The given sequence is:
a(2)=1
a(3)=3
a(4)=9
We are to find the average rate of change between n=3 and n=4 for the given function.
Average rate of change =
So the average rate of change for the given function from n = 3 to n = 4 is 6
Answer: Stratified sampling
Step-by-step explanation:
Stratified sampling is a random sampling method in which the population is divided into non-coinciding groups are called strata and a sample is picked out by some design within each stratum.
Given: A researcher wants to survey people from different age groups to analyze voting patterns.
Thus he will make different groups according to different ages to analyze voting patterns that are called stratum.
Thus, Stratified sampling best accomplish this goal.

Answer:
Acceleration of the particle = 
Step-by-step explanation:
We are given the position vector of a particle moving in a circle of radius b units.
r(t) = b cos(ωt)i + b sin(ωt)j
Velocity , v =
= -bω sin(ωt)i + bω cos(ωt)j
The magnitude of velocity, v =
Squaring both sides,
Since 
= 1
The acceleration towards the centre is called the centripetal acceleration and is given by
a = 
a = 
a =
