Step-by-step explanation:
line A and D are parallel because they have the same koeficient 3=3
line C is perpendicular to line A because
k1*k2=-1
3*(-1/3)=-1
which is a true statement
12.38 in expanded form is write like:-
10 + 2 + .3 + .08 = 12.38
To
write a number in expanded form just means to write the number in a
layout and when you add it up it will become the number you needed to
write in expanded form.
So, 12.38 written in expanded form is:- 10 + 2 + .3 + 0.8

1/5=x/4
0.8ft
1/5=x/6
1.2ft
Dimensions are 0.8ft X 1.2ft.
Answer:
t = 1.47 s
Step-by-step explanation:
y(x,t) = 0.6 sin (8 x – 24 t )
compare it with
y = A sin (k x - ω t)
now, A = 0.6
k = 8
ω = 24 rad/s
we know ω = 2πf
we know that
time taken
t = distance/time
= 4.4 / 3
t = 1.47 s
