(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:

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

Given: F3 = 5 k + 515 g F4 = 945k - 713 g ; find F20

Answer:

F20 = 15985k -20361g

Step-by-step explanation:

If we assume F3 and F4 are the third and fourth terms of an arithmetic sequence, the common difference is ...

d = F4 -F3 = (945k -713g) -(5k +515g)

d = 940k -1228g

Then the 20th term is ...

F20 = F3 +(20 -3)d = (5k +515g) +17(940k -1228g)

F20 = 15985k -20361g

A tv show is on from 7:00 to 8:00pm.If there are 18 minutes of advertisements during that time,what percent of the show was adve

svetlana [45]

There are 60 minutes in an hour and percent means per one hundred so:

p/100=18/60

p=1800/60

p=30%
