1. A company is evaluating the addition of equipment to its present operations. They need to purchase equipment for $160,000. The 5-year MACRS GDS recovery method (see table 7.3) is appropriate for the investment and the total tax rate is 40%. Gross revenue is expected to be $30,000/YEAR while maintenance cost is expected to be $5,000/YEAR. It is expected that operations will shut down by the end of the 4^th year with a salvage value of $20,000.

Part A:

Draw a before tax cash flow diagram

Part B:

Use a table to show the development of the after-tax cash flow

Part C:

If the after-tax MARR is 12%, is the investment profitable?

A researcher studies the effect of cognitive psychotherapy on positive self-regard. The number of positive statements made about oneself is recorded for each participant during the first meeting. After 8 weekly therapy sessions, the measures are repeated for each person. The therapist predicts that cognitive psychotherapy will increase the number of positive statements. For the following data: Before Treatment: 7, 6, 9, 5 After Treatment: 10,12,7,17

Null hypothesis: Cognitive psychotherapy will not increase positive self-regard.

What is the appropriate conclusion from this study?

reject alternative hypothesis

retain alternative hypothesis

reject null hypothesis

fail to reject null hypothesis

A titration is performed by adding 0.791 M KOH to 40 mL of 0.127 M HC₃H₅O₂.

a) Calculate the pH before addition of any KOH.

b) Calculate the pH after the addition of 1.28, 3.21 and 5.42 mL of the base.(Show your work in detail for one of the volumes.)

c) Calculate the volume of base needed to reach the equivalence point.

d) Calculate the pH at the equivalence point.

e) Calculate the pH after adding 5.00 mL of KOH past the equivalence point.

f) Plot pH (y axis) versus volume of KOH added (x axis) for each calculation above. Sketch the titration curve.

Assume the following selected balances appear in their normal debit or credit column in the adjusted trial balance for the Leonard Company:

Required:
a. Use T-Accounts to demonstrate the necessary closing entries for the company at 12/31/13. (T-accounts should show the balance before closing and the balance after closing.)
b.   Determine the Retained Earnings account balance after the year-end closing.

A collision in one dimension

A mass m1 = 2 kg moving at v1i = 3 ms−1 collides with another mass m2 = 4 kg moving at

v2i = −2 ms−1. After the collision the mass m1 moves at v1f = −3.66 ms−1. (a) Calculate the final velocity of the mass m2.

(b) After the collision the mass m1 slides across a surface with coefficient of friction μ = 0.6. Calculate how far it travels before it comes to rest.

A target in a shooting gallery consists of a vertical square wooden board, 0.230 m on a side and with mass 0.700 kg , that pivots on a horizontal axis along its top edge. The board is struck face-on at its center by a bullet with mass 1.60 g that is traveling at 355 m/s and that remains embedded in the board.

A. What is the angular speed of the board just after the bullet's impact?

B. What maximum height above the equilibrium position does the center of the board reach before starting to swing down again?

C. What minimum bullet speed would be required for the board to swing all the way over after impact?

Tobias has a wife and child (Emily) who live with him full-time. Emily is his biological child and is age 13. He and his wife file as Married Filing Jointly. In 2018, Tobias and his wife (she earned $10,000) had $78,000 in total income. After accounting for numerous deductions, etc. (but before accounting for tax credits) Tobias estimates that his federal income tax for the year will be $6,950. Given this limited information, how much do you believe this tax bill will be after accounting for any tax credit(s)?

Group of answer choices

$6,450
