Which of the following functions represents an arithmetic sequence?

1. f(n)=3n^2−4
2.f(n)=3n−4
3.f(n)=3^n−4
4.f(n)=3^n−4^n

Answers

Answer 1

Answer:

Option (2)

Step-by-step explanation:

Explicit formula of an arithmetic sequence is always in the linear form.

A(n) = a + (n - 1)d

Here A(n) = nth term of the sequence

a = first term

n = number of term

d = common difference

Formula doesn't have the terms with the exponent.

Therefore, from the given options, expression that represents an arithmetic sequence will be,

f(n) = 3n - 4

Option (2) will be the correct option.

In order to help her save money for college, Latasha's grandparents deposited $10,000 into a savings account five years ago. Latasha has not made any withdrawals or deposits since then. The interest rate on the savings account is 3.75% each year.
Using simple interest, how much interest has accrued in Latasha's savings account?

What is the total amount in Latasha's savings account?

Answers

Answer:

$11,875

Step-by-step explanation:

3.75×5 = 18.75%

[tex]\frac{18.75}{100}[/tex]×10000 = 18.75 × 100 = 1875 (we cut the zeros so that it will be easier to solve the equation)

10,000 + 1875 = $11,875 after 5 years

$1875 has accrued in Latasha's savings account

$11,875 is the total amount in Latasha's savings account after 5 years
