Answer:
so here tje answer is
50 <em>/</em><em> </em><em>1</em><em>0</em><em> </em><em>=</em><em> </em><em>-</em><em>k</em><em> </em>
<em>s</em><em>o</em><em> </em><em>the</em><em> </em><em>v</em><em>a</em><em>l</em><em>u</em><em>e</em><em> </em><em>o</em><em>f</em><em> </em><em>k</em><em> </em><em>=</em><em> </em><em>5</em>
51. I checked the comments but I still didn't understand it, sorry :/
54.
(43+45+47+49)=184
They are all odd and they are in consecutive order (one after another)
T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R
At 85 mph we have
T = 720 / 85 = 8.47 hours (answer)
To find the answer, you have to divide-
the people arriving/minute
So it would be -
450/15 = 30
There are 30 people arriving each minute.
im not sure if you want the solution or interval notation. i'll put both
solution: -oo < x < oo
interval notation: (-oo, oo)
