Problem 1
<h3>Answer: D) 2pi</h3>-------------------
Explanation:
The given table we have is
If you were to graph all those points and draw a cosine curve through them, then the function you should get is
The B coefficient is 1, so that leads to a period of
T = 2pi/B
T = 2pi/1
T = 2pi

Problem 2
<h3>Answer: C) 343.134 yards</h3>-------------------
Explanation:
Draw out a triangle with these properties
- side a = 270
- side b = 170
- angle C = 100
We'll use the law of cosines to find side c
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 270^2 + 170^2 - 2*270*170*cos(100)
c^2 = 117740.902710
c = sqrt(117740.902710)
c = 343.133943
c = 343.134

Problem 3
<h3>Answer: A) 2</h3>-------------------
Explanation:
If you started with y = sin(x) and applied the transformations stated, then you should end up with
From here, plug in x = 0 to find the y intercept.
