A car is traveling at a constant speed. It travels \( 3 \frac{1}{2} \) miles in \( 5 \frac{1}{4} \) minutes.

Soluciona las siguientes integrales definidas. a. \( \int_{1}^{3}\left(2 x^{4}+5 x^{3}+x^{2}-2 x+3\right) d x \) b. \( \int_{2}^{4}\left(3 x^{2}+x\right) d x \)

\( 4 m x^{2}+2 x-(3 m-2)=0 \) 4 Consider the equation

Write the complex number \( \frac{3+2 i}{1-4 i} \) in the form \( a+b i \).
