2 sin^2 (x) + 3 sin (x) + 1 = 0<br> help me find the solution
Fed [463]

Answer:

Step-by-step explanation:

\[2~ sin^2 x+3sin x+1=0\]

\[2sin^2x+2sin x+sin x+1=0\]

2sinx(sin x+1)+1(sin x+1)=0

(sin x+1)(2 sin x+1)=0

either sin x+1=0

sin x=-1=sin 3π/2=sin (2nπ+3π/2)

x=2nπ+3π/2,where n is an integer.

or 2sin x+1=0

sin x=-1/2=-sin π/6=sin (π+π/6),sin (2π-π/6)=sin (2nπ+7π/6),sin (2nπ+11π/6)

x=2nπ+7π/6,2nπ+11π/6,

where n is an integer.

yan [13]

Answer:

Total amount in Joe's savings account T = $448

Step-by-step explanation:

Given;

time t = 3 years

Annual rate r = 4%

Principal P = $400

Simple interest can be expressed as;

I = Prt/100

Substituting the given values;

I =400×4×3/100 = 4800/100

I = $48

Total amount in account T;

T = P + I = $400 + $48 = $448
