Spacecraft exploring the outer planets need reliable data transmission. however, the acknowledgments would take hours to arrive.

this makes an ack-based reliability approach unattractive. can you think of another way to provide more reliable data transmission to spacecraft without using acknowledgments?

<span>Use forward error correction (FEC) to perform the data transmissions. FEC is a method where you transmit the data that's been encoded with an error correction code (ECC). This adds redundancy to the data transmission which allows for some errors to be corrected upon reception without having to rely upon the sender having to send the data again. One example of an ECC is the Reed Solomon error correction code. That code is used in many different applications where retransmission of corrupted data isn't practical, such as disk sectors in hard disk drives, data encoded on optical media such as DVDs, CDs, or Blu-Ray discs. It is also frequently used for communications from satellites.</span>

How many years are required for an investment to double in value if it is appreciating at the rate of 9​% compounded​ continuous
Vesna [10]

Answer:

time required is 7.70 years

Explanation:

given data

interest rate = 9%

solution

we know with the compounded​ continuously rate r and time t amount is

A(t) = A(o) e^{rt}     .................1

and we have given amount is double so

A(t) = 2 A(o)

so from equation 1 put the value and we get here

2 A(o) = A(o) e^{rt}

ln(2) = 0.09 t

solve it we get time

time t = 7.70 years

so time required is 7.70 years

Semmy [17]

Answer:

discount on bonds payable 18,383,020.48 debit

other comprehensive income 18,383,020.48 credit

--to adjust Bonds at 12/31/2021 market value --

other comprehensive income  4.739.000‬ debit

    discount on bonds payable   4.739.000‬ credit

--to adjust Bonds at 12/31/2022 market value --

Explanation:

We solve for the book value at year-end using effective rate

<u>First year:</u>

<u>First payment</u>

830,000,000 x 5.5% = 45,650,000

767,557,868  x 6.0% = 46,053,472.08

Amortization              403,472.08

<u>Second Payment</u>

830,000,000 x 5.5% =                         45,650,000

(767,557,868 + 403,472.08)  x 6.0% = 46,077,680.4

Amortization               427680.4

Carrying value at year-end

767,557,868 + 403,472.08 + 427,680.40 = 768,389,020.48

We need to recognize a deferred gain for the difference between these and the 750,000,000 market value at December 31th

which is $ 18,383,020.48 as these as not been realized it will be part of other comprehensive income

We will increase the discount to adjust the bonds payable account net balance.

<u>Second year:</u>

We repeat the process

<em>First Payment:</em>

830,000,000 x 5.5% = 45,650,000

Interest expense 750,000,000 x 6% = 45,000,000

Amortization  650000

Carrying value 750,000,000 + 650,000 = 750,650,000

<em>Second Payment:</em>

830,000,000 x 5.5% = 45,650,000

750,650,000 x 6% = 45,039,000

Amortization 611000

Carrying Value 750,650,000 + 611,000 = 751,261,000

Wer now compare this with the 756,000,000

as now the debt of the company has increased we are going to decrease the discounttand recognize a deferred loss through other comprehensive income as it wasn't realized

756,000,000 - 751,261,000 = 4.739.000‬
