6*5= 30 fingers, so tim would say there are 30 fingers.
"Rate of change" is another name for "slope".
In the table, every time 'x' increases by 2, 'y' also increases by 2.
So the rate of change (slope) of the function in the table is
(change in 'y') / (change in 'x') = 2/2 = 1 .
The rate of change (slope) in the function y = x + 4 is
the coefficient (number before) the 'x'. That's also ' 1 '.
So t<span>he rate of change in the function y = x + 4 is the same as (equal to)
the rate of change of the function represented in the table.</span>
The series in the form of arithmetic progression
The notation of A.P is a, a+d, a+2d.....
The summation notation is â‘
In this series a=3, d=7
Then the summation of A.P is â‘ = n/2(2a+(n-1)d)
=18/2(2*3+ (18-1)7)
= 9(6+17(7))
=9(6+119)
=9(125)
= 1125
Hence the total number of beads is 1125
Sure with what? u should have asked ur question
