The cylinder below has r = 10 inches and a volume of 6283 cubic inches to the nearest cubic inch. Find the height of the cylinde
kaheart [24]
V=hpir^2
r=10
v=6283

6283=hpi10^2
6283=100hpi
divide both sides by 100
62.83=hpi
aprox pi=3.141592
divide both sides by pi
19.9994143=h
so about 20 inches

Write a correct equation for the function whose graph is shown.
Rom4ik [11]

Answer:

\displaystyle y=-2sin(6t)

Step-by-step explanation:

<u>Sinusoid</u>

The shape of a sinusoid is well-know because it describes a curve with a smooth and periodic oscillation. The sine and cosine are the two trigonometric functions in which the graph matches the description of a sinusoid. The sine can be identified because its value is zero at time zero.

The graph shown in the figure corresponds to a sine. The other characteristics of the sine function are

* It completes a cycle in2\pi radians

* It has a maximum of 1 and a minimum of -1

* It's increasing for a quarter of the cycle, decreasing for half of the cycle, and increasing for the remaining quarter of the cycle

* The equation is

y=Asin(wt)

The function starts decreasing for the first quarter, which only is possible if the amplitude A is negative. We can also see the maximum and minimum values are 2 and -2 respectively. This means the amplitude is A=-2

We can also see the function completes 3 cycles in t=\pi radians or 6 cycles in 2\pi radians. Or, equivalently

wt=12\pi

w(2\pi)=12\pi

\displaystyle w=\frac{12}{2}=6\ rad/sec

Thus, the function can be expressed as

\boxed{\displaystyle y=-2sin(6t)}
