The pair of points is on the graph of an inverse variation. Find the missing value. (1.6, 6) and (8, y) 0.03 30 1.2 0.83
ZanzabumX [31]
One may note that (1.6 , 6)  is just another way to say x = 1.6 when y = 6.

and that (8 , y) is another way to say x = 8 and y is who knows.

\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad  y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad  variation
\end{array}\\\\
-------------------------------

\bf \textit{we know that }
\begin{cases}
x=1.6\\
y=6
\end{cases}\implies 6=\cfrac{k}{1.6}\implies 6(1.6)=k\implies 9.6=k
\\\\\\
\qquad therefore\qquad \boxed{y=\cfrac{9.6}{x}}
\\\\\\
\textit{when x = 8, what is \underline{y}?}\qquad y=\cfrac{9.6}{8}

You are holding a movie party and want to make your own boxes for popcorn out of some old movie posters, which are 8.5 x 11 inch
kozerog [31]

Answer:

x = 3,17 in

Step-by-step explanation:

Movie poster dimensions:

8,5  and 11  inches

Let´s call  "x" the side of the square, to cut in each corner, then the volume of the open box will be:

V(ob)  = ( 8,5 - x ) * ( 11 - x )* x

Then volume as a function of x

V(x)  =  ( 8,5 - x ) * ( 11 - x )* x    or    V(x)  = ( 93,5 - 8,5*x - 11*x + x² )*x

V(x)  = 93,5*x -19,5*x² + x³

Taking derivatives on both sides of the equation:

V´(x) =  93,5 - 39*x  +  3*x²

V´(x) = 0    ⇒     93,5 - 39*x  +  3*x² = 0

3*x² - 39*x  + 93,5  = 0

Solving for x

x₁,₂  = ( 39 ± √1521 - 1122 )/6

x₁,₂  =  39 ± 19,97 / 6

x₁  = 19,03/6        x₁  = 3,17 in

x₂  =  58,97 / 6   x₂  = 9,83       dismiss this root (we can´t cut  2 pieces of 9,83 from 8,5 inches

x = 3,17 in
