Answer:
d = 3 meters
Step-by-step explanation:
d = rt where d is the distance t is the time and r is the constant of proportionality
d = 18t
Changing 10 minutes to hours
10 minutes * 1 hours / 60 minute = 1/6 hour
d = 18 * 1/6 hour
d = 3 meters
Velocity
Formula wise:
1/2 x mass x velocity^2
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:
B
Step-by-step explanation:
8/33 = 0.24242424 ...
so 6.24 repeating = 6 8/33 which is rational. It can be represented by
206/33 which is a fraction and hence rational
(2x + y)³
(2x + y)(2x + y)(2x + y)
(2x(2x + y) + y(2x + y))(2x + y)
(2x(2x) + 2x(y) + y(2x) + y(y))(2x + y)
(4x² + 2xy + 2xy + y²)(2x + y)
(4x² + 4xy + y²)(2x + y)
4x²(2x + y) + 4xy(2x + y) + y²(2x + y)
4x²(2x) + 4x²(y) + 4xy(2x) + 4xy(y) + y²(2x) + y²(y)
8x³ + 4x²y + 8x²y + 4xy² + 2xy² + y³
8x³ + 12x²y + 6xy² + y³
