Answer:
4x^2 - 1 = 0
Step-by-step explanation:
x = 1/2, x = -1/2
2x = 1, 2x = - 1
2x - 1 = 0, 2x + 1 = 0
( 2x - 1 )( 2x + 1 ) = 0
4x^2 - 1 = 0
Answer:
X=-5/2
Step-by-step explanation:
First for Y=2x+5 you change the y into 0
Then you replace the 0 with 2x but change the sign so it will be -2x so it will look like -2x=5
then you divide both sides by 2
Finally you get -5/2

Answer:
Number of year = 13 year and 6 month approx.
Step-by-step explanation:
Given:
Amount invested = $80,000
Rate of interest = 6% compounded continuously
Future value of investment = $175,600
Find:
Number of year
Computation:
Future value of investment = Amount invested[1 + Rate of interest]ⁿ
175,600 = 80,000[1+6%]ⁿ
175,600 = 80,000[1+0.06]ⁿ
175,600 = 80,000[1.06]ⁿ
Number of year = 13.492 year
Number of year = 13 year and 6 month approx.
