Alright, since these are multiplied, we can cross off the x to the power of n's. After that, we have x^2/x^3, and we can subtract 3 from 2 to get x^(-1), or 1/x
since it states that they hired 2 buses
and the equation is coming up with the total number of students ,
the letter b is for the number of students that rode each bus
We are given
A dog runs from point O to B
t(OA)=2.3 s
t(OC)=4.1 s
now, we can find time between A and C
t(AC)=t(OC)-t(OA)
t(AC)=4.1-2.3
t(AC)=1.8 s
we are given
distance between A and C is 4m
so,
d=4m
now, we can find average velocity between A and C
we can plug values
so, option-C..................Answer
Answer:
Given a function f(x), for determining in what intervals the function is increasing (or decreasing) you can calculate its derivative f'(x) and put it greater than 0 (or smaller than 0). It will give you some intervals.
