If we start at the point (1,0) and travel once around the unit circle, we travel a distance of 2 pi units and arrive back where

PolarNik [594]

Answer:

-1

Step-by-step explanation:

We evaluate $\sin(2\pi+3\pi/2)$

In $2\pi+3\pi/2$ , $2\pi$ is a complete revolution and is the same as 0. So we have

$\sin3\pi/2 = \sin(\pi+\pi/2)$

One $\pi$ is a half revolution, putting the point at (-1, 0). $\pi/2$ is a quarter of a revolution. A quarter circle from (-1, 0) anticlockwise is (0, -1).

The sine is the y-coordinate of a point along a unit circle.

Hence, $\sin(2\pi+3\pi/2)=-1$

Solve V = 1/3πr2h for h.

Rashid [163]

Step-by-step explanation:

v=1/3nr2h for h

3(v)=3(1/3nr2h)

3v/2nrh=2nrh/2nr

3v/2nrh=h

h = 3v/2nrh

ELEN [110]

Answer:

Option D) 340

Step-by-step explanation:

We are given the following in the question:

Alpha, α = 0.05

Population standard deviation, σ = $47

Margin of error = 5

95% Confidence Interval:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

$\text{Margin of error} = z_{critical}\frac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

$5 = 1.96(\dfrac{47}{\sqrt{n}} )\\\\\sqrt{n} = \dfrac{47\times 1.96}{5}\\\\n = 339.443776\\\Rightarrow n \approx 340$

Thus, the correct answer is

Option D) 340
