Answer:

y=4\sin(\frac{3}{2}x+\frac{2\pi}{3})

Step-by-step explanation:

The graph of the cosine function can be obtained by shifting the sine function to the left by \frac{\pi}{2} units.

The given cosine function is:

y=4\cos(\frac{3}{2}x+\frac{\pi}{6})

When we shift this function to the left by \frac{\pi}{2} units, we obtain a sine function

y=4\sin(\frac{3}{2}x+\frac{\pi}{6}+\frac{\pi}{2})

y=4\sin(\frac{3}{2}x+\frac{2\pi}{3})

These two functions have the same graph

The second option is correct.

Anyone know how to answer this? Help if u do please!
Inga [223]
A- It will be smaller, because we're finding a part of a number, and it's no more than 100 percent.
B- It would be greater. It's more than 100 percent, which accounts for the whole value, and goes even more.
Hope this helps!

An object travels along a circular path so that it completes one revolution in 8 seconds. If the linear velocity of the object i
natima [27]

Answer:

Using the concept of speed-distance-time, we find that the diameter of the circular path is 12 inches.

Step-by-step explanation:

Given that the object completes one revolution in 8 seconds. So, the circular speed of the object is 2πr/8 = πr/4 inches per seconds, where r is the radius of the circular path. The speed can be written as:

πr/4 inches per seconds = 60πr/4 inches per minute = 15πr inches per minute.

But, it is given that the circular speed of the object is 90π inches per minute. So,

90π = 15πr

r = 6 inches

Since, diameter is the double of radius, d = 2r = 12 inches.
