Problem $4(5$ points$)$

When programming the below equations declare and initialize the below variables as:

double a $=2\mathrm{.}5$;

double b $=7\mathrm{.}0$;

double c $=10\mathrm{.}0$;

double d $=2\mathrm{.}0$;

double x $=5\mathrm{.}0$;

double y $=4\mathrm{.}0$;

a$.,b^2-4ac$

b$.,a+b-c$

c$.\frac{a+b}{c+d}$

d$.\frac{1\mathrm{.}0}{y+x^2}$

e$.\frac{1\mathrm{.}0}{\sqrt[\phantom{2}]{x^3}}$
