lations Write the first four terms of the sequence {an} defined by the following recurrence relations. Enumerated sequences Several terms of a sequence {an}n=1 infinity are given. Find the next two terms of the sequence. Find a recurrence relation that generates the sequence (supply the initial value of the index and the first term of the sequence). Find an explicit formula for the general nth term of the sequence. 17. {1. 1/2, 1/4, 1/8, 1/16,....} 19. {1,2,4,8,16,...} 21. {1.3,9,27,81,...}

They estimate that their current (older) fridge, which they got for free, costs them about $17 a month in electricity charges to
Eddi Din [679]

Step-by-step explanation:

Step one:

given

current (older) fridge

electricity charges= $17 monthly

maintenance costs= $220

let the number of months be x

and the total cost be yo

the expression for the cost for the old fridge is

yo=220+17x---------1

New  fridge

electricity charges= $6 monthly

costs=  $1,050

let the number of months be x

and the total cost be yn

the expression for the cost for the old fridge is

yn= 1050+6x---------2

Hence the system of equation for the situation is

yo=220+17x---------1

yn= 1050+6x---------2

Step two

for 10 years there are 12*10= 120 months

put x= 120 in both expressions and compare the total

yo=220+17(120)---------1

yo=220+2040

yo=$2,260

yn= 1050+6(120)---------2

yn=1050+720

yn=$1770

<u><em>Based on the analysis it will be less expensive to get the new fridge, hence buying the new fridge is worth it.</em></u>

How do I solve for y:<br> x²y² = 12/z²
Vika [28.1K]

Answer:

Y=Srt(12xs^2/z^2)

Step-by-step explanation:

Firstly

We multiply both sides with 1/x^2

We get

Y^2=12/z^2*1/x^2

Y^2=12x^2/z^2

Next: introduce a srt root

We have

Y=srt(12x^2/z^2)
