What is proof by induction?

For each and every natural number n, a statement, theorem, or formula can be proved using the mathematical induction technique. By generalizing this into the "Principle of Mathematical Induction," which we would utilize to demonstrate any mathematical assertion.

We are given a statement 1+3+5+. +(2n-1)=n^2

Now first let us prove the statement for n=1 where n is the number of terms

On the left hand side = 1

And on the right hand side = 1^2 = 1

Hence the statement is proved for n =1

Now let us prove the statement for n= k

Therefore we have 1+3+5+....+k=k^2

Now let us prove the statement for n= k+1

Hence we have

1+3+5+....+k+(k+1)=

k^1+k+1

= (k+1)^2

Hence proved

Therefore we prove the following step using proof by induction

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, Mellisa has options to choose from 3 different snacks,

N(GB) = 4, N(C) = 3, and N(FS) = 5.

So, The sample space N(S) = N(GB) + N(C) + N(FS).

N(S) = 12.

The probability of choosing a fruit snack is,

P(FS)

= N(FS)/N(S).

= 5/12.

Given, She puts it back so replaced and hence the events are independent.

So, The probability of choosing a granola P(GB) = N(GB)/N(S).

= 4/12.

The height of the tail post is 13.74 m.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that, after travelling 11.45 metres from her school, she lays a flat mirror on the ground in the center, with an x drawn on it. When she can clearly see the top of the goalpost depicted in the x.

She moves 1.25 metres to the other side of the mirror. Her spouse calculates that there are 1.15 metres between her eyes and the earth.

Suppose the height of the tail post is x,

The geometric relation is,

1.5/1.25 = x/11.45

Apply cross multiplication

1.5×11.45=1.25x

17.175=1.25x

Divide both sides by 1.25

x=13.74

Hence,  if she moves 1.25 metres to the other side of the mirror. Her spouse calculates that there are 1.25 metres between her eyes and the earth. The height of the tail post is 13.74 m.

After solving the equation we know ABCD is a parallelogram.

What is parallelogram?

A parallelogram is a two-dimensional shape with four straight sides. All of the sides are equal in length and the opposite sides are parallel. Additionally, opposite angles are also equal. The shape is called a parallelogram because parallel lines are present on either side. Parallelograms can come in many different forms, such as rectangles and rhombuses. The properties of a parallelogram include the fact that the diagonal line that divides the parallelogram into two halves bisects the angles. Additionally, the cross product of the two diagonals is equal to the area of the parallelogram. Parallelograms are used in a variety of areas, including architecture, engineering, and mathematics. Depending on the application, parallelograms can be used to construct a variety of shapes, such as circles and ellipses.

Given: A (2,5), B (7,6), C (6,2), D (1,1)

AB ⇒ A (2,5), B (7,6) = [tex]\sqrt{(x_{2}-x_{1} ) ^{2} +(y_{2}-y_{1} )^{2} }[/tex]

The complex number (25 + 22i)² in simplest form a + ib is 141 + 1100i

A complex number is a number in the form z = x + iy where

To find the complex number (25 + 22i)² in the form a + ib, we proceed as follws.

(25 + 22i)² = (25 + 22i)((25 + 22i)

Expanding the brackets, we have that

(25 + 22i)² = (25 + 22i)((25 + 22i)

(25 + 22i)² = [25 × 25 + 25 × 22i + 25 × 21 + (22i)²]

(25 + 22i)² = [625 + 550i + 550i + 484i²]

(25 + 22i)² = [625 + 550i + 550i + 484 × (-1)] Since i² = -1

(25 + 22i)² = [625 + 550i + 550i - 484]

Collecting like terms, we have that

(25 + 22i)² = [625 - 484 + 550i + 550i]

(25 + 22i)² = 141 + 1100i

So, (25 + 22i)² = 141 + 1100i

Answer: I mean- can you found it out yourself by studying. There's your answer.

Step-by-step explanation:

just study not cheat.

The equation of the parabola that has a force at (3, 9) and directrix at y = -5 will be x² - 6x + 65 = 28y.

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

Let (x, y) be the locus point. Then the equation is given as,

(x - 3)² + (y - 9)² = (y - 5)²

Simplify the equation, then we have

(x - 3)² + (y - 9)² = (y - 5)²

x² - 6x + 9 + y² - 18y + 81 = y² + 10y + 25

x² - 6x + 65 = 28y

The equation of the parabola will be x² - 6x + 65 = 28y.

Ordered pair (3, 1) and (3, 2) causes the relation to not be a function; The same x-value has different y-values.

How do you find out if a set of ordered pairs is a function or not?

For a set of ordered pairs to be a function, there must not be any two points that have the same first elements. This means that, the

x-coordinates must not repeat for any two given points.

According to the given question:

Given ordered pairs of a relation are

(0, 0.5), (0.5, 1), (3, 1), (1, 6), (3, 2)

Domain set of the relation= {0, 0.5, 1, 3}

Co-Domain set of the relation = {0.5, 1, 2, 6}

Clearly the image of the x-coordinate 3 is not unique.

Hence, (3, 1) and (3, 2); The same x-value has different y-values.

The inequality for the given situation is 25,000x-20,000,000≤5,000,000 and the solution for the obtained inequality is x≤1000.

Given that, it costs chevy $20,000,000 to develop and market a new model of cars.

The profit or gain is equal to the selling price minus the cost price. Loss is equal to the cost price minus the selling price.

Let the number of cars sold be x.

So, selling price of cars is $25,000x

Profit =Selling price-Cost price

⇒ 25,000x-20,000,000≤5,000,000

Solve the inequality

Add 20,000,000 on both the sides of an inequality, we get

25,000x≤25,000,000

⇒ x≤25,000,000/25,000

False. The hour property of the datetime structure stores the hour as an integer between 0 and 23.

To support varied needs, three different property types are available:

1. Date — A day of the Gregorian calendar, without reference to a time zone or locale. The unit is a whole day, such as July 23, 2006.

2. Time of Day — A time of day, without reference to a time zone or locale. The unit is seconds, such as 15 seconds after 1:25 P.M.

3. Date Time — A date and time, stored internally to the millisecond if available, in a known time zone. For example 15.452 seconds after midnight on July 23, 2006 in London, U. K.

When presented with a DateTime value, a corresponding date and a time-of-day (in a specified time zone) can be determined.

However, the converse is not usually true: when starting with a Date and a TimeofDay value, multiple differing but "correct" DateTime values can be constructed, depending on assumptions about time zone, Daylight Savings Time, and other considerations. For example, when the date is January 1 in London, it can be December 31 in New York.
