Answer 1

$\tt\displaystyle F=2,3c-1,1\\2,3c=F+1,1\\\boxed{c=\frac{F+1,1}{2,3}}\\\\F=14+1,4c\\1,4c=F-14\\\boxed{c=\frac{F-14}{1,4}}\\\\t=\sqrt{\frac{2h}{a}}\\t^2=\frac{2h}{a}\\2h=at^2\\\boxed{h=\frac{at^2}{2}}\\\\Q=cm(t_2-t_1)\\t_2-t_1=\frac{Q}{cm}\\ \boxed{t_2=\frac{Q}{cm}+t_1}\\\\ a=2b-3c\\2b=a+3c\\\boxed{b=\frac{a+3c}{2}}\\\\ k=c-3b\\-3b=k-c\\\boxed{b=\frac{c-k}{3}}\\\\ t=2x-4y\\-4y=t-2x\\\boxed{y=\frac{2x-t}{4}}\\\\ S=2\pi r(r+H)\\r+H=\frac{S}{2\pi r}\\ \boxed{H=\frac{S}{2\pi r}-r}$

$\tt\displaystyle r=\frac{2S}{P}\\rP=2S\\\\ \boxed{P=\frac{2S}{r}}$
