Hello :

the nth term ( general term  of an arithmetic sequence is :

An =A1+(n-1)d   ....a common difference is : d , A1 : the first terme
A1 = 5    and : d = 1 - 5 = - 4    n = 21
A21 = 5 + (21 -1)(-4)
A21 = 5 - 80 = -75

Find the annual percentage yield (APY) in the following situation,
netineya [11]

Answer:

3.95%

Step-by-step explanation:

An interest-bearing account paying a stated nominal or annual interest rate of 3.880% compounded monthly, would translate to an Annual Percentage Yield (APY) or Effective Annual Rate (EAR) of 3.95%. This means that $100.00 will grow to $103.95 ($103.95 rounded) after one year.

The spinner below is spun three times, find all possible outcomes. the spinner has 12 numbers
Simora [160]

For the spinner with 3 sectors, the total number of outcomes for 3 spins is 27.

<h3></h3><h3>What is the combination?</h3>

A combination is a mathematical technique that determines the number of possible arrangements.

Let's we have to define

A, B, and C, as the regions in the spinner.

So, we spin it 3 times, and for each of these times there are 3 outcomes, so the outcomes will be of the form:

The outcome of spin 1, the outcome of spin 2, outcome of spin 3.

The total number of  different outcomes will be:

3^3 = 27

Kevin is observing the population of the fish he put into a pond. He built a pond and populated it with 500 fish. The population
laila [671]

Here we will use exponential form, which is

y = y_{0} e^{kt}

Initial value, y0 = 500

Double of 500 = 1000

1000 = 500e^{k*1}

2 = e^k

k= ln (2)

Required equation is

y=500e^{x ln2} \\ y= 500 (2)^x
