Answer:

x≥13

Step-by-step explanation:

Hello

I think I can help you with this

step 1

Lets see how much money jon earns per week

$180 (always, it does not depend on the sales)

$25 for each sale=25* sale

$25*number of sales

earning= $180+$25*number of sales

Let

earnings=e

number of sales=x

(1)e=$180+$25x

Step 2

make the inequality

he need to earn at least  $500, that is the same that $500 or more ($500.∞)

(2)e≥500

mixing (1) and (2)

$180+$25x ≥$500

x can be isolated

$25x ≥$500-$180

$25x ≥$320

x≥320/25

x≥12.8

he can not make 0.8 sales , so he needs 13 sales or more.(13,∞)

Have a great day

Find the flux of F=(x^5+y^5+z^5-2x-3y-4z)i+sin(2y)j+4zsin^2(y)k across the surface of the tetrahedron bounded by the coordinate
Tju [1.3M]
Use the divergence theorem.

\mathbf F(x,y,z)=(x^5+y^5+z^5-2x-3y-4z)\,\mathbf i+\sin2y\,\mathbf j+4z\sin^2y\,\mathbf k
\implies(\nabla\cdot\mathbf F)(x,y,z)=\dfrac{\partial(x^5+y^5+z^5-2x-3y-4z)}{\partial x}+\dfrac{\partial(\sin2y)}{\partial y}+\dfrac{\partial(4z\sin^2y)}{\partial z}=5x^4-2+2\cos2y+4\sin^2y

The flux of \mathbf F across the tetrahedron's surface S is then given by the integral of \nabla\cdot\mathbf F over the interior of the tetrahedron \mathbf R.

\displaystyle\iint_S\mathbf F\cdot\mathrm dS=\iiint_T\nabla\cdot\mathbf F\,\mathrm dV
=\displaystyle\int_{x=0}^{x=1}\int_{y=0}^{y=1-x}\int_{z=0}^{z=1-x-y}(5x^4-2+2\cos2y+4\sin^2y)\,\mathrm dz\,\mathrm dy\,\mathrm dx
=\dfrac1{42}

nika2105 [10]

Answer:

1. To convert cubic inches to cubic feet we divide the figure by 1728 (there are 1728 cubic inches in a cubic foot).

2. Measure the length, width and height of the box in inches. 2. Multiply the length, width and height and divide the resulting number by 1,728. This is the container's volume in cubic feet.

The range of 8,7,12,7,11,10,7,12
allsm [11]

Answer:

a) Median: 9

b) Range: 5

c) Mode: 7

Explanation:

The median is the number in the middle.

First, you put the numbers in order: 7, 7, 7, 8, 10, 11, 12, 12

The middle of this is 8 and 10, so you plus them and divide by to 2, then it gives 9, so the median is 9.

To find the range, you minus the highest number and the lowest number, 12-7=5.

Mode is the most occurring and repetitive number, in this case, 7, because it is written 3 times.
