At what values of x does the graph of f(x)= sin x intersect the x-axis?
a) all multiples of pi/2
b) odd multiples of pi/2
c) all multiples of pi
d) even multiples of pi

c) all multiples of

Step-by-step explanation:

The given function is

The graph of this function is shown in the attachment.

We can see that the graph intersect the x-axis at

We can also solve the equation,

and obtain;

, where n is an integer.

as the x-values where the graph intersect the x-axis.

y=sec x is the correct answer

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
