First, put the equation of the line giveninto slope-intercept form by solving fory. You get y = 2x +5, so the slope is –2.Perpendicular lines have opposite-reciprocal slopes, so the slope of theline we want to find is 1/2. answer y=-1/2

<u>The Cosine Function</u>
The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:

Both the amplitude A and the angular frequency w of a cosine can be modeled by the function

The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:

Thus:

Therefore, the equation of the sinusoid is:

Answer: C
Answer:
A. 8n-10
Step-by-step explanation:
8n2−26n+20/n−2
=2(4n−5)(n−2)/n−2
=8n−10
