Answer:

$0.5x + 4 + 0.9x = x + 5$

collect like terms together:

$0.5x + 0.9x - x = 5 - 4 \\ x(0.5 + 0.9 - 1) = 1 \\ 0.4x = 1 \\ x = \frac{1}{0.4} \\ \\ { \boxed{ \boxed{x = 2.5}}}$

What exponential function is the best fit for the data in the table?

Murrr4er [49]

Answer: The correct answer is choice D.

There are multiple ways to get to the right answer. You could plot the points on a graphing calculator. Then, graph each function to determine which equation matches the points.

You could also input the x values and see which equation produces the y values in the chart.

On thing to notice is the we have negative output values, there we need to pick either B or D, so the values go beneath the x-axis.

Let divf = 6(5 − x) and 0 ≤ a, b, c ≤ 12. (a) find the flux of f out of the rectangular solid 0 ≤ x ≤ a, 0 ≤ y ≤ b, and 0 ≤ z ≤

dusya [7]

Continuing from the setup in the question linked above (and using the same symbols/variables), we have

$\displaystyle\iint_{\mathcal S}\mathbf f\cdot\mathrm d\mathbf S=\iiint_{\mathcal R}(\nabla\cdot f)\,\mathrm dV$
$=\displaystyle6\int_{z=0}^{z=c}\int_{y=0}^{y=b}\int_{x=0}^{x=a}(5-x)\,\mathrm dx\,\mathrm dy\,\mathrm dz$
$=\displaystyle6bc\int_0^a(5-x)\,\mathrm dx$
$=6bc\left(5a-\dfrac{a^2}2\right)=3abc(10-a)$

The next part of the question asks to maximize this result - our target function which we'll call $g(a,b,c)=3abc(10-a)$ - subject to $0\le a,b,c\le12$ .

We can see that $g$ is quadratic in $a$ , so let's complete the square.

$g(a,b,c)=-3bc(a^2-10a+25-25)=3bc(25-(a-5)^2)$

Since $b,c$ are non-negative, it stands to reason that the total product will be maximized if $a-5$ vanishes because $25-(a-5)^2$ is a parabola with its vertex (a maximum) at (5, 25). Setting $a=5$ , it's clear that the maximum of $g$ will then be attained when $b,c$ are largest, so the largest flux will be attained at $(a,b,c)=(5,12,12)$ , which gives a flux of 10,800.

Given the definition of like terms and hence simplify by removing brackets and collecting like terms :

Vedmedyk [2.9K]

First, distribute to cancel out brackets
= m-n+p-2m+2p-3n-n+m-2p

Collect like terms
= -5n+p

Your answer: -5n + p

Hope this helped :)
