Answer:

The farthest distance would be 32.5 miles

Step-by-step explanation:

Given,

Speed = 65 miles per hour,

If t represents the time ( in hours ) taken in travelling,

Since, time has to commute down less than 30 minutes,

Also, 1 hour = 60 minutes,

$\implies 1\text{ minute}=\frac{1}{60}\text{ hour}$

$\implies 30\text{ minutes}=\frac{30}{60}=\frac{1}{2}\text{ hour}$

Thus,

$t\leq \frac{1}{2}$

i.e. the highest time taken = 1/2 hours,

We know that,

Distance = speed × time,

∵ Distance ∝ time,

⇒ Distance will farthest for largest time taken,

Hence, the farthest distance = $65\times \frac{1}{2}$ = 32.5 km.

Select the correct answer.<br> Find the Inverse of function A<br> F(x)=1/3 -1/2x

kompoz [17]

Answer:

If you actually meant f(x)=2x+3x−1 ,

then note it can be rewritten as:

f(x)=2x−2+5x−1=2+5x−1=y

At this point you can find x in terms of y (“make x the subject”):

y−2=5x−1⟹1y−2=x−15

⟹x=5y−2+1=y+3y−2

Switch variables back to x, and you have the inverse function of f:

g(x)=x+3x−2

How do you know you’ve calculated correctly? The composition of f with g should result in x — that is, evaluate f(g) and you should get the result x:
