Answer: C) three times a number minus two is more than 16
Explanation: < represents greater than
Answer:
x = √5 + 4 , -√5 + 4
Step-by-step explanation:
3(x - 4)^2 = 15
/3 /3 (divide both sides by 3)
----------------------
(x - 4)^2 = 5
(x−4)^2⋅1/2 = ±√5 (take square root of both sides)
x - 4 = ±√5 (add 4 on both sides)
+ +4
-----------------
x = √5 + 4 , x = -√5 + 4
Answer:
n = 121
Step-by-step explanation:
Given,
Amount invested = $250,000
Quarterly payment (P) = $5500
Interest Rate (Quarterly) (r) = 8% /4 = 2%
Account balance = $ 0
Present value of Annuity formula ,
Present value = 

1.02⁻ⁿ = 0.091
-n ln(1.02) = ln (0.091)
n = 121
Hence it will take 121 Quarters to account balance $0.
