Answer 1

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

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