Answer 1

Create an expression to find the time for the given distance and rate, and find the value of the expression.

Answer 2

d=84 feet; r= 12 feet/second

Answer 3

thats the eqation

Answer 4

help please

Answer 5

\[v=\frac{ dx }{ dt }\]
\[dx=vdt\]
\[\int\limits\limits_{x _{0}}^{x}dx=\int\limits\limits_{0}^{\Delta t}{ vdt }\]
\[\int\limits_{x _{0}}^{x} x=\int\limits_{0}^{\Delta t}(v _{0}+at)dt\]
\[x-x _{0}=v _{0} \Delta t+\frac{ 1 }{ 2 }at ^{2}\]
since\[a=0, x _{0}=0,v _{0}=r,x=d,\Delta t=t\] therefore\[d=rt\]\[t=\frac{ d }{ r }\]

Answer 6

woah thanks

Answer 7

it was supposed to be 1/2a(Delta t)square
sorry about that I wrote 1/2atsquare

Answer 8

its alright
