Answer: Second option.

Step-by-step explanation:

Given the function f(x), which is:

f(x)=x

And given the function g(x), which is:

g(x)=2

You need to substiute the function g(x)=2  into the function  f(x)=x in order to find (fog)(x).

Therefore, through this procedure, you get this answer:

(fog)(x)=(2)

(fog)(x)=2

You can observe that this matches with the second option.

For this case we have the following functions:

f (x) = x\\g (x) = 2

We must find (f_ {0} g) (x).

By definition of composite functions we have to:

(f_ {0} g) (x) = f (g (x))

We substitute g (x) into f (x), then we have:

f (g (x)) = 2

Answer:

f (g (x)) = 2

Can somebody please help me?
ElenaW [278]
 <span>for the first part, realize that the hour and minute hands are moving at different rates; in one hour, the minute hands moves all the way around the face of the clock, and thus moves a total of 360 degrees or 2 pi radians; the hour hand moves only 1/12 away around the clock, so covers only 30 degrees or Pi/6 radians. 

Now, the LINEAR distance traveled by the tip of each hand is also determined by the length of the hand. In the case of the minute hand, it sweeps out a circle of radius 10 cm, so traces out a circle of radius 10 cm. Since the circumference of a circle is 2*pi*r, the minute hand (remember it made one complete cycle) covers a distance of 2*pi*10cm=20 Pi cm 

The hour hand covers only 1/12 a circle, but that circle is only 6 cm in radius, so the distance traveled by the tip of the minute hand is: 

1/12 *[2 *pi*r]=1/12*[12*pi]=pi 

so the difference is 19pi 

for the last part, you should draw a diagram of the two hands, the minute hand is 10 cm in length, the hour hand is 6 cm in length, and they are 30 degrees apart...from that drawing, see if you can figure out the remaining leg of the triangle you can form from them 

good luck</span><span>
