VladimirAG [237]

Answer:

The amount of money you will receive is $927.419

Step-by-step explanation:

Consider the provided information.

A youth group has a yard sale to raise money for a charity. The group earns $800 but decides to put its money in the bank for a while.

We need to calculate the amount of money if hot bank pays an interest rate of 3% compounded annually, and the youth group leaves the money in for 5 years.

Future value can be calculated as:

$FV=PV(1+r)^n$

Substitute PV=800, r=0.03 and n=5 in above equation.

$800(1+0.03)^5$

$800(1.03)^5=927.419$

Hence, the amount of money you will receive is $927.419

640, 160, 40, 10, ...

WARRIOR [948]

Answer:

Option 3 and 5 are correct

Step-by-step explanation:

We have given a geometric series 640,160,40,10....

Common ratio of geometric series is $r=\frac{a_2}{a_1}$

$r=\frac{160}{640}=\frac{1}{4}$

Here our common ratio is less than zero

It will show the graph of exponential decay

Hence, option 5 is correct.

The general term of geometric series is $a_n=a\cdotr^(n-1)$

Domain will be all natural numbers since, geometric series take only natural numbers.

Here, values of "n" is domain

Hence, option 3 is correct.

Range can be any positive real numbers not only natural number

Range is the value of $a_n$

Hence, option 4 is discarded.

Graph can not be linear of a geometric series being exponential

Hence, option 2 is discarded.

Option 1 is discarded because it is exponential decay function so it can not be exponential growth.

Therefore, Option 3 and 5 are correct.
