Answer:
160
Step-by-step explanation:
4 is too low, 90 cant be divided by 8 and 160 is the only answer even though it is highest number
if they are optional
all are correct
<h3>step by step instructions:</h3>
Correct option is
D
All are correct
the equation of a given progressive wave is
y=5sin(100πt−0.4πx) ......(i)
The standard equation of a progressive wave is
y=asin(ωt−Kx) ...(ii)
Comparing (i) and (ii), we get
a=5m,ω=100π rad s
−1
,k=o.4πm
−1

Subtract the 12x^2 first.
5x - 4 = 6
Add the four
5x = 10
Then divide the 5 from both sides
X = 2

Hello Ashley!
This is an isosceles triangle. How do we know? Well, the two little bar they put means that it is isosceles. When you add all the angles together, you MUST find them equal to 180. Another you need to keep in mind is that the angle that are face to face with each other are ALWAYS equal.
Too much talking...we gonna solve the problem.
x + x + 72 = 180
2x + 72 = 180
2x = 180 - 72
2x = 108
x = 108/2
x= 54
That's the answer .
---------------------
What did we say earlier? We said that when we add all the angles together we MUST find them equal to 180. So, we gonna replace x by 54
54 + 54 + 72 = 180
180 = 180
So.. yes we got it right!
54 is the correct answer.
Good luck with your studies!
