The length of the base of the triangle is 16 m and the height of the triangle is 10 m

A polygon having three edges and three vertices is called a triangle. It is one of the fundamental geometric forms. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.Use the equation area = 1/2 * base * height to determine a triangle's surface area.

The basic Properties of a triangle :

The length of the base = b m

The height of the triangle = b - 6 m

The area of the triangle = 80 m²

Therefore,

(1/2)*b*(b-6) = 80

⇒ b² - 6b = 160

⇒ b² - 6b - 160 = 0

⇒b² - 16b + 10b - 160 = 0

⇒b(b-16) + 10(b- 16) = 0

⇒(b-16)(b =10) =0

The value of b = 16 and b = -10

The value of b is 16 as -10 is negetive and cannot be the length of the triangle.

The height of the triangle = b-6 = 10 m

Answer:

Step-by-step explanation:

Let's call the common difference of the arithmetic sequence "d", and the first term of the sequence "a". Then we can write two equations based on the information given:

a + 3d = 57 (the 11th term is 57)

a + a + 3d = 29 (the sum of the first and fourth terms is 29)

Solving for the first equation for "a", we get:

a = 57 - 3d

Substituting this expression for "a" into the second equation, we get:

57 - 3d + 3d = 29

57 = 29

So the first three terms of the arithmetic sequence are:

a = 57 - 3d

a + d = 57 - 2d

a + 2d = 57 - d

Solving for "d", we can find the value of "a", and then use the equations above to find the first three terms of the sequence

For the given tossing of number cube and its frequency outcome, the probability on landing a number greater than 4 is 18/60.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

As given in the question

Total number of tossing a number cube = 60

Number of times greater than 4 comes up = 10 + 8 (frequency of is 10 and frequency of 6 is 8)

⇒Number of times greater than 4 comes up = 18

Probability of getting number greater than 4

=  (frequency of getting 5 and 6) / (total number of trials)

⇒ probability of getting number greater than 4  = 18 / 60

the volume of the solid under the surface z = 9x + 5y² and above the region bounded by x = y² and x = y³ is: 89/210

Solid, liquid, and gas are the three different states of matter. Solids have a distinct volume and form. Although they have a specific capacity, liquids adopt the form of the container. Gases lack a distinct volume or form. Solids do not adapt to the shape of the container in which they are stored since they have a distinct shape, as well as mass and volume. In addition to having a high density, solids also feature closely packed particles. The volume of space that what a solid covers is assessed by its volume. It is calculated using the volume of unit cubes required to completely fill the solid.

Firstly, we will find bounds:

given that,

x = y²

x = y³

so, y² = y³

thus, y = 0, y = 1

now, we can set up integral for volume:

V=  [tex]\int\limits^1_0 {x} \, dx \int\limits^{y_{2}}_{y_{3}} {9x + 5y^2} \, dx[/tex]

Firstly, we will solve innermost integral:

V = [tex]\int\limits^{y_{2}}_{y_{3}} {9x + 5y^2} \, dx[/tex]

V = [tex]\int\limits^{y_{2}}_{y_{3}} {5y^2} \, dx + \int\limits^{y_{2}}_{y_{3}} {9x } \, dx[/tex]

V = 5y⁴ - 5y⁵ + 9 (y⁴/2 - y⁶/2)

V = -9/2 y⁶ - 5y⁵ + 19y⁴/2

now, we can find outermost integral:

= [tex]\int\limits^1_0 {-9/2y^6 - 5y^5 + 19y^4/2} \, dx[/tex]

= -9/14 - 5/6 + 19/10

=  89/210

Thus, the volume of the solid under the surface z = 9x + 5y² and above the region bounded by x = y² and x = y³ is: 89/210

f(x) = √(x)

Part III.

f(g(x)) = f(3x-4) = √(3x-4)

In Part I, the function F(x) is the square root of 3x-4. Therefore, g(x) is the expression inside the square root: g(x) = 3x-4.

In Part II, the function f(x) is the square root operation applied to its argument, so f(x) = √(x).

Finally, in Part III, we substitute g(x) into f(x) to obtain f(g(x)) = f(3x-4) = √3x-4), which is equal to F(x)

So,

f(g(x))= √(3x-4) = F(x)

Now we have 69. 22 can go into 69. As you did it, 22 can only go in three times. So we add the 3 to the top and put 66 on the bottom, as 22*6 = 66. Now, we subtract 69 and 66. This gives us 3. Now, we bring down the 1. So instead of 3 as you have it, it'd be 31. 22 can go into 31 one time. So, we put our 1 up top and put our 22 on the bottom, as 22*1 = 22. Then, we finish by subtracting 31 from 22, which equals 9.

The given statement, "in 2014 the number of mobile phones was greater than the planet's population" is true (T) because there were 5.8 billion mobile users globally, about 80% of the world's population, and they each had 1.5 devices.

In 2014, there were more mobile phones than there were people on the planet. This is because many people own more than one phone, either as a personal and work phone or as a backup device. Additionally, the rise of low-cost mobile devices in emerging markets, where many people were purchasing their first phones, contributed to the high number of mobile phones relative to the population.

This trend has continued, with the number of mobile phones in the world continuing to grow, outpacing population growth and driving down the cost of devices so that even more people have access to them.

r² = 16

r = 4

Now that we know the radius, we can find the slant height. The slant height is 4 times the radius, so:

4 * r = 4 * 4 = 16

The lateral area of a cone is equal to π times the slant height times the radius of the base, so:

lateral area = π * r * slant height = π * 4 * 16 = 128π

A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math. f = {(a,b)| for all a ∈ A, b ∈ B}.

1) A relation is said to be a function if every element of set A has one and only one image in set B.

2) A function is a relation from a non-empty set B such that the domain of a function is A and no two distinct ordered pairs in f have the same first element.

A function from A → B and (a,b) ∈ f, then f(a) = b, where 'b' is the image of 'a' under 'f' and 'a' is the preimage of 'b' under 'f'.

If there exists a function f: A → B, the set A is called the domain of the function f, and the set B is called its co-domain.
