What is a Triangle?

Triangle ABC is the display style for a triangle with vertices A, B, and C.

In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces.

One of the internal angles of a right triangle (also known as a right-angled triangle) measures 90 degrees (a right angle). The hypotenuse, the triangle's longest side, is the side that faces the right angle. The triangle's other two sides are referred to as its legs, Right triangles follow the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the two legs of a right triangle (a2 + b2 = c2). Special right triangles have extra characteristics that simplify computations involving them. The 3-4-5 right triangle is one of the two most well-known.

The derivative of the function f(x) = Sin⁻¹(3x) is f'(x) = 3/√(1-9x²)  , the correct option is (c) .

In the question ,

a function is given as

f(x) = Sin⁻¹(3x) , we need to find the derivative .

we know that the derivative of Sin⁻¹(x) is equal to 1/√(1 - x²) .

So , on differentiating both sides with respect to "x" .

we get

f'(x) = d/dx (Sin⁻¹(3x))

= 1/√1-(3x)² ×  d/dx (3x)

= 1/√(1 - 9x²) × 3

On simplifying further ,

we get

= 3/√(1 - 9x²)

Therefore ,the derivative of the function is 3/√(1-9x²)  , the correct option is (c) .

5. The diagram shows a rectangular field ABCD has a path of uniform width around it. AB and BC are 6m and 4 m respectively. Given that area PQRS is twice the area of ABCD. Find the length of PQ and QR.​

Answers

Tthe length of PQ and QR.​ is 6 and 8 m

Area of rectangular field ABCD is = 4m x 6m = 24m2

Area of rectangular field PQRS (ABCD with uniform path) = (4 + x)(6 + x)

= 24 + 4x + 6x + x²

48 = 24 + 10x + x²

x² + 10x - 24 = 0

x² + 12x - 2x - 24

x(x + 12) - 2(x + 12)

(x - 2)(x + 12) = 0

x - 2 = 0

x = 2

PQ = 4 + 2 = 6

Ben starts walking along a path at 3 mi/h. One and a half hours after Ben leaves, his sister Amanda begins jogging along the same path at 6 mi/h. How long (in hours) will it be before Amanda catches up to Ben?

Answers

It would take Amanda 2.25 hours to catch up with Ben

Speed is the ratio of distance to time. It is given by:

Speed = distance/time

Given that Ben covers a distance d at time t, hence:

3 = d/t

d = 3t

Since Amanda leaves One and a half hours (1.5) after Ben leaves, hence Time = t - 1.5

5 = d/(t - 1.5)

d = 5t - 7.5

Since they catch up, hence:

3t = 5t - 7.5

2t = 7.5

t = 3.75 hours

Time for Amanda = t - 1.5 = 3.75 - 1.5 = 2.25 hours

Hence it would take Amanda 2.25 hours to catch up with Ben.

Write a quadratic function f whose zeros are 7 and -5.

Answers

Answer:

  f(x) = x² -2x -35

Step-by-step explanation:

You want a quadratic function that has zeros 7 and -5.

Factors

Each zero (p) gives rise to a factor (x-p). The zeros 7 and -5 mean the quadratic has factors (x-7) and (x-(-5)).

  f(x) = (x -7)(x +5)

  f(x) = x² -2x -35

Additional comment

You may notice that the coefficient of the linear term is the opposite of the sum of the zeros. The constant term is the product of the zeros. Knowing this, we can write the quadratic without any concern for the factors.

  sum: 7-5 = 2

  product: (7)(-5) = -35

To convert the above odd's expression to probability expression, we make use of the following equation

This is represented as

P = Odds/(Odds + 1)

Substitute the known values in the above equation

So, we have the following equation

P = (8/9)/(8/9 + 1)

Answer: x = -135.59

Step-by-step explanation:

20 = 0.694(x + 150)(2)

Step 1: Simplify both sides of the equation.

20 = 0.694 (x + 150)(2)

20 = 1.388x + 208.2 (use the distributive property)

20 = 1.388x + 208.2

Step 2: Flip the equation.

1.388x + 208.2 = 20

Step 3: Subtract 208.2 from both sides of the equation.

1.388x + 208.2 − 208.2 = 20 − 208.2

1.388x = −188.2

Step 4: Divide both sides by 1.388.

Subtraction of integers is used find the difference between two integers.

Repeated addition is called multiplication. Multiplication is used to find the product of two or more integers.

Division is the process in which the value of single unit can be calculated from the value of multiple unit

The number to be divided is known as dividend, the number by which the dividend is divided is the divisor, the result obtained is the quotient and the remaining part is the remainder.

There is a well known formula for division

Divisor x Quotient + Remainder = Dividend.

Here, addition, subtraction, multiplication and division of integers will be used

Total number of boys = 121

Total number of girls = 116

Total number of students = 121 + 116 = 237

Now,

The leader first makes groups of nine students each and then assigns any remaining students to make some groups of 10 students

So the group of 9 is to be made in such a way that on multiplying the number by 9, unit digit of 7 is obtained

So the number is 3 as 9 [tex]\times[/tex] 3 = 27
