The average speed of a train that travels x miles in 3/4 hour

Mathematics
1 answer:
Dennis_Churaev [7]3 years ago
5 0

Answer:

Average speed of train = 4x/3 miles per hour

Step-by-step explanation:

A train travels x miles in 3/4 hours

Let's find the distance train travels in 1 hour.

i.e distance travel in one hour = x /(3/4)

or distance travel in one hour = 4x/3

So,

Average speed of train = distance / time

Average speed of train =  ( 4x/3 / 1 )

Average speed of train = 4x/3 miles per hour

Given that f(x) = x2 + 5x + 6 and g(x) = x + 2, find (fºg)(x) and
PolarNik [594]

Answer:

(f\circ g)(x)=x^2+9x+20

Step-by-step explanation:

We have the two functions:

f(x)=x^2+5x+6\text{ and } g(x)=x+2

And we want to find:

(f\circ g)(x)

This is equivalent to:

(f\circ g)(x)=f(g(x))

Therefore, we will have:

f(x+2)

By substitution:

f(x+2)=(x+2)^2+5(x+2)+6

Simplify. Square and distribute:

f(x+2)=(x^2+4x+4)+(5x+10)+6

Rearrange:

f(x+2)=(x^2)+(4x+5x)+(4+10+6)

Combine like terms:

f(x+2)=(f\circ g)(x)=x^2+9x+20
