z=-19+3.14 i What are the real and imaginary parts of z ? Choose 1 answer: (A) {:[Re(z)=-19" and "],[Im(z)=3.14]:} (B) {:[Re(z)=3.14 i" and "],[Im(z)=-19]:} (c) {:[Re(z)=-19" and "],[Im(z)=3.14 i]:} (D) {:[Re(z)=3.14" and "],[Im(z)=-19]:}

Complex number definition: We have the complex number z = -19 + 3.14i. The real part of a complex number is the part without the imaginary unit i, and the imaginary part is the coefficient of i.Identifying the real part: Identify the real part of z. The real part is -19.Identifying the imaginary part: Identify the imaginary part of z. The imaginary part is the coefficient of i, which is 3.14.Matching parts to answer choices: Match the real and imaginary parts to the correct answer choice. The real part is Re(z) = -19 and the imaginary part is Im(z) = 3.14.
