Answer
the first one is 2/3 and the second is 1/4 the other i'll comment a little later
Step-by-step explanation:
Answer:
D. 0.65
Step-by-step explanation:
0.20 + 0.15 + 0.30
= 0.65.
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
Answer:
x=-3
y=3
(-3-3i)(3+5i)
Step-by-step explanation:
![(x-yi)(3+5i)\\=3x+5xi-3yi+5y\\=(3x+5y)+(5x-3y)i\\](https://tex.z-dn.net/?f=%28x-yi%29%283%2B5i%29%5C%5C%3D3x%2B5xi-3yi%2B5y%5C%5C%3D%283x%2B5y%29%2B%285x-3y%29i%5C%5C)
and we have that must equal
6-24i
3x+5y=6
5x-3y=-24 and if we work it we found out that the solutions are
x=-3 and
y=3
$72,00?
I'm assuming you are saying $7200, but if you are saying $72, just replace.
6% = 0.06
7200 / 0.06 = 432
So you would get $432. But trust me, no house is that cheap lol
