Answer:

The  recursive formula for the given sequence

                 t_{n}=  (2)^{n+2}

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given sequence is 8 , 16, 32, 64 ,.....

First term is   a = 8

common ratio   r = \frac{16}{8} =2

                       r = \frac{32}{16} =2

                      r = \frac{64}{32} =2   and so on..

Given sequence of the common ratio 'r' is equal

The n^{th} term of the sequence

                   t_{n} = a r^{n-1}

                   t_{n}= 8 (2)^{n-1}

                   t_{n}=  (2)^{(3+n-1)}

                  t_{n}=  (2)^{n+2}

This is  recursive formula for the given sequence

                 t_{n}=  (2)^{n+2}

<u><em>Verification</em></u>:-

           t_{n}=  (2)^{n+2}

put n=1   ⇒ t₁ = 8

put n=2   ⇒ t₂ = 16

put n=3   ⇒ t₃ = 32

put n=4   ⇒ t₄= 64    

and so on..

The sequence  8 ,16 , 32 , 64 ....

Jake got his first job in 2010. In that year, the government took out 7.45% of each income for Social Security and Medicare, unt
DENIUS [597]

Jake's Social Security and Medicare for the year 2010 is $2,334.83

What threshold of income does 7.45% as Social Security and Medicare?

The threshold in this case refers to a range of income that would be charged to Social Security and Medicare at  the rate of 7.45%, in essence, it is the income of $0 to $51,300, since Jake's income falls within the range, his Social Security and Medicare payment would be 7.45% of his income .

Social Security and Medicare payment=rate*Jake's income

rate=7.45%

Jake's income= $31,340

Social Security and Medicare payment=7.45%*$31,340

Social Security and Medicare payment=$2,334.83

The amount that Jake would have paid out of his income of $31,340 as Social Security and Medicare in the tax year of 2010 is $2,334.83.

The fact that Jake's income did not exceed the initial threshold of $51,300 means that the higher rate of Social Security and Medicare payment would not apply in this case.

Sphinxa [80]

Answer:

All payments will be made at the end of the year by using the present value of inflows

Step-by-step explanation:

Present Value Of Inflows = Cash Inflow × Present Value Of Discounting Factor (Rate%,Time Period)

Present Value Of Inflows = 15000/1.037 + 25000/1.037^{2} + 40000/1.037^{3} + 60000/1.037^{4}

Present Value Of Inflows = 125466.3

2. y = 3x + c

3. 1) non-proportional

2) can be proportional if c = 0

Step-by-step explanation:

1. What is the equation of a line that has a slope of ⅔ and a y-intercept of -3?
