What square number divided by another square number = 9

The graphs of the functions y = cos 2x and y = 1 - sin² x intersect at x = 0 and x = π over the interval 0 ≤ x ≤ π.

To find the intersection points of two functions set the two functions equal to each other, simplify the equation using trigonometric identities, and then solved for the values of x that satisfied the equation. And check the values if the given function is satisfied or not.

Here we have

The functions y = cos 2x and y = 1 - sin²x  

And the interval 0 ≤ x ≤ π

To find the x-values where the graphs of the functions y = cos 2x and y = 1 - sin² x intersect over the interval 0 ≤ x ≤ π,

We need to set the two functions equal to each other and solve for x.

So, we have:

cos 2x = 1 - sin² x

Using the identity cos 2x = cos²x - sin² x, we can rewrite this as:

cos²x - sin² x = 1 - sin² x

On Simplifying, we get the:

cos² x = 1

Taking the square root of both sides, we have:

cos x = ±1

Since we're only considering the interval 0 ≤ x ≤ π,

the possible values of x are:

x = 0, π/2, π

Now, we need to check which of these values of x satisfy the original equation:

For x = 0, cos 2x = cos 0 = 1 and 1 - sin² x = 1 - sin² 0 = 1,

So they intersect at x = 0.

For x = π/2, cos 2x = cos π = -1 and 1 - sin² x = 1 - sin² (π/2) = 0,

So they don't intersect at x = π/2.

For x = π, cos 2x = cos 2π = 1 and 1 - sin² x = 1 - sin² π = 1,

So they intersect at x = π.

Therefore,

The graphs of the functions y = cos 2x and y = 1 - sin² x intersect at x = 0 and x = π over the interval 0 ≤ x ≤ π.

The perimeter of the regular polygon is approximately 61.2 m

The area of the regular polygon is approximately 282.8 m²

From the question, we are to determine the perimeter and area of the given polygon.

The given polygon is an octagon.

Consider the right triangle drawn in the octagon. The length of a side of the regular octagon is twice the length of the base of the right triangle.

Let the base of the right triangle be b.

In the triangle, the measure of the angle close to the center of the octagon is 22.5° (That is, (360° / 2) ÷ 2).

From SOH CAH TOA,

We can write that

sin (22.5°) = b/10

b = 10 × sin (22.5)

Length of a side of the octagon = 2 × 10 × sin (22.5)

Thus,

Perimeter of the octagon = 8 × 2 × 10 × sin (22.5)

Perimeter of the octagon = 61.2293

Perimeter of the octagon ≈ 61.2 m

Area of the octagon,

Area of a regular octagon = (Perimeter × Apothem) / 2

|Apothem|² = 10² - (10 × sin (22.5))²

|Apothem|² = 100 - 14.64466

|Apothem|² = 85.35534

|Apothem| = √85.35534

|Apothem| = 9.2388

Thus,

Area of the octagon = (61.2293 × 9.2388) / 2

Area of the octagon = (565.68525684) / 2

Area of the octagon = 282.8426

Area of the octagon ≈ 282.8 m²

Hence,

The area is 282.8 m²

Answer:

The volume of the pyramid is approximately 25,920,000 cubic feet.

Step-by-step explanation:

The Great Pyramid of Khufu is one of the most famous pyramids in Egypt, located in Giza. Its original height was 146.7 meters (481 feet), but due to erosion and the loss of its outer casing, it now stands at a height of 138.8 meters (455 feet). The base of the pyramid is a square with sides measuring 230.4 meters (755.9 feet).

To find the volume of the pyramid, we can use the formula:

V = (1/3)Bh

where V is the volume, B is the area of the base, and h is the height of the pyramid.

First, we need to convert the dimensions of the pyramid to feet. The height of the pyramid is 455 feet, and the base of the pyramid is a square with sides of 755.9 feet.

The area of the base is:

B = side^2 = (755.9 ft)^2 = 571536.81 sq ft

The volume of the pyramid is:

V = (1/3)Bh = (1/3) × 571536.81 sq ft × 455 ft ≈ 2.592 × 10^7 cubic feet

Therefore, the dimensions of the Great Pyramid of Khufu are approximately 755.9 feet for each side of the base, and 455 feet for the height. The volume of the pyramid is approximately 25,920,000 cubic feet.

The integral of the rational expression is equal to I = - 1.414 · ㏑ |x + 3.372| + 2.194 · ㏑ |x - 2.372| + 0.219 · ㏑ |x - 1| + C.

In this problem we find the case of a rational expression, whose integral must be determined. This can be done by means of partial fractions method, that is, decompose the rational expression into a sum of fractions. First, write the entire rational expression and use partial fractions method:

(x² - 9) / (x³ - 9 · x + 8)

[(x - 3) · (x + 3)] / [(x + 3.372) · (x - 2.372) · (x - 1)]

A / (x + 3.372) + B / (x - 2.372) + C / (x - 1)

(x - 3) · (x + 3) = A · (x - 2.372) · (x - 1) + B · (x + 3.372) · (x - 1) + C · (x + 3.372) · (x - 2.372)

x² - 9 = A · (x² - 3.372 · x + 2.372) + B · (x² - 2.272 · x - 3.372) + C · (x² + x + 7.998)

x² - 9 = (A + B + C) · x² + (- 3.372 · A - 2.272 · B + C) · x + (2.372 · A - 3.372 · B + 7.998 · C)

Solve the system of linear equations:

A + B + C = 1

- 3.372 · A - 2.272 · B + C = 0

2.372 · A - 3.372 · B + 7.998 · C = - 9

(A, B, C) = (-1.414, 2.194, 0.219)

(x² - 9) / (x³ - 9 · x + 8) = - 1.414 / (x + 3.372) + 2.194 / (x - 2.372) + 0.219 / (x - 1)

Second, integrate the resulting equation:

I = - 1.414 ∫ [1 / (x + 3.372)] dx + 2.194 ∫ [1 / (x - 2.372)] dx + 0.219 ∫ [1 / (x - 1)] dx

I = - 1.414 · ㏑ |x + 3.372| + 2.194 · ㏑ |x - 2.372| + 0.219 · ㏑ |x - 1| + C

Answer:

dy/dx = (2xy^7 - 4y) / (y - 6x^2y^6)

Step-by-step explanation:

To find dy/dx by implicit differentiation, we differentiate both sides of the equation with respect to x.

Differentiating 4x + In y=x²y^6 with respect to x, we get:

4 + (1/y) dy/dx = 2xy^6 + 6x^2y^5 dy/dx

Now, we can isolate dy/dx by moving the terms that contain it to one side of the equation, and moving the rest to the other side:

(1/y - 6x^2y^5) dy/dx = 2xy^6 - 4

Dividing both sides by (1/y - 6x^2y^5), we get:

dy/dx = (2xy^6 - 4) / (1/y - 6x^2y^5)

Simplifying this expression, we can write:

dy/dx = (2xy^7 - 4y) / (y - 6x^2y^6)

We can start by multiplying the numerators and denominators separately:

(2x - 2) / 21 * 49 / (1 - x)

= [(2(x - 1)) / 21] * [49 / -(x - 1)]

Notice that (1 - x) = -(x - 1), so we can simplify the expression further:

= [(2(x - 1)) / 21] * [49 / -(x - 1)]

= [(2(x - 1)) / 21] * [49 / (x - 1)]

= [2 * 7] / [3 * (x - 1)]

= 14 / (3x - 3)

Therefore, the simplified expression is 14 / (3x - 3).

The value of x when the tangent intersect is 270 degrees.

The angle theorem between intersecting tangents states that the measure of the angle formed by two tangents that intersect at a point outside a circle is equal to one-half the positive difference of the measures of the intercepted arcs.

Therefore,

90 = 1 / 2(x - (360 - x))

90 = 0.5(x - 360 + x)

90 = 0.5(2x - 360)

90 = x - 180
