F (g (x))= 2/(2/x)
=2×(x/2)
=x
g (f (x))=2/(2/x)
=2 (x/2)
=x
f and g are inverses functions
To solve this problem you must apply the proccedure shown below:
1. You have that t<span>he largest doll is 12 inches tall. The height of each of the other dolls is 7/10 the height of the next larger doll. Therefore, you have:
We don't know the number of dolls, so:
x=12(7/10)^(n-1)
Where x is the height of the doll and n is the number of the doll
The answer is: </span>x=12(7/10)^(n-1)
Answer:
D
Step-by-step explanation:
The formula for volume of cone is 
Where
V is the volume
r is the radius of the circular base
h is the height of the cone
<em>In the diagram shown, we can clearly see that height is 12, radius is 9. We can simply plug them into the formula and get our exact answer (leaving pi as pi):</em>

<em>correct answer is D</em>
Answer:
TZ = 10 units
UY = 12 units
ZW = 11 units
Step-by-step explanation:
Point Z is the centroid of ΔTUV.
Since, centroid of a triangle is located on each median so that it divides each median in the ratio of 2 : 1
Therefore, TZ = 2(ZX)
TZ = 2(5) = 10 units
UY = UZ + ZY
= UZ + 
= 
= 
= 12 units
ZW = 
= 
= 11 units
