The 100th line segment by using the nth term of a sequence is equal to 20200.

A sequence can be defined as a series of real and natural numbers in which each term or list of elements are ordered in a particular order and repetitions are allowed.

Next, we would determine the differences between the terms in this sequence until all the differences are the same:

12 - 4 = 8

24 - 12 = 12

40 - 24 = 16

12 - 8 = 4

16 - 12 = 4

Since the differences are the same, the sequence is a quadratic function and it contains an n² term. Also, the coefficient of n² is one-half of the equal difference. This ultimately implies that, the coefficient of n² is equal to 2.

In order to determine the nth term of this sequence, we would develop a table to model increment:

n                    1       2       3      4

2n²                2       8      18    32

Operation    +2     +4     +6    +8

Sequence     4       12     24   40

By critically observing the table above, we can logically deduce that the nth term of this sequence is given by:

aₙ = 2n² + 2n

a₁₀₀ = 2(100)² + 2(100)

a₁₀₀ = 2(10000) + 2(100)

a₁₀₀ = 20000 + 200

a₁₀₀ = 20200.

The number of employees decreased by 18 percent

The formular for percent decrease is

old value-new value/old value × 100

old value= 1500

new value= 1230

1500-1230/1500 × 100

= 270/1500 × 100

= 0.18 × 100

= 18

Answer:

8 boys.

Step-by-step explanation:

Lets say b is the number of boys and g is the number of girls.

We know that:

23 = b + g

g = b + 7

So then lets solve for b:

23 = b + g

23 = b + ( b + 7)

Simplify.

23 = 2b + 7

Subtract 7 from both sides to isolate the b.

16 = 2b

Divide both sides by 2.

8 = b

So there are 8 boys in the class.

We can check our work by substituting the value of b into our equation.

23 = b + ( b + 7)

23 = 8 + ( 8 + 7 )

23 = 8 + 15

23 = 23

So therefore our answer is correct.

Using the numeric value of functions, it is found that:

To find the numeric value of a function, we replace each instance of the variable by the desired value.

The formula for the velocity is given as follows:

[tex]v = 8\sqrt{h}[/tex]

In which h is the height.

For this problem, we have that the height is of h = 9.8, hence:

v = 8sqrt(9.8) = 25 feet per second.

The holder was running at a rate of 25 feet per second.

Then, in two seconds, the distance is given as follows:

d = 25 x 2 = 50 feet.

The pole vaulter will run 50 feet in 2 seconds.

On 50th day she needs to buy new bags of rice.

A sequence is defined as an arrangement of numbers in a particular order.

Sequence: 0.4, 0.8, 1.2, 1.6,......20

a=0.4, d=0.4, a_n= 20

Now,

we have to find in how many days 20 pounds rice will ends

So,

a_n= a + (n-1 )d

20 = 0.4 + (n-1) * 0.4

19.6 = (n-1)0.4

19.6/0.4= n-1

49 = n-1

n= 50

Hence, on 50th day she needs to buy new bags of rice.

The cost of the washer based on the total cost of $1,800 of all three items is $442.86

How do represent the cost of the washer?

If we assume that the cost of the washer is x, based on that we can determine the cost of the refrigerator and the dryer while deriving from the cost of the washer as denoted below:

cost of washer=x

The cost of the refrigerator is $250 more than the cost of washer i.e. x+250

cost of dryer=0.5*x

cost of dryer=0.5x

total cost=x+x+250+0.5x

total cost=3.5x+250

total amount spent=1800

1800=3.5x+250

1800-250=3.5x

Answer:

The answer will be A.

Answer:

  (a) height: 44.5 m

  (b) shadow: 71.2 m

Step-by-step explanation:

You want building height and shadow length for angles of elevation 56° and 32°, given the shadow is 30 m when elevation is 56°.

The building height and shadow length are the sides opposite and adjacent (respectively) to the elevation angle in the right triangle that models the geometry. The trig function that relates these sides to the angle is the tangent function:

  Tangent = Opposite/Adjacent

(a) building height

Using the tangent relation, we have ...

  tan(56°) = (height)/(30 m)

  height = (30 m)(tan(56°)) ≈ 44.4768 m

The height of the building is about 44.5 meters.

(b) shadow length

Using the same relation with the building height known, we have ...

  tan(32°) = (44.4768 m)/(shadow)

  shadow = (44.4768 m)/tan(32°) ≈ 71.1778 m

The length of the shadow at an angle of 32° is about 71.2 m.

[tex]2a^2b*(3a^2-5ab-3b^2)[/tex]

Step-by-step explanation:

Attempt factorization by grouping

(((6•(a^4))•b)-((10•(a^3))•(b^2)))-((2•3a^2)•b^3)

(((6•(a^4))•b)-((2•5a^3)•b^2))-(2•3a^2b^3)

(((2•3a^4) • b) -  (2•5a^3b^2)) -  (2•3a^2b^3)

6a^4b - 10a^3b^2 - 6a^2b^3  =  2a^2b • (3a^2 - 5ab - 3b^2)

Pull out the leading term and put it with the original equation

= 2a^2b • (3a^2 - 5ab - 3b^2)

This would be one of the quicker ways to factor this equation.

2: Set up a table for the remaining numbers.

3: Transfer the decimals from your math problem into the table.

4: Compare the digits in the tenths column of the table

5: Compare the hundredths column (2 to the right of the decimal point).

6: Examine the digits in the thousandths column.

7: Order the numbers from least to greatest.

- 27.08 - 2nd because 0 is the least/lower number than 8 (tenths value)

- 27.88 - 4th because there are two numbers after the decimal which are greater than the others (tenths & hundredths value)

- 27.8 - 3rd because there is only one number after the decimal (tenths value)

- 26.78 - 1st because 6 is the least number than 7 (tens value)

The monthly finance charge for the credit card transaction is $51.70.

We need to calculate the monthly finance charge for the given credit card transaction.

Credit card transaction means the purchase of goods or obtaining of services or cash against the use of the Credit Card, the Card number or in any manner authorised by the Cardholder for debit to the Credit Card Account or utilising of any services made available to the Cardholder by the Bank from time to time in respect.

Given that, $3,000 balance, 21% rate, 150 payments, average daily method

The particular month in question is 30 days long.

Your balance at the start of the month is $3,000.

Annual interest rate = 21%.

Payment = $150.00

When the payment is made in the month, it reflects on the tax amount you pay on both the average daily balance.

The average daily balance is $3000 from day 1 until day 10 (10 days)

The average daily balance is $2850 from day 11 until day 30 (20 days)

Average daily balance for the month = 10 × 3000 + 20 × 2850

= 87000 / 30

= $2900

Interest charge for the month = (0.21 × 2900× 30) / 365

The interest charge for the month = $50.05 rounded to the nearest penny

The average daily balance is $3000 from day 1 until day 29 (29 days)

The average daily balance is $2850 from day 30 until day 30 (1 day)

Average daily balance for the month = 3000 × 29 + 1 × 2850

= 89850 / 30

= $2995

Interest charge for the month = (0.21 × 2995 × 30) / 365

=51.6945≈$51.70

Therefore, the monthly finance charge for the credit card transaction is $51.70.
