Divide 8 by 9

8 / 9 = 0.888

0.88 is greater than 0.60 so it is not between 0.45 - 0.60

Answer: it will take 14 years

Step-by-step explanation:

A savings account is started with an initial deposit of $600. This means that the principal P is

P = 600

It was compounded annually. This means that it was compounded once in a year. Therefore,

n = 1

The rate at which the principal was compounded is 2.1%. So

r = 2.1/100 = 0.021

The duration of time that for which the money stayed in the account is t years. So

Time = t

The formula for compound interest is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years. Therefore,

a) the equation to represent the amount of money in the account as a function of time in years would be

A = 600 (1+0.021/1)^1×t

A = 600 (1.021)^t

b) the amount of time it takes for the account balance to reach $800 would be

800 = 600 (1.021)^t

Dividing both sides of the equation by 600, it becomes

1.33 = (1.021)^t

t = 14

In an arithmetic​ sequence, the nth term an is given by the formula An=a1+(n−1)d​, where a1is the first term and d is the common
Olin [163]

Answer: 433

Step-by-step explanation:

The given sequence : 19​,42​,65​,88​,...

We can see that the terms ha common difference as :-

42-19=23\\65-42=23\\88-65=23

Thus, its an Arithmetic progression with common difference (d)=23

The formula to find the nth term is :-

a_n=a_1+(n-1)d

Now, the 19th term of the given sequence :-

a_{19}=19+(19-1)(23)\\\\=19+(18)(23)\\\\=19+414=433

Hence, the 19th term of 19​,42​,65​,88​,... is 433.
