s(5) =  \frac{243(1 - (  { \frac{1}{3})^{5}  )}  }{1 -  \frac{1}{3} }  =  \frac{242}{ \frac{2}{3} }  = 3 \times 121 = 363

A local diner purchased a jukebox for 9400. The business makes a down payment of 1000 and agrees to pay 36 payments of 275 per m
Rina8888 [55]

Answer:

Finance charge = $1500

Step-by-step explanation:

Cost price of  jukebox = $9400

Down payment made by a local diner = $1000

Balance amount to be paid = 9400 - 1000 = $8400

In order to pay the balance amount diner agreed upon the installments = $275 per month for 36 months

Total amount to be paid in 36 months = 275 × 36 = $9900

So extra payment done = Total balance amount - Amount paid in 36 installments

= 9900 - 8400

= $1500

Therefore, finance charge paid by the diner was $1500.

Find three solutions for this linear function and choose the correct graph by clicking on it. F -1(x) if F(x) = x + 3
algol13

Answer:

[1,2], [2,1], [3,0]

Step-by-step explanation:

To find F-1(x) if F(x)=x+3 we just need to put -x instead of x.

From our graph(attached) we multiply any three solutions by a -1:

F-1(x)\\\\#For \ x=1\\F-1(1)=-1+3=2\\\\#For \ x=2\\F-1(2)=-2+3=1\\\\#For \ x=3\\F-1(3)=-3+3=0

Hence, the 3 solutions are [1,2],[2,1],[3,0]

Apply the properties of exponents to verify that each statement is an identit.
Sholpan [36]

Answer and explanation :

We have given that the expression \frac{2^{n+1}}{3^n}=2\times (\frac{2}{3})^n

We have to prove L.H.S = R.H.S

Lets take L.H.S

\frac{2^{n+1}}{3^n}

It can be written as \frac{2^{n+1}}{3^n}=\frac{2^n\times 2^1}{3^n} ( As in multiplication exponent are added )

So \frac{2^n\times 2^1}{3^n}=(\frac{2}{3})^n\times 2 = R.H.S

Hence proved
