Recall that:
sin(A + B) = sinAcosB + cosAsinB
Therefore:
sin11°cos19° + cos11°sin19° = sin(11° + 19°)
= sin30° = 0.5
I hope this explains it.
Answer:
V=2
Step-by-step explanation:
For the inverse variation equation p = StartFraction 8 Over V EndFraction, what is the value of V when p = 4?
P=8/V
Inverse variation is expressed as
y=k/x
Where,
k= constant.
From the question,
P=8/V
Where,
8=constant
What is the value of V when p=4
P=8/V
Make V the subject of the formula
pV=8
V=8/p
Substitute the value of p
V=8/4
V=2
