-1 is greater then 1.05 then 1.05 then 1.55
so the answer is C
In the standard form of the equation
![\\ \ f(t)=Acos[b(t\pm c)]+k\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%5C%20f%28t%29%3DAcos%5Bb%28t%5Cpm%20c%29%5D%2Bk%5C%5C%20%5C%5C%20)
The middle line =k
For our given problem
f(t) = 40cos (80t + 20)
On comparison we get k=0
Hence middle line=0
Answer: 18
Step-by-step explanation:
Square root of 81 is 9 because 9*9=81 then 9*2=18
First let's find out the total number of strikeouts, by adding the number of strikeouts of each person:

Now, to find the percentage of strikeouts that Samar is responsible, let's divide his number of strikeouts (5) by the total number of strikeouts (50):

So Samar is responsible for 10% of the strikeouts.
The answer will be 7x^2 + 5x
