Use the chain rule to compute \(\frac{d f(x(t),y(t),z(t))}{dt}\bigg|_{t=0}\) where \(f(x,y,z)=x^2+xy-z\) and \((x(t),y(t),z(t))=(t,t,1)\).

The following dilutions were set up to titer an antibody. The following results were obtained: 1:4+, 1:8+, 1:16+. 1:32+, 1:64+. 1:128-. How should the titer be reported out?

Heather, a 37-year-old woman, is a first-time donor at your blood center. She is a healthy donor, has an unremarkable medical history, and is not taking any medications. Initial ABO phenotyping (RBC’s antigens) results are as follows: ABO Testing Results Donor Red Cells Antigen testing (Front Type)   Antiserum-A reagent Antiserum-B reagent Antiserum-D reagent 0 reaction or negative 4+ reaction 4+ reaction     1. With the antiserum-B reagent and antiserum-D reagent reacting with Heather’s antigens on her RBC’s,  what ABO blood type does Heather presumably possess? 2. What does the antiserum-A and the zero or negative reaction indicate? 3. Name 3 functions of an antigen. 

Integrate \(x^2+y^2\) over the triangle bounded by the \(x\)-axis, \(y\)-axis and the line \(y=1-x.\)
