Find the period, range, and amplitude of the cosine function y= 3/2cos t/2

Mathematics
1 answer:
Rudik [331]3 years ago

Answer:

Amplitude = /\frac{3}{2}/

Range = [\frac{-3}{2} , \frac{3}{2}]

Period = \pi

Step-by-step explanation:

Given: y = \frac{3}{2}cos\frac{t}{2}

Comparing the equation with the standard form of cosine function :

y = A cos(Bx- C)

where:

A = Amplitude

Formula for calculating Amplitude is given as:

Amplitude = /A/

The formula for calculating Period is given as :

Period =\frac{2\pi }{B}

B = \frac{1}{2}

Therefore , with the comparison

A = /\frac{3}{2}/

which means that:

Range = \frac{-3}{2} , \frac{3}{2}

Period = \frac{2\pi }{2}

Period = \pi

Rudiy27
The second showing had begun at 5:25. And there had been a 1/2 hour (30 minutes) break before it. So we substract this break from 5:25 and we get 4:55 - the time when the first showing had ended. 

So the first showing had begun at 2:30 and had ended at 4:55. By substracting 2:30 from 4:55 we get 2:25 - that's the duration of the video.

The answer is 2 hours and 25 minutes.
