One month, Ruby worked 6 hours more then Isaac, and Shetland worked 4 times as many hours as Rudy. Together they worked 126 hour

s. Find the number of hours each person worked

If we assume the number of hours Isaac worked is x hours. So in that case the number of hours Ruby worked must be 6 + x. And similarly Shetland worked around 4 (6+x) hours.

So we can easily form an expression that gives us how many hours each worked. So basically x + 6 + x + 24 + 4x = 126. So 6x = 96/6 = 16.

SO Isaac worked for 16 hours. Rudy worked for 22 and Shetland worked for the rest.

Triangle XYZ is shown on the coordinate plane below:
Ivanshal [37]
The line y=1 is the horizontal line passing through the point (0, 1). We have drawn it with red.

The reflection across this line of each point X, Y, and Z is such that the distance of each  X, Y, and Z is equal to the distance of each X', Y', and Z', respectively, to the red line.

According to our drawing, we see that the coordinates of X' are (3, 3).

Answer: a.

Find the flux of the vector field F = 〈e-z,4z,6xy) across the curved sides of the surface S = {(x,y,z): z= cos y, lys π, 0sxs4}
Len [333]

I'll go ahead and assume you meant to say that <em>S</em> is the surface given by

S = \left\{(x,y,z) \mid z = \cos(y)\text{ with } 0\le y\le \pi\text{ and }0\le x\le4\right\}

This immediately gives us a parameterization for the surface,

\vec r(x, y) = \left\langle x, y, \cos(y)\right \rangle

The upward-pointing normal vector to this surface is then

\vec n = \dfrac{\partial\vec r}{\partial x} \times \dfrac{\partial\vec r}{\partial y} = \left\langle0,\sin(y),1\right\rangle

Then the flux of \vec F(x,y,z) = \left\langle e^{-z}, 4z, 6xy\right\rangle across <em>S</em> is

\displaystyle \iint_S \vec F(x,y,z)\cdot\mathrm d\vec s = \int_0^4\int_0^\pi \vec F(x,y,\cos(y))\cdot\vec n\,\mathrm dy\,\mathrm dx \\\\ = \int_0^4\int_0^\pi \left\langle e^{-\cos(y)},4\cos(y),6xy\right\rangle \cdot \left\langle0,\sin(y),1\right\rangle \,\mathrm dy\,\mathrm dx \\\\ = \int_0^4\int_0^\pi (4\sin(y)\cos(y)+6xy)\,\mathrm dy\,\mathrm dx \\\\ = 2 \int_0^4\int_0^\pi (\sin(2y) + 3xy)\,\mathrm dy\,\mathrm dx = \boxed{24\pi^2}

Which set of measurements could make a triangle?
Sedaia [141]

Answer:

3.) a. 9mm b. 10mm c. 8mm

Step-by-step explanation:

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

Formula:

a + b = (answer) > c

a + c = (answer) > b

b + c = (answer) > a

try to solve it yourself so you can do it on your own in the future.
