Monique deposited her money in the bank to collect interest. in the first month, she had $225 in her account. after the sixth month, she had $273.75 in her account. use sequence notation to represent the geometric function. an = 273.75 ⋅ (1.04)n−1 an = 273.75 ⋅ (1.22)n−1 an = 225 ⋅ (0.22)n−1 an = 225 ⋅ (1.04)n−1

plz hurry

The correct option is D)

Step-by-step explanation:

Consider the provided information.

In the first month, she had $225 in her account.

After the sixth month, she had $273.75 in her account.

The geometric sequence is given by:

In the first month, she had $225 in her account. After the sixth month, she had $273.75 in her account.

Substitute a=225, and n=6 in above formula.

Hence, the value of r is 1.04

Therefore, the required sequence notation to represent the geometric function is

Hence, the correct option is D)

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

irrational, cannot
