Answer:
The correct answer is b.
Step-by-step explanation:
The wave equation is given generally as:
c(x, t) = Acos(kx - wt)
Where A = amplitude
k = wave number
w = angular frequency.
x = horizontal distance moves by the wave.
t = time
The options show to us that the wave depends only on t and not (x, t).
Hence, the wave equation becomes:
c(t) = Acos(wt)
Given that:
A = 5 V
f = 1 * 10⁶ Hz
Angular Frequency, w, is given as:
w = 2πf
w = 2 * π * 1 * 10⁶ Hz
w = 2π(1 * 10⁶)
The wave equation becomes:
c(t) = 5cos(2*π*1*10⁶)
The correct answer is b.
Answer:
6w-60x+6
Step-by-step explanation:
6(w-10x+1)
6w+6(-10)+6*1
6w-60x+6
Answer:
x = 3.5
Step-by-step explanation:
15(1/2) = 7.5
7.5+6 =13.5
subtract 17 and divide by -1 to isolate x 13.5-17/-1
x = 3.5

Answer:
4
Step-by-step explanation:
The function definition tells you its domain is ...
-6 < x ≤ 4
Values -7, -6, and 5 are not in this domain.
Of the listed values, only 4 is in the domain.
It is 93 million miles away from earth. hope that helped
