Menjawab:
[(√1-p²) -3√p] / 2
Penjelasan langkah demi langkah:
Dari identitas trigonometri, pemuaiannya benar:
Cos (A + B) = cosAcosB-sinAsinB
Menerapkan ini dalam memperluas cos (x + 60).
cos (x + 60) = cosxcos60 - sinxsin60
Jika sinx = p = berlawanan / sisi miring
opp = p, hyp = 1
adj² = 1²-p²
adj = √1-p²
Cos (x) = adj / hyp = √1-p² / 1
Cos (x) = √1-p²
Cos60 = 1/2 dan sin60 = √3 / 2
Mengganti nilai-nilai ini ke dalam rumus
cos (x + 60) = cosxcos60 - sinxsin60
cos (x + 60) = √1-p² (1/2) - p (√3 / 2)
cos (x + 60) = (√1-p²) / 2 - √3p / 2
Temukan KPK tersebut
cos (x + 60) = [(√1-p²) -3√p] / 2
Oleh karena itu cos (x + 60) = [(√1-p²) -3√p] / 2
Try subtracting first there were 10 then four were sold I don't know what happens after but thats what I know
Answer:
y=1/2x-3

Answer:
"No Solution"
Step-by-step explanation:
We can use the log property shown below to simplify this:
Since no "base" is given, we take base as "10" and use property to write:
Now, we solve for x:
But we are NOT done. We have to take the value and put it into the equation to check if there is any NEGATIVE value, because we cannot take negative log.
Putting in LHS:
Log(2x - 7)
Log(2(-3) - 7)
Log(-6-7)
Log(-13)
This can't be solved. So x = -3 is not a solution. Thus, there is NO SOLUTION to the equation given.
