$\text{L.H.S}\\\\=\dfrac{\sin A \tan A}{1- \cos A}\\\\\\=\dfrac{\sin A \cdot \tfrac{\sin A}{\cos A} }{ 1- \cos A}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~;\left[\tan A = \dfrac{\sin A }{\cos A}\right]\\\\\\=\dfrac{\tfrac{\sin^2 A}{ \cos A}}{1- \cos A}\\\\\\=\dfrac{\sin^2 A}{\cos A(1-\cos A)}\\\\\\=\dfrac{1-\cos^2 A}{\cos A( 1- \cos A)}~~~~~~~~~~~~~~~~~~~~~~~~;[\sin^2 A + \cos^2 A = 1]\\\\\\$

$=\dfrac{(1+ \cos A)(1 - \cos A)}{\cos A(1 - \cos A)}\\\\\\=\dfrac{1+ \cos A}{ \cos A}\\\\\\=\dfrac{1}{\cos A} + \dfrac{\cos A}{ \cos A}\\\\\\=\sec A + 1 \\\\\\=1+ \sec A\\\\\\=\text{R.H.S}\\\\\text{Proved.}$

Answer:

SEE BELOW PLEASE GIVE BRAINLIEST

Step-by-step explanation:

YEAR 1: 40000 X .03 = 1200 40,000 + 1200 = 41200

YEAR 2: 41,200 X .03 = 1236 41,200 + 1236 = 42436

YEAR 3: 42436 X .03 = 1273.08 42436 + 1273.08 = 43709.08

YEAR 4: 43709.08 x .03 = 1311.27 43709.08 + 1311.27 = 45020.35

YEAR 5: 45020.35 X .03 = 1350.61 45020.35 + 1350.61 = 46370.96

YEAR 6: 46370.96 X .03 = 1391.13 46370.96 + 1391.13 = 47762.09

YEAR 7: 47762.09 X .03 = 1432.86 47762.09 + 1432.86 = 49194.95

YEAR 8: 49194.95 X .03 = 1475.85 49194.95 + 1475.85 = 50670.80

YEAR 9: 50670.80 X .03 = 1520.12 50670.80 + 1520.12 = 52190.92

YEAR 10: 52190.92 X .03 = 1565.73 52190.92 + 1565.73 = 53756.65

YEAR 11: 53756.65 X .03 = 1612.70 53756.65 + 1612.70 = 55369.35

YEAR 12: 55369.35 X .03 = 1661.08 55369.35 + 1661.08 = 57030.43

YEAR 13: 57030.43 X .03 = 1710.91 57030.43 + 1710.91 = 58741.34

YEAR 14: 58741.34 X .03 = 1762.24 58741.34 + 1762.24 = 60503.58

YEAR 15: 60503.58 X .03 = 1815.11 60503.58 + 1815.11 = 62318.69

YEAR 16: 62318.69 X .03 = 1869.56 62318.69 + 1869.56 = $64,188.25 = $64188
