We have proved below that d( k+1) is only true when d(k) is true , also d(1) should also be true using Mathematical Induction.

Mathematical Induction : For each and every natural number n, mathematical induction is a method of demonstrating a statement, theorem, or formula that is presumed to be true.

It is given that the statement is true for n = k

Explanation:

According to the principle of Mathematical Induction,

Let d(n) be a statement involving Natural Number n such that

d(1) is true

d(m) is true

d(m+1) is true

So ,  the statement d(n) is true for all the n natural numbers.

According to the second principle of Mathematical Induction

Let d(n) be a statement involving Natural number n such that

d(1) is true

d(m) is true when d(n) is true for all n where 1 ≤ n ≤m .

Then the statement d(n) is true for all the values of n ( natural number)

Therefore , we have proved below that d( k+1) is only true when d(k) is true , also d(1) should also be true using Mathematical Induction.

The expression that represents the maximum number of attendees at Jets, Dolphins, and Patriots home games during the season is 82,500 j + 65,326 d + 66829 p.

We are given that:

Team                        Number of seats

Jets                                 82,500

Dolphins                         65,326

Patriots                           66,829

The number of attendees at the jets home games = j

The number of attendees at the Dolphins home games = d

The number of attendees at the Patriots home games = p

So, the maximum number of attendees can be written by the expression:

82,500 j + 65,326 d + 66829 p.

Therefore, we get that, the expression that represents the maximum number of attendees at Jets, Dolphins, and Patriots home games during the season is 82,500 j + 65,326 d + 66829 p.

Answer:

  x = 70°

  y = 35°

Step-by-step explanation:

Given one angle of a triangle is 75° and the other two are 'x' and 'y', you want to find the possible values of 'x' and 'y' when x = 2y.

The angle sum theorem and the given relation give rise to two equations:

  75 +x +y = 180

  x = 2y

Using the second equation to substitute for x in the first equation, we have ...

  75 +(2y) +y = 180

  3y = 105 . . . . . . . . . subtract 75 and simplify

  y = 105/3 = 35

  x = 2y = 2(35) = 70

The measures of angles x and y are 70° and 35°, respectively.

The percentage of increase in the price of  the car is 32%

Percentage increase means adding the given percentage of  value to the original value.

To calculate this percentage increase:

            =  100{( final value - initial value )/initial value}

Given that last month online price of powered ride-on car was $250

and this month this cost is $330

Initial value = $250

Final value  = $330

Percentage increase =  100{ ( 330 -250 )/250} =100*0.32 = 32%

This the percentage increase in the price of the powered ride-on car is 32%

What does "speed" mean in mathematics?

Running time of cassettes

at standard speed = 4 hr

at standard speed = 4 hr

given the 1/4 part of tape is recorded at standard speed, 1/3 at long-play speed , 5/12 at super long-play speed,

so the running time of standard speed = 1/4 * 1 = 1/4

at long play speed

If x and y are directly proportional and we take a third of x we also have to take a third of y, which means we have to multiply y by 1/3.

Two quantities when they are in direct proportion increase or decrease by the same constant and when they are inversely proportional if one quantity increases the other quantity decreases.

We know when two quantities are directly proportional we can relate them by proportionality as x ∝ y or x = ky.

∴ if we take 1/3 of x to maintain the equality we have to multiply y also by 1/3.

In mathematical terms, Number Line is defined:

A visual representation of numbers(whole, natural, decimal, integers, fraction) using a horizontal line drawn straight with equal spacing divisions that represent each number.

Numbers are marked at equal intervals ans it is used to illustrate basic numeric operators. There is no limit to a number line, which means that it expands to positive and negative infinity. The middle of the number line is represented by zero, and on the right side are all the positive values up to the positive infinity. The same for the left side where are all the negative values are listed up to the negative infinity.

Now what is given to us in the question statement are a bunch of decimals. We know decimal numbers are considered real numbers and thus can easily be plotted on the number line. In order to plot the decimal numbers, we need to mark the intervals with decimals values.

The image attached below gives a clear representation of how the numbers will be plotted.

Values closer to 0, like 0.75, and 0.705, will be plotted more towards the right, and those away from zero, like 0.44, 0.279 will be plotted more towards the left of zero.

To solve the system of equations using elimination, we will equate any one variable. In this case, we will be equating variable y.

Rewriting the equations -

-6x - 6y = −42 : equation 1

-x + 2y = 8 : equation 2

Multiplying equation 2 with 3

-3x + 6y = 24 : equation 3

Adding equation 1 and equation 3 to solve the given system of equations

-6x - 6y = −42

3x + 6y = 24

We get the answer :

-3x = -18

Negative sign will be cancelled and performing division

x = 6

Keep the value of x in equation 2

-6 + 2y = 8

(2x^(4)y^(-3))

= 2x^4/ y^3.

a) The line segment PQ has a length of √85 (approx. 9.219).

b) The coordinates of the midpoint of the line segment PQ is (4, 0.5).

Herein we find a line segment whose endpoints are known: P(x, y) = (3, 5), Q(x, y) = (5, - 4), and we are asked to determine the length of the line segment and the coordinates of the midpoint as well. a) First, we determine the vector between the points P and Q by sum of vectors:

PQ = Q(x, y) - P(x, y)

PQ = (5, - 4) - (3, 5)

PQ = (2, - 9)

And its magnitude is determined by using the Pythagorean theorem:

PQ = √[2² + (- 9)²]

PQ = √85

b) The coordinates of the midpoint is found by using the following formula:

M(x, y) = 0.5 · P(x, y) + 0.5 · Q(x, y)

M(x, y) = 0.5 · (3, 5) + 0.5 · (5, - 4)

M(x, y) = (1.5, 2.5) + (2.5, - 2)

Answer: Aiza have left from her lifeguarding job = $ 700

Step-by-step explanation:

Given that,

Aiza made $55 a day lifeguarding in the summer.

She worked six days a week for five weeks.

For two weeks of the summer she went on vacation.

She spent approximately $68 a day each for two weeks.

Aiza earning per day = $55

Aiza worked for six days in a week.

Aiza worked for five weeks.

Total earning for weeks

                          = $ 55(6)

                          = $ 330 / week

Total earning for 5 weeks

                           = $ 330(5)

                           = $ 1650

Aiza spent per day for vacation = $ 68

Aiza was an vacation for two weeks.

Total expenditure for two weeks,

Number of days in each week = 7 days

                                                   = 2(7)($ 68)

                                                   = $ 952

Aiza have left with = Total earning - Total expenditure

                               = $ 1650 - $ 952

                               = $ 700

His final payment will be $271.66464 at the end of the third year.

The term "compound interest" refers to interest that is added back to the principal amount during each compounding period.

Compound interest is calculated using the formula

A = P(1+r )ⁿ,  where

P = principal balance,

r = interest rate,

n =  number of periods.

Given that a man borrows $760 at 4% and of the first year he pays back $270.

Amount owned by him at the end of the first year after repaying $270 =  (1+4%)760 - 270

= 1.04×760 - 270

= $520.4

Amount owned by him at the end of the second year after repaying $280 =  (1+4%)520.4 - 280

= 1.04×520.4 - 280

= 541.216 - 280

= $261.216

Let his final payment be x.

So, the amount owned by him at the end of the third year will be 0.

⇒ (1+4%)261.216 - x = 0

⇒ 1.04×261.216 - x = 0

⇒ 271.66464 = x

Therefore, his final payment will be $271.66464.
