Answer:
Option B is correct
Step-by-step explanation:
Given is a cos funciton.
Period = 3
Max = 20 and minimum =0
Hence centre line is y = 1/2 (max+min)
i.e. y =10 is the central line
Let the funciton be of the form
y = a cos (bx+C)+d
We got d = 10...i
Period =3
Hence b = ... ii
Amplitude = a = distance of max from central line = 20-10 =10...iii
Since reflection over x axis, sign of a =negative
a=-10
Since no horizontal shift, c=0 ... iv
Put to gether the function is
Answer:
1595
Step-by-step explanation:
The given sequence is
2, 7, 26, 101, 400, ?
We need to find the missing term in this pattern.
First term is 2.
So, the nh term of the sequence is
Substitute n=6,
To find the next term, we need to find the product of 400 and 4 and after that the difference of resultant number and 5.
.
Therefore, the missing term is 1595.
