My answer is 15 and the other person who answered is wrong because they only counted the ones visible and not the ones that are not visible as the figure is a 3d object.

8. 6r + 5 = 4 6 - 7y -20

Rudiy27

Answer: r=-7/6y+7/2

Step-by-step explanation:

Step 1: Add -5 to both sides.

6r+5+−5=−7y+26+−5

6r=−7y+21

Step 2: Divide both sides by 6.

6r/6=-7y+21/6

Which table represents a linear function?

allsm [11]

Answer:

Graph One.

Step-by-step explanation:

See below. The graph is in a straight line, also known as linear. The other graphs are not. Also, if you look at the range (y) of the tables, you can see the increase is linear as it is increasing by .5 (1/2) everytime.

Evaluate ∫C ysin(z)ds, where C is the circular helix given by the equations x = cos(t), y = sin(t), z = t, 0 ≤ t ≤ 2π. SOLUTION

Ivahew [28]

The line integral is

$\displaystyle\int_Cy\sin z\,\mathrm ds=\int_0^{2\pi}y(t)\sin z(t)\,\sqrt{\left(\frac{\mathrm dx}{\mathrm dt}\right)^2+\left(\frac{\mathrm dy}{\mathrm dt}\right)^2+\left(\frac{\mathrm dz}{\mathrm dt}\right)^2}\,\mathrm dt$

We have

$x=\cos t\implies\dfrac{\mathrm dx}{\mathrm dt}=-\sin t$

$y=\sin t\implies\dfrac{\mathrm dy}{\mathrm dt}=\cos t$

$z=t\implies\dfrac{\mathrm dz}{\mathrm dt}=1$

so the integral reduces to

$\displaystyle\int_0^{2\pi}\sin^2t\sqrt{(-\sin t)^2+\cos^2t+1^2}\,\mathrm dt=\frac{\sqrt2}2\int_0^{2\pi}(1-\cos2t)\,\mathrm dt=\boxed{\frac\pi{\sqrt2}}$
