Answer-
The rider’s displacement during this time is 17.01 m
Solution-
As we know,
Where s = displacement,
u= initial velocity = 0, as the rider starts from rest
a= acceleration = 0.5 m/s²
t= time taken = 8.4 s
Putting the values,
Answer:
Combination
Step-by-step explanation:
Here by 10C7 we actually mean,
And the formula for evaluating mCn is
Therefore
10C7 =
Where m! is called m factorial and can be evaluated as
m!= m*(m-1)*(m-2)*(m-3)*.......3*2*1
Hence
10!= 10*9*8......*3*2*1
7!= 7*8*6.....3*2*1
3!=3*2*1
With these we can evaluate
10C7
Hence the answer is D
