Answer:

*assuming you know the concept of proportionality*

since L is directly proportional to T, an increase in L will result in an increase in T

so the solution of the first part is increases

in part 2, y is inversely proportional to x

which means that an increase in y will result in a decrease in x and vice-versa

So the answer of the second part is decreases

in part 3, since x is directly proportional to y, an increase in x will result in an increase in y

professor190 [17]
Well, from 2008 to 2010 is just 2 years, so let's say the initial amount is the 19300 from 2008, how many will it be in 2010?

\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &19300\\
r=rate\to 20\%\to \frac{20}{100}\to &0.20\\
t=\textit{elapsed time}\to &2\\
\end{cases}
\\\\\\
A=19300(1+0.2)^2

How am I supposed to integrate this?
svlad2 [7]
6x^2-4x+1=6\left(x-\dfrac13\right)^2+\dfrac13\ge0

which means the parabola lies above the x-axis over its entire domain. This means the area is given by

\displaystyle\int_{-1}^2(6x^2-4x+1)\,\mathrm dx=2x^3-x^2+x\bigg|_{x=-1}^{x=2}=10-(-5)=15

Answer:

The y-intercept is b=0

The y-intercept represents the initial quantity of gas in the canister which is zero.

Step-by-step explanation:

The y-intercept is where the graph of the straight line  touches the y-axis.

From the graph, the y-intercept is the origin (0,0).

Recall that the slope intercept form of a straight line is y=mx+b, where b=0 is the y-intercept in this case.

Since the graph represents the amount of gasoline in a canister after Joshua begins to fill it at the gas station pump, the y-intercept means the initial gallons of gas in the canister is zero.
