3^-4 = 1/(3^4)
(3^4) = 81
Answer is 1/81
Sinusoidal equations are trigonometric functions involving sine and cosine functions. Graphically, they look like wave patterns having amplitudes and periods. The general form of a sinusoidal equation is
y = A sin(Bx + C) + D
where
A = amplitude
B = frequency
C = shift on starting angle
D = shift of wave on the y-axis
From the given problem, A = 1 and D = 3. There is no value for C because there is no mention of any shift in angle. About the frequency, you can obtain this by getting the reciprocal of the period. Thus, B = 2/π. The complete equation is
y = sin(2x/π) + 3
Answer: New price = rs. 1710
Step-by-step explanation:
<u>Given information</u>
Original price (market price) = rs.1800
Discount rate = 5%
<u>Given expression deducted from the question</u>
New price = Original price × (1 - discount rate)
<u>Substitute values into the expression</u>
New price = 1800 × (1 - 5%)
<u>Simplify parentheses</u>
New price = 1800 × 0.95
<u>Simplify by multiplication</u>
New price =![\boxed{rs.1710}](https://tex.z-dn.net/?f=%5Cboxed%7Brs.1710%7D)
