Hi can someone tell me how is the answer 113?? how do i type it in the calculator?? im confused can someone please explain ASAP!

Trava [24]

You shouldn't need a calculator for this. The quadratic equation is written in standard form.

ax^2 + bx + c = 0

You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.

(-7)^2 - 4(2)(-8)

49 - 4(-16)

49 - (-64)

49 + 64

113

Best of Luck!

Use Stokes' Theorem to evaluate |c F * dr where C is oriented counterclockwise as viewed from above.F(x, y, z) = xyi + 5zj + 7yk

Hunter-Best [27]

Compute the curl of $\vec F$ :

$\vec F(x,y,z)=xy\,\vec\imath+5z\,\vec\jmath+7y\,\vec k\implies\nabla\times\vec F(x,y,z)=2\,\vec\imath-x\,\vec k$

By Stoke's theorem, the (line) integral of $\vec F$ along $C$ is equivalent to the (surface) integral (or flux) of $\nabla\times\vec F$ across $S$ , the oriented surface with boundary $C$ .

Take $S$ to be the part of the plane $x+z=3$ within the cylinder $x^2+y^2=144$ . Parameterize $S$ by

$\vec s(u,v)=u\cos v\,\vec\imath+u\sin v\,\vec\jmath+(3-u\cos v)\,\vec k$

with $0\le u\le12$ and $0\le v\le2\pi$ . Take the normal vector to $S$ to be

$\vec s_u\times\vec s_v=u\,\vec\imath+u\,\vec k$

Then the integral is

$\displaystyle\int_C\vec F\cdot\mathrm d\vec r=\iint_S(\nabla\times\vec F)\cdot(\vec s_u\times\vec s_v)\,\mathrm du\,\mathrm dv$

$=\displaystyle\int_0^{2\pi}\int_0^{12}(2\,\vec\imath-u\cos v\,\vec k)\cdot(u\,\vec\imath+u\,\vec k)\,\mathrm du\,\mathrm dv$

$=\displaystyle\int_0^{2\pi}\int_0^{12}(2u-u^2\cos v)\,\mathrm du\,\mathrm dv=\boxed{288\pi}$

What is the slope or the line represented by the equation y= -2/3 - 5x

Luden [163]

Answer:

- 5

Step-by-step explanation:

We know this because in the formula y = mx + b the - 5 is in place of m (the slope).
