Step-by-step explanation:
4 is the A or Ampltiude
To find the period set it equal to 2 pi/B


b=

b=

There is no phase shift
The midline or d or vertical shift is 1.
Our equation for 8 is

9.Use sin function. The a value is 2 or -2 your choice.
Set up the period equal to the equation



Which equal 6.
B=6
There is no C and the D and Vertical Shift is 1.
Our equation is

Associative property of addition represents this equation:
a + b = b + a
So, how would it be helpful with this given equation?
=> 48 + 82
=> Let's start with the ones place value.
(2 + 8) = 10, bring down 0, carry 1 then ( 4 + 8) = 12 + 1 = 13
So the answer is 130.
If we are going to do it vice versa, still expect that the same answer will occur.
(s + 3t) * (2s - 2t) = 2s^2 - 2st + 6ts - 6t^2
