is the expansion of (x + 1)² and (7x² + 7x) = 7x (x + 1).

Substitute these values into the equation -

[(x + 1)² / (x - 1)] × [5 (x + 4) (x - 1) / 7x (x + 1)]

5 (x + 4) (x + 1) / 7x

Simplify the equation -

5x + 20 (x + 1) / 7x

5x² + 5x + 20x + 20 / 7x

5x² + 25x + 20 / 7x

This expression is equivalent to the original expression.

Therefore, the unknown expressions are (5x² + 15x - 20) and (x - 1).

The shear force diagram of a simply supported beam is parabolic when it is a linearly varying distributed load.

What is a shear force diagram?

A shear force diagram depicts the shear force's variation throughout the length of the beam.

Examples of internal forces that are produced in a structure when loads are applied include shear force and bending moment. Failures often result from loading in one of two ways:

A beam can be damaged either a) by being sheared across its cross section or b) by being bent excessively.

It is possible to define shear force as the algebraic sum of the loads to the left or right of a point, provided that doing so restores vertical equilibrium.

For the shear force diagram of a simply supported beam to be parabolic, then the load on the beam should be linearly varying distributed load.

The slope or load will vary linearly if the shear force diagram is parabolic.

Step-by-step explanation:

The x-intercepts are approximately x = 1.305, 5.695. These are the x-coordinates where the parabolic function crosses the x-axis.

What is parabola?

A parabolic function is a type of mathematical function that describes a parabolic curve or parabola. A parabola is a U-shaped curve that is symmetrical about its axis of symmetry.

The equation y = x^2 - 3x - 7 represents a parabolic function with its vertex located at (-3/2, -7). To find the x-coordinates of the x-intercepts (also known as the roots or zeros), we need to solve the equation x^2 - 3x - 7 = 0. This can be done using various methods, such as the quadratic formula or factoring.

Using the quadratic formula, the x-intercepts can be found as follows:

x = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = -3, c = -7, and √ represents the square root symbol.

So,

x = (-(-3) ± √((-3)^2 - 4(1)(-7))) / 2(1)

x = (3 ± √(9 + 28)) / 2

x = (3 ± √37) / 2

Hence, the x-intercepts are approximately x = 1.305, 5.695. These are the x-coordinates where the parabolic function crosses the x-axis.

The sum of the infinite geometric series is 64/7.

Geometric progression is a sequence of numbers such that the ratio of two consecutive numbers is the same for whole sequence.

This ratio is common ratio.

Geometric series is the sum of the numbers in the geometric progression.

Sum of an infinite geometric series can be found by the formula,

S = a / (1 - r)

where a is the first term and r is the common ratio.

Given series is 16 - 12 + 9 - 27/4 + ...

a = 16

r = -12 / 16 = -3/4

S = 16 / (1 - -3/4)

  = 16 / (1 + 3/4)

  = 16 / (7/4)

  = 64/7

Hence the required sum is 64/7.
