Solution:
Remember to follow PEMDAS!
= 3 + 2 ⋅ [(2 + 1) ⋅ 5 + 8]
= 3 + 2 ⋅ [(3) ⋅ 5 + 8]
= 3 + 2 ⋅ [(15) + 8]
= 3 + 2 ⋅ [23]
= 3 + 46
= 49

Answer:
84
Step-by-step explanation:
A=bh/2.
A=(21*8)/2
A=168/2
A=84
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.
2x+15=9
2x= -6
so the answer is -3
