PLZ HELP ASAP
I am struggling with this unit
1. Find sin0 is cos0 = 1/2 and 0 terminates in quadrant IV.
2. Find cos0 if sin0 = sqrt2/2 and 0 terminates in Quadrant I.
3. Find tan0 if cos0 = -1/2 and 0 terminate in Quadrant II.
4. Find tan0 if sin0 = -1 and 0 is less than or equal to 0 < 2 pi radians radians.

c. histogram

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
