Z varies directly with x and inversely with y. When x=6 and y=2, .z=15. Write function that models variation. Then, find z when
tester [92]
\bf \begin{array}{cccccclllll}
\textit{direct proportional variation}\\\\\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ k}}&\cdot&x
\\
&&  y={{ k }}x
\end{array}\\ \quad \\


\bf \textit{inverse proportional variation}\\\\
\begin{array}{llllll}
\textit{something}&&\textit{varies inversely to}&\textit{something else}\\ \quad \\
\textit{something}&=&\cfrac{{{\textit{some value}}}}{}&\cfrac{}{\textit{something else}}\\ \quad \\
y&=&\cfrac{{{\textit{k}}}}{}&\cfrac{}{x}
\\
&&y=\cfrac{{{  k}}}{x}
\end{array}


\bf \\\\
-------------------------------\\\\
\textit{z varies directly with x}\implies z=kx
\\\\
\textit{and inversely with y}\implies z=\cfrac{kx}{y}
\\\\\\
\textit{we also know that}\quad 
\begin{cases}
x=6\\
y=2\\
z=15
\end{cases}\implies 15=\cfrac{k\cdot 6}{2}\implies 30=6k

\bf \cfrac{30}{6}=k\implies \boxed{5=k}\impliedby \textit{constant of variation}
\\\\\\
thus\implies z=\cfrac{5x}{y}\\\\
-------------------------------\\\\
\textit{what's "z" when }
\begin{cases}
x=4\\
y=9
\end{cases}\implies z=\cfrac{5\cdot 4}{9}

Rachel found this rate of change for the scenario represented in the table.
Alex17521 [72]
THE FUNCTION IS CONTINOUS - True
We see from the table that for every hour given, there will be a value of juice (cups) given. The graph would have been a linear graph between the time 4 hours and 8 hours with no jump or holes in the graph. 

TIME REPRESENTS THE DEPENDANT VARIABLE - False
Time is the independent variable as it does not depend on any other value. The number of cups, on the other hand, depends on the number of hours, hence is a dependent variable

THE SCENARIO IS REPRESENTED BY
A LINEAR FUNCTION, SINCE THE RATE OF CHANGE, IS CONSTANT - True
The rate of change is 53 cups per hour, hence the function is linear.

AS THE AMOUNT OF TIME CONTINUES, THERE ARE FEWER CUPS OF JUICE POURED PER HOUR - False
The rate of change is a positive value, hence the number of cups poured per hour will increase

FOR EVERY ADDITIONAL HOUR, 53 CUPS OF JUICED IS POURED - True
The difference between number of cups poured hourly is a constant of 53

Which is the correct simplification of 2.2x10^4/8.8x10^9
sergij07 [2.7K]
Expression is: 2.2 × 10⁴ / 8.8 × 10⁹
= 1 × 10⁴ / 4 × 10⁹
= 0.25 × 10⁴⁻⁹
= 0.25 × 10⁻⁵
= 2.5 × 10⁻⁶

In short, Your Answer would be: Option D

Hope this helps!
