A fraction is numerator over denominator, most of the time whole numbers
Answer:
Option B, -1/2
Step-by-step explanation:
<u>The slope is change in y over change in x.</u>
<u />
<em>Since this line is facing downward, we already know that the slope is negative.</em>
<em />
<u>To find the ratio, find the change in y and divide the change in x.</u>
<em>Change in y = -1</em>
<em>Change in x = 2</em>
<em />
<u>Change in y over change in x:</u> <em>-1/2</em>
Answer: Option B, -1/2
Answer:
4Hz
Step-by-step explanation:
Standard form of a sine or cosine function,
y = acos(b(x+c))
where a is the amplitude, b is the value to find the period. and c is the phase shift.
Period = \frac{2\pi}{b}
From the equation given in the question,

We can see:
Amplitude = 3,
Period = \frac{2\pi}{8\pi} = 1 / 4
Phase Shift = 1 / 16
Now we want to find the frequency.
Frequency = 1 / Period
= 1 / (1/4)
= 4Hz
