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

Answer:
1 hour and 50 minutes will take to fill up a 300 gallon swimming pool explanation just do the quation/math
S = rθ
4.2 = 1*θ
The central angle (θ) is 4.2 radians.
16 = 4²
So, by the definition of logarithms

Find two pefect lines that touches the middle then do rise over run and that will be your slope
