Answer:
Step-by-step explanation:
Use the half angle formulas
sin(θ/2) = ±√((1 - cosθ)/2)
sin(θ/2) = ±√((1 - (3/5))/2)
sin(θ/2) = ±√((2/5)/2)
sin(θ/2) = ±√(1/5)
knowing θ is in the 4th quadrant, θ/2 will be in the second quadrant where sines are positive.
sin(θ/2) = +√(1/5) = √0.2

The interval for which the average rate of change of f(x) is negative is; from x = 0 to x = 2.5.
For the average rate of change of f(x) to be negative, it means that the change in y and the change in x must have opposite signs.
For example, if the change in y is negative, them the change in x must be positive.
Similarly, if the change in y is positive, then change in x must be negative.
Now, the graph showing this quadratic function is missing and so i have attached it.
From the graph, the only interval at which the rate of change for y and x have opposite signs is from x = 0 to x = 2.5.
In this interval, we see that x is increasing from 0 to 2.5 which is positive change while y is decreasing from 1 to -3 which is negative change.
