Answer:
Option b.
Step-by-step explanation:
We can easily solve this problem by using a graphing calculator or plotting tool.
The function is
h(t) = cos (t +1)
Please, see attached picture below.
By looking at the picture, we can tell that the amplitude is equal to 1
The function has a period of T = 2π
We can see there is no vertical shift.
It has a phase shift of +1. (Which moves the graph to the left)
Answer:
Option b.
Answer: 205
Step-by-step explanation:
Initially, Jill received ballots from the student council election = 45
After, dropping ballot by Mr. Alvarez, new ballots he has = 250
Hence, The Ballots drooping by Mr. Alvarez = new ballots Jill has - Initial ballots Jill has
= 250 - 45
= 205
Therefore, Mr. Alvarez drop off 205 ballots.
An=-31+(n-1)-11 find the eleventh term
a11 = -31 + (-11) (11-1)
a11 = -31 +-11(10)
a11 =-31 +-110
a11 = -142
C. multiplication (the 8 x 9 within the parenthesis)
