Answer:Remember that the general formula of geometric sequence is 

where 

is the nth term

is the difference

is the place of the term in the sequence

Also, to find  we will use the formula: 

where 

is the current term in the sequence 

is the previous term 

a) Lets find the three first terms of our sequence to check what type of sequence we have:

We know for our problem that the initial value of the computer is $1250, so our first term is 1250. In other words .

To fin our second term , we are going to subtract 10% of the value to our original value:

and , so 

To find our third term  we are going to subtract yet again 10% to our current value:

and , so

Now that we have our sequence  lets check if we have a consistent  to prove we have a geometric sequence:

- with , and :

 

- with , and :

 

Look! our s are the same, so we can conclude that we have a geometric sequence.

b) To do this we just need to replece the values of our sequence in the general formula of a geometric sequence. We know from our previous point that  and . So lets replace those values in geometric sequence formula to find our explicit formula:

c) To find the value of the computer at the beginning of the 6th year, we just need to find the 6th therm in our geometric sequence:

We can conclude that the value of the computer at the beginning of the 6th year will be $738.1125

Step-by-step explanation:

i did some research i dont know if it helped out not but id appreciate brainliest if it did..... thank you.

A collection of quarters and nickels is worth $14.80. There are 88 coins in all.
ycow [4]
So the equaiton is

number of nickes=n
number of quarters=q

if you have 1 quarter then you have 25 cents so we will represent like this
25q

and nickles is 5n
14.50=1450 cents

so
25q+5n=1480
q+n=88
subtract q from both sides
n=88-q
subsitute into first equation
25q+5(88-q)=1480
25q+440-5q=1480
add like terms
20q+440=1480
subtract 440 from both sides
20q=1040
divide both sdies by 20
q=52
there were 52 quarters
25(52)+5n=1480
1300+5n=1480
subtract 1300 from both sides
5n=180
divide both sides by 5
n=36
there were 36 nickels


nickles=36
quarters=52

Given a≠±b and a^2−b^2/a+b =12, find a−b.
11Alexandr11 [23.1K]
\dfrac{a^2 - b^2}{a+b}  =  12

--------------------------------------------------
Factorise a² - b² :
--------------------------------------------------
\dfrac{(a+b)(a-b)}{a+b}  =  12

--------------------------------------------------
 Crossed out common factors, (x + a) :
--------------------------------------------------
a- b =  12

Need help with a math question
tatyana61 [14]

ANSWER

x = 71 \degree

EXPLANATION

The sum of the exterior angles of a polygon is 360°

The angles were given in terms of x.

We add all and equate to 360° to obtain.

x + (x - 6) + (x + 4) + (x + 2) + (x + 5) = 360 \degree

This implies that,

5x + 5 = 360

5x = 360 - 5

5x = 355

x  = \frac{355}{5}

x = 71 \degree
