Despejar c
f =  \frac{9c}{5}  + 2ae
Despejar c, r, t
i =  \frac{c \times r \times t}{100}
Despejar t2
 \frac{ {p}^{1} }{ {p}^{2} }  =  \frac{ {t}^{1} }{t {}^{2} }
Despejar Vf, Vo, a, e
 {v}^{2}f =  {vo }^{2}  + 2ae
Despejar n, p
v =  \frac{n \times r \times 7}{100}
Ayúdenme plox :'v

Respuesta:


1.-

\mathsf{c=\frac{5f-10ae}{9}}


2.-

\mathsf{c=\frac{100i}{rt}}\\\\\mathsf{r=\frac{100i}{ct}}\\\\\mathsf{t=\frac{100i}{cr}}


3.-

\mathsf{t=\sqrt{pt}}


4.-

\mathsf{v_{f}^{2}=v_{o}^{2}+2ae}\\\\\mathsf{v_{f}=\sqrt{v_{o}^{2}+2ae}}\\\\\mathsf{v_{o}^{2}=v_{f}^{2}-2ae}\\\\\mathsf{v_{o}=\sqrt{v_{f}^{2}-2ae}}\\\\\mathsf{2ae=v_{f}^{2}-v_{o}^{2}}\\\\\mathsf{a=\frac{v_{f}^{2}-v_{o}^{2}}{2e}}\\\\\mathsf{e=\frac{v_{f}^{2}-v_{o}^{2}}{2a}}


Explicación paso a paso:

1.- Despejando c:


\mathsf{f=\frac{9}{5}c+2ae}\\\\\mathsf{f=\frac{9c+10ae}{5}}\\\\\mathsf{5f=9c+10ae}\\\\\mathsf{9c=5f-10ae}\\\\\mathsf{c=\frac{5f-10ae}{9}}


2.- Despejando c,r,t


\mathsf{i=\frac{crt}{100}}\\\\\mathsf{100i=crt}\\\\\mathsf{c=\frac{100i}{rt}}\\\\\mathsf{r=\frac{100i}{ct}}\\\\\mathsf{t=\frac{100i}{cr}}


Despejando t²


\frac{p}{p^{2}}=\frac{t}{t^{2}}\\\\t^{2}p=p^{2}t\\\\t^{2}=\frac{p^{2}t}{p}=pt\\\\t=\sqrt{pt}


Despejando Vo,Vf,a y e


v_{f}^{2}=v_{o}^{2}+2ae\\\\v_{f}=\sqrt{v_{o}^{2}+2ae}\\\\v_{o}^{2}=v_{f}^{2}-2ae\\\\v_{o}=\sqrt{v_{f}^{2}-2ae}\\\\2ae=v_{f}^{2}-v_{o}^{2}\\\\a=\frac{v_{f}^{2}-v_{o}^{2}}{2e}\\\\e=\frac{v_{f}^{2}-v_{o}^{2}}{2a}
