Each side of the square is exactly √39 ft long.

The length is an irrational number, so it can't be
written exactly with only digits.

Lisa invested $2500 in a bank account. The account has an annual interest rate of 3.5%. How much money will be in the account af
madreJ [45]

Answer:

A = $ 4188.38

Step-by-step explanation:

A= $2500

r = 3.5% = 0.035

t = 15years

n = 1

     A = P(1 + r)^t

        = 2500 ( 1 + 0.035)^{15}\\\\= 2500 (1.67535)\\\\= \$ 4188.38

Which table represents an arithmethic sequence?
Fiesta28 [93]

Table 3  represents an arithmetic sequence.

Solution:

To find which table represents an arithmetic sequence:

In arithmetic sequence difference of each term is equal.

d=a_n-a_{n-1}

Table 1:

d=a_2-a_1

  = –12 – (–6)

d = –6

d=a_3-a_2

  = –24 – (–12)

d = –12

Here differences are not equal.

So table 1 not represents an arithmetic sequence.

Table 2:

d=a_2-a_1

  = 9 – 7

d = 2

d=a_3-a_2

  = 13 – 9

d = 4

Here differences are not equal.

So table 2 not represents an arithmetic sequence.

Table 3:

d=a_2-a_1

  = 7.3 – 8.7

d = –1.4

d=a_3-a_2

  = 5.9 – 7.3

d = –1.4

d=a_4-a_3

  = 4.5 – 5.9

d = –1.4

d=a_5-a_4

  = 3.1 – 4.5

d = –1.4

Here differences are equal.

So table 3 represents an arithmetic sequence.
