Answer:
1/2 + 1/2 = 1
1/4 + 1/4 = 1/2
So you would walk 1/2 mile in 1 hour
Answer:
The amplitude is 3 and the period is 10π/9.
Step-by-step explanation:
The standard cosine function is in the form:
Where |<em>a</em>| is the amplitude, 2π/<em>b</em> is the period, <em>c</em> is the phase shift, and <em>d </em>is the vertical shift.
We have the function:
We can rewrite this as:
Therefore, <em>a</em> = 3, <em>b</em> = 9/5, <em>c</em> = 0, and <em>d</em> = 0.
Hence, our amplitude is |3| = 3.
Our period will be:
Well, we can set up these equations like this-
Deborah- 2+3w
Kai- 12+2w
w=number of weeks that pass
Now, we set them equal to each other:
2+3w=12+2w
Solve for w
2-12=2w-3w
-10 = -1w
w = 10
10 weeks. Hope this helped!
