1.
km=kilometers
kilo=1000
1 km=1000meters
so
1/2km= 1/2 times 1000=1000/2=500meters

2. 1/4 km=1000/4=250 meters

3. 1/5 km=1000/5=200 meters

4. 2/5 km=2000/5=400 meters

5. 3/4 km=3000/4=750 meters

6. 1/8 km=1000/8=125 meters

Which of the following is an odd function?

Inga [223]

Answer:

f(x)=-x

Step-by-step explanation:

An odd function is symmetric with respect to origin.

It has the property,

$f( - a) = - f(a)$

The only function that is symmetric about the origin is:

$f(x) = - x$

Now let's put x=-a, to get:

$f( - a) = - - a = a$

Also

$f(a) = - a$

We can see that:

$f( - a) = - f(a) = a$
