malfutka [58]

Answer:

Step-by-step explanation:

Giving the following information:

The value of the savings bond increases by 3% each year. One year after it was purchased, the value of the savings bond was $515.

<u>To calculate the original value of the bond, we need to use the following formula:</u>

OV= PV/(1+i)^n

OV= original value

PV= present value

i= increase rate

n= number of months

OV= 515 / (1,03^12)

Solve the equation by completing the square. Round to the nearest hundredth if necessary. x2 + 2x = 17
yawa3891 [41]
--------------------------------------------------------
Equation Given
--------------------------------------------------------
x² + 2x = 17

--------------------------------------------------------
Add the constant to make it perfect square
--------------------------------------------------------
x² + 2x + (2/2)² - ²(2/2)² = 17

--------------------------------------------------------
Evaluate the brackets
--------------------------------------------------------
x² + 2x + (1)² - ²(1)² = 17

--------------------------------------------------------
Form the perfect square
--------------------------------------------------------
(x + 1)² - 1 = 17

--------------------------------------------------------
Add 1 to both sides
--------------------------------------------------------
(x + 1)² = 17 + 1
(x + 1)² = 18

--------------------------------------------------------
Square root both sides
--------------------------------------------------------
√(x + 1)² = \pm√18

--------------------------------------------------------
Solve for x
--------------------------------------------------------
x = 4.24 - 1 or - 4.24 -1

x = 3.24 or - 5.24 (nearest hundredth)

--------------------------------------------------------
Answer: x = x = 3.24 or - 5.24
