(2 – 4t + 5t 2 ) – (3t 2 + 2t – 7)

Ebony E.
Answer:

Distribute the minus sign throughout the parentheses before combining like terms: (2 – 4t + 5t 2 ) – 3(t 2 + 2t – 7) = 2 – 4t + 5t 2 – 3t 2 – 2t + 7 = 2t 2 – 6t + 9.

Question:

Why are troponin and creatine kinase used to diagnose a heart attack?

Ebony E.
Answer:

Because they are released into the blood upon myocardial damage occurs. These would not be good markers for damage to smooth muscle of the GI tract mainly because troponin is not known to be present in smooth muscle, and CK, while present in smooth muscle, is not present in nearly the quantities/activities as in cardiac muscle.
