Answer:

41.883

Step-by-step explanation:

c^2 = 29^2 + 13^2 - 2(29)(13)(cos 41)

c^2 = 841 + 169 - 754(-0.987)

c^2 = 1010 + 744.198

c^2 = 1754.198

c = 41.883

(fog)(x). F(x)=3x, g(x)=x+7
ivann1987 [24]

For this case we have the following functions:

f (x) = 3x\\g (x) = x + 7

We must find (f_ {0} g) (x). By definition we have to:

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

So:

f (g (x)) = 3 (x + 7) = 3x + 3 * 7 = 3x + 21

Finally, the composite function is:

(f_ {0} g) (x) = 3x + 21

Answer:

(f_ {0} g) (x) = 3x + 21
