Answer:
2
Step-by-step explanation:
We should put π in place of [tex]\theta[/tex] and 6 in place of [tex]h(\theta)[/tex] in the equation given and then do algebra to find the value of [tex]a[/tex]. Steps are shown below:
[tex]h(\theta)=aSin(\theta-\frac{\pi}{2})+4\\6=aSin(\pi-\frac{\pi}{2})+4\\6=aSin(\frac{\pi}{2})+4\\6=a(1)+4\\6=a+4\\a=6-4\\a=2[/tex]
The answer is 2
Note: the value of [tex]Sin(\frac{\pi}{2})[/tex] is 1
