So a general harmonic equation is Asin(2πt/T). Little t is just a variable. 6 inches is the height of one maximum and one minimum from equilibrium, so that is the amplitude A. T is the period, or the time of one cycle (or wavelength), which is 2 seconds.
The equation is therefore (in terms of seconds and inches), 6*sin(2πt/2), or 6*sin(πt).
Answer:
fish
Step-by-step explanation:
Cows=10 units
horses=3 units
if 20 cows then
10 units=20 then
1 unit=2
so horses=3 units
1 unit=2
2 times 3=6
6 horses

Answer: i) 216 liters ii) 60 cm
<u>Step-by-step explanation:</u>
i) 216,000 cm³ × 1 liter/1000 cm³ = 216 liters
ii) ![\sqrt[3]{216,000\ cm^3} =60\ cm](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B216%2C000%5C%20cm%5E3%7D%20%3D60%5C%20cm)
