Answer:

Step-by-step explanation:

What is the slope of the line? The graph is hard to see, so can't really calculate that, please reupload

What does the slope represent? Increase in costs of Hot Yoga

2. (0,25)

Not sure if that number is 25, but the most bottom dot & on the black line

Y int represents where they started at, minimum cost

Unsure about last 2

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we know that "Angle opposite to greater side is smaller or angle opposite to smaller side is larger".

So, ∠AOD is opposite to side 'AD' which is equal to 8.11

Similarly, ∠AOB is opposite to side 'AB' which is equal to 8.

So, ∠AOB>∠AOD

Hence, Option 'B' is correct.

Let

Mrrafil [7]

$\vec F(x,y,z)=z\tan^{-1}(y^2)\,\vec\imath+z^3\ln(x^2+7)\,\vec\jmath+z\,\vec k$

has divergence

$\nabla\cdot\vec F(x,y,z)=\dfrac{\partial(z\tan^{-1}(y^2))}{\partial x}+\dfrac{\partial(z^3\ln(x^2+7))}{\partial y}+\dfrac{\partial z}{\partial z}=1$

If $S$ includes the disk $x^2+y^2=25$ which is contained in the paraboloid, then by the divergence theorem the flux is

$\displaystyle\iint_S\vec F\cdot\mathrm d\vec S=\int_0^{2\pi}\int_0^5\int_2^{27-r^2}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta=\boxed{\frac{625\pi}2}$

If the disk is not part of $S$ , then subtract the flux of $\vec F$ across the disk (with downward orientation; call it $D$ ). Parameterize $D$ by

$\vec s(u,v)=u\cos v\,\vec\imath+u\sin v\,\vec\jmath+2\,\vec k$

where $0\le u\le5$ and $0\le v\le2\pi$ , with normal vector

$\dfrac{\partial\vec s}{\partial v}\times\dfrac{\partial\vec s}{\partial u}=-u\,\vec k$

Then the flux of $\vec F$ across $D$ is

$\displaystyle\iint_D\vec F\cdot\mathrm d\vec S=-2\int_0^{2\pi}\int_0^5u\,\mathrm du\,\mathrm dv=-50\pi$

which makes the flux across $S$ , $\dfrac{625\pi}2-50\pi=\boxed{\frac{615\pi}2}$ .

Help with geometry please

Answer:

The answer to your question is: n = 95°

Step-by-step explanation:

The sum of the suplementary angles equals 180°

Then

121 + x = 180

x = 180 - 121

x = 59°

144 + y = 180

y = 180 - 144

y = 36°

The sum of the internal angles in a triangle equals 180°

x + y + z = 180

59 + 36 + z = 180

z = 180 - 59 - 36

z = 85

Finally

n + 85 = 180

n = 180 - 85

n = 95°
