There are three stocks in the market: A, B, and C. The market betas for the three stocks are Beta(A) = 0.5, Beta(B) = 1.0, Beta(C) =1.5. The expected returns of the three stocks are E[R(A)] = 8%, E[R(B)] = 12%, and E[R(C)] = 17%. Based on these values, is there any violation of CAPM? Please show work.

A bank has issued a six-month, $1.0 million negotiable CD with a 0.53 percent quoted annual interest rate (iCD, sp). a. Calculate the bond equivalent yield and the EAR on the CD. b. How much will the negotiable CD holder receive at maturity? c. Immediately after the CD is issued, the secondary market price on the $1 million CD falls to $998,900. Calculate the new secondary market quoted yield, the bond equivalent yield, and the EAR on the $1.0 million face value CD.
Required A: Bond Equivalent Yield ___ EAR____ (Use 365 days in a year. Do not round intermediate calculations. Round your answers to 3 decimal places.)
Required B: CD Holder will receive at maturity_____(Do not round intermediate calculations. Round your answer to nearest whole number.)
Required C: Bond Equivalent Yield____ Secondary Market Quoted Yield______ EAR_____ (Use 365 days in a year. Do not round intermediate calculations. Round your answers to 4 decimal places.

A 1.0-cm-diameter pipe widens to 2.0 cm, then narrows to 0.5 cm. Liquid flows through the first segment at a speed of 9.0 m/s .
What is the speed in the second segment?
What is the speed in the third segment?
What is the volume flow rate through the pipe?
for the love of god please give me the right answer. everyone has given me the wrong answers so far and i'm pissed off.

A 2 kg disk traveling at 3.0 m/s strikes a 1.0 kg stick of length 4.0 m, that is lying flat on nearly frictionless ice. The disk strikes at the end point of the stick at a distance r=2.0 m from the stick's center. Assume the collision is inelastic and the disk adheres to the stick.The moment of inertia of the stick about its center of mass is 1.33kg*m^2.
a) Does the disk have initial linear momentum?
b) Does the disk have initial angular momentum? If so, where is the axis of rotation?
c) Does the disk have final linear momentum?
d) Does the disk have final angular momentum?
e) If ΔK = 0 for the system, would this collision make any sound?
