Answer:
The interest After 6 years is $ 79.03
Step-by-step explanation:
Given as :
The principal amount deposited in account = $ 700
The rate interest earn = 1.8 % per year
The Time period = 6 years
<u>From Compounded Method </u>
Amount = Principal ×
Or, Amount = $ 700 ×
Or, Amount = $ 700 ×
Or, Amount = $ 700 × 1.1129
∴ Amount = $ 779.03
Now , Interest = Amount - Principal
I.e Interest = $ 779.03 - $ 700 = $ 79.03
Hence The interest After 6 years is $ 79.03 , Answer
Answer:
x ∈ {2π/3, π, 4π/3} ≈ {2.09440, 3.14159, 4.18879}
Step-by-step explanation:
The equation can be put into standard form by adding 1:
2cos²(x) +3cos(x) +1 = 0
(2cos(x) +1)(cos(x) +1) = 0
Values of cos(x) that make this true* are ...
cos(x) = -1/2 . . . . . . . . . true for x=2π/3, x=4π/3
cos(x) = -1 . . . . . . . . . . . true for x=π
