A sinusoidal function whose period is π/2 , maximum value is 10, and minimum value is −4 has a y-intercept of 3. What is the equation of the function described?

Step-by-step explanation:

The sinusoidal function has a general form of:

The period is given by:

Y is the y-intercept, thus y = 3.

At the maximum value:

At the minimum value:

Therefore, the equation of the function described is:

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
