Ymorist [56]

Given :

Price of property , P = $145000 .

Money paid off in two ways a short term note at 11% interest and a long term note at 8% interest.

Total interest , I = $13850 .

To Find :

The amount of each note .

Solution :

Let , x money is paid off in 11 % interest rate and ( 145000-x) in 8% interest rate.

Therefore , their sum of interest in mathematics is given by :

\dfrac{11x}{100}+\dfrac{8(145000-x)}{100}=13850\\\\11x+1160000-8x=1385000\\\\3x=225000\\\\x=\$75000

Therefore , the amount of note is $75000 and $70000 for 11% and 8% interest rate respectively .

Verify each trigonometric equation by substituting identities to match the right hand side of the equation to the left hand side
inysia [295]

(sin x)/(1-cosx) + sinx/(1-cosx) =

2 csc x

We have like denominators.

Just add the numerators.

(2 sin x)/(1 - cos x) = 2 csc x

[1/(1 - cos x)](2 sin x) = 2 csc x

Take it from here.
