Answer:

You divide by five because it's the common factor of 5 and 15 in the 4th line of work and the goal is to solve for x. The only way to get x alone in the inequality 5x>15 is to divide each side by 5. This would give you x and 3, hence the answer: x > 3

[tex]\frac{5x}{5} =x\\\\\frac{15}{5} =3[/tex]

Here,

The goal is to construct a trigonometric equation with only answers at

x = 1 and x = 2.

f(x) = A sin(Bx+C+D)

=> B + C + D + A = 0 (equation 1)

=> Equation 2: A sin(2B + C + D) = 0

=> B + C sin A = 0 (equation 3)

=> Sin(2B+C) = A = 0 (equation 4)

Since sin(x) = 0 when x is a multiple of, formulae 3 and 4 can be rewritten as follows:

=> B + C = nπ (equation 5)

=> 2B + C = mπ (equation 6)

with numbers n and m. When we simultaneously solve equations 5 and 6 for B and C, we obtain:

=> B = (m - n)π/2 (equation 7)

=> C = nπ - B (equation 8)

=> When x = 1, C = /2 - /2 = 0.

=> When x = 2, C =  − /2 = 3/2.

Thus, the result is as follows:

the product of (x + 3/x)² is x² + 6 + 9/x².

Why it is and what is Algebra?

To find the product of (x + 3/x)², we can use the formula for squaring a binomial:

(a + b)² = a² + 2ab + b²

In this case, we have a = x and b = 3/x, so we can substitute these values into the formula and simplify:

(x + 3/x)² = x² + 2(x)(3/x) + (3/x)²

= x² + 6 + 9/x²

Therefore, the product of (x + 3/x)² is x² + 6 + 9/x².

To find:-

Answer:-

Here since the given triangle is a right angled triangle, we may use the trigonometric ratios . We can see that perpendicular and base are involved in this question whose measures are "x" and "√10" respectively with respect to 60° angle. So here we may use the ratio of tangent as , in any right angled triangle,

[tex]\implies\tan\theta =\dfrac{p}{b} \\[/tex]

and here p = x , and b = √10 . So on substituting the respective values, we have;

[tex]\implies \tan\theta = \dfrac{x}{\sqrt{10}} \\[/tex]

Also the angle here is 60° , so that;

[tex]\implies\tan60^o =\dfrac{x}{\sqrt10} \\[/tex]

The value tan60° is √3 , so we have;

[tex]\implies \sqrt3 =\dfrac{x}{\sqrt10}\\[/tex]

[tex]\implies x =\sqrt{10}\cdot \sqrt{3}\\[/tex]

[tex]\implies x =\sqrt{10\cdot 3} \\[/tex]

[tex]\implies x =\sqrt{30} \\[/tex]

The value of √30 is approximately 5.48 , so that;

[tex]\implies \underline{\underline{\red{\quad x = 5.48\quad }}} \\[/tex]

Therefore the value of x is approximately 5.48 .

Answer:

The length of side x in simplest radical form is [tex]\sqrt{30}[/tex].

Step-by-step explanation:

From inspection of the given right triangle, we can see that the interior angles are 30°, 60° and 90°. Therefore, this triangle is a 30-60-90 triangle.

A 30-60-90 triangle is a special right triangle where the measures of its sides are in the ratio  1 : √3 : 2.  Therefore, the formula for the ratio of the sides is b: b√3 : 2b where:

We have been given the side opposite the 30° angle, so:

[tex]\implies b=\sqrt{10}[/tex]

The side labelled "x" is the side opposite the 60° angle, so:

[tex]\implies x=b\sqrt{3}[/tex]

Substitute the found value of b into the equation for x:

[tex]\implies x=\sqrt{10}\sqrt{3}[/tex]

[tex]\textsf{Apply the radical rule:} \quad \sqrt{a}\sqrt{b}=\sqrt{ab}[/tex]

[tex]\implies x=\sqrt{10 \cdot3}[/tex]

[tex]\implies x=\sqrt{30}[/tex]

Therefore, the length of side x in simplest radical form is [tex]\sqrt{30}[/tex].

[tex]\hrulefill[/tex]

We can also calculate the length of side x using the tangent trigonometric ratio:

[tex]\boxed{\tan \theta=\sf \dfrac{O}{A}}[/tex]

where:

From inspection of the given right triangle:

Substitute these values into the formula:

[tex]\implies \tan 30^{\circ}=\dfrac{\sqrt{10}}{x}[/tex]

[tex]\implies \dfrac{\sqrt{3}}{3}=\dfrac{\sqrt{10}}{x}[/tex]

[tex]\implies x\sqrt{3}=3\sqrt{10}[/tex]

[tex]\implies x=\dfrac{3\sqrt{10}}{\sqrt{3}}[/tex]

Rationalise the denominator by multiplying the numerator and denominator by √3:

[tex]\implies x=\dfrac{3\sqrt{10}}{\sqrt{3}}\cdot \dfrac{\sqrt{3}}{\sqrt{3}}[/tex]

[tex]\implies x=\dfrac{3\sqrt{10}\sqrt{3}}{3}[/tex]

[tex]\implies x=\sqrt{10}\sqrt{3}[/tex]

[tex]\implies x=\sqrt{10\cdot3}[/tex]

[tex]\implies x=\sqrt{30}[/tex]

Therefore, the length of side x in simplest radical form is [tex]\sqrt{30}[/tex].

The Converse of the Pythagorean Theorem is proved below.

What is Pythagoras Theorem ?

Pythagoras' theorem is a fundamental principle in geometry that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The converse of the Pythagorean theorem states that if a triangle has sides of length a, b, and c, where c is the longest side, and a² + b² = c², then the triangle is a right triangle.

To prove the converse of the Pythagorean theorem, we can use the fact that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. That is, if a triangle has sides of length a, b, and c, where c is the longest side and c² = a² + b², then the triangle is a right triangle.

Proof:

Suppose we have a triangle ABC, with sides of length a, b, and c, where c is the longest side. Assume that a² + b² = c². We want to show that triangle ABC is a right triangle.

We will use the Law of Cosines to show that angle C is a right angle. The Law of Cosines states that for any triangle ABC with sides of length a, b, and c opposite angles A, B, and C, respectively:

c² = a² + b² - 2ab cos(C)

Substituting a² + b² = c² into this equation, we get:

c² = c² - 2ab cos(C)

2ab cos(C) = 0

cos(C) = 0

Since 0 is the cosine of 90 degrees, this implies that angle C is a right angle. Therefore, triangle ABC is a right triangle.

Thus, this completes the proof of the converse of the Pythagorean theorem.

The height and slant height of the cone is 7.64 inches and 9.38 inches respectively.

What is volume of cone ?

The volume of a cone is the amount of space occupied by the cone and is given by the formula:

[tex]Volume of a cone = (1/3) * pi * r^2 * h[/tex]

where pi is the mathematical constant approximately equal to 3.14, r is the radius of the circular base of the cone, and h is the height of the cone.
The formula for the volume of a cone can be derived by using calculus or by dividing the cone into a series of infinitesimally thin circular disks, calculating the volume of each disk, and summing up the volumes to obtain the total volume of the cone

According to the question:
To solve this problem, we need to use the formulas for the volume and surface area of a cone:

[tex]Volume of a cone = (1/3) * pi * r^2 * h[/tex]

Surface area of a cone = [tex]pi * r * (r + \sqrt{h^2 + r^2})[/tex]

where r is the radius of the base, h is the height, and pi is a mathematical constant approximately equal to 3.14.

First, we need to find the radius of the cone. The diameter is 10 inches, so the radius is half of that, or 5 inches.

The volume of the cone is given as 300 cubic inches. We can plug in the values we know and solve for the height:

[tex]300 = (1/3) * pi * 5^2 * h[/tex]

[tex]h = 300 / ((1/3) * pi * 5^2)[/tex]

[tex]h \approx 7.64 inches[/tex]

So the height of the cone is approximately 7.64 inches.

Next, we can use the Pythagorean theorem to find the slant height of the cone.

[tex]slant height^2 = radius^2 + height^2[/tex]

[tex]slant height^2 = 5^2 + 7.64^2[/tex]

[tex]slant height \approx 9.38 inches[/tex]

So the slant height of the cone is approximately 9.38 inches.
