The formula for momentum is:
M=Mass*Velocity
From this formula we can derive the formula for velocity:
V=Momentum/Mass
We already know momentum (10 kg m/s) and mass (2 kg). Let's plug in the numbers into the formula:
V=10/2
V=5 m/s
widest to narrowest: y=3/2x2, y= -1/2x2, y= 1/4x2
P=2L+2H
First, isolate 2H:
2H=P-2L
Second, get a singular value of H (just H):
2H/2=(P-2L)/2
Final answer:
H=
Answer:
C) π/6
Step-by-step explanation:
The area under the curve from x=-π/2 to x=k is 3 times the area under the curve from x=k to x=π/2.

Old price: p1 = $ 3.90;
New price: p2 = $ 3.40.
The percentual decrease is given by
d(%) = [ (p2 - p1) / p1 ] * 100 %
d(%) = [ (3.40 - 3.90) / 3.90 ] * 100 %
d(%) = [ - 0.50 / 3.90 ] * 100 %
d(%) = - 0.128 * 100 %
d(%) = - 12.8 % (approximately)
So the price fell 12.8 % approximately.
I hope this helps. =)
