The vast majority of pulsars are known only from their pulses in:

A neutron star’s immense gravitational attraction is due primarily to its small radius and

The equivalence principle says that a person in an elevator that is in freefall feels the same acceleration as

A furniture produces three types of desks: a children’s model, an office model, and a deluxe model. Each desk is manufactured in three stages: cutting, construction, and finishing. The time requirements for each model and manufacturing stage are given below in the table. Each week the company has available a maximum of 100 hours for cutting, 100 hours for construction, and 65 hours for finishing. If all available time must be used, how many of each type of desk should be produced each week? a) Write the system of linear equations and augmented matrix. b) Show steps in using Gauss or Gauss-Jordan elimination to solve the system. (Answer without substantial work will receive a minimum score.) c) Write the answer in a complete sentence. 

Given the system of equations: a) Write the augmented matrix.   b) Use Gauss-Jordan elimination method to simplify the matrix to a reduced row-echelon form. Show your work! No steps shown – no credit given!   c) Write the solution set for the system of linear equations and check your answer.  

We start with 600 g of radioactive Proactinium-234. 10 hours later we have 200g. a) Find an equation for the amount of Proactinium-234 after hours.   b) How much do we have after 20 hours?   c) When will we have 450 g of Proactinium-234?

The nurse teaches a pregnant client about the presumptive, probable, and positive signs of pregnancy. The client demonstrates an understanding of the nurse’s instructions if they state that probable signs of pregnancy include (select all that apply):

A client comes in for a first prenatal visit at 10 weeks. The client tells the nurse that this is their fourth pregnancy. A first pregnancy ended in miscarriage at twelve weeks. A second pregnancy resulted in a 39-week viable male infant.  A third pregnancy resulted in 35-week twins and they are all living. How would the nurse record this client’s obstetric history using the GTPAL system?

An 18-year-old client comes in to see the health care provider suspecting that she may be pregnant. Upon further testing, she is discovered to be 14 weeks pregnant. She has a lot of questions, including the types of testing that are done in pregnancy as well as what vaccinations she might need. Which vaccinations are recommended during pregnancy [option1] and [option2]?
