For this case we have to:
x: It is the variable that represents the number of compact discs.
The cost function must be found considering that each disk costs $7.13. So:
Thus, to find the total cost of "x" compact discs (in $) we substitute the number of discs in the cost function.
Answer:
If the Amplitud is 11×2=22cm and the wave was in shm then we can get the wavelength as 11×2=22s.
From the wave equation,
v=fλ Where v⇒speed
f⇒frequency and
λ⇒Wavelength
And we know that;
f=1/T
f = 1/4 =0.25 Hz
∴v = 0.25 ×22 = 5.5 cm/s
Since we know know the speed of the object we can get its time it takes from (0-6.5) cm.
v = fλ = λ/T
∴T = λ/v
= 6.5/5.5
= 1 2/11
= 1.181818s
The time taken for the object <span>to move from x = 0.0 cm to x = 6.5 cm is </span>1.181818s
