Jelaskan pake rumus yh. please master.... Question from @parlinsianipar

5dregensleyer Panjang CB = ?
$$\begin{align} cb &= \sqrt{34^{2} - 16^{2} }\\ &= \sqrt{1156-256} \\ &= \sqrt{900} \\ &= 30\ cm \end{align}$

panjang EB =?
$$\begin{align} \frac{cb}{bd} &= \frac{ab}{eb} \\ \frac{30}{45} &= \frac{16}{eb}\\ 30eb&= 720 \\ eb &= \frac{720}{30} \\ eb &= 24 \cm \end{align}$

panjang CE
CE = CB - EB
= 30 - 24
= 6 cm

jawabnnya B

romayuli05 BC = akar ( AC)^2 - ( AB)^2
      = akar ( 34)^2 - (16)^2
      = akar ( 1156 - 256)
       = akar 900
   = 30 cm

BC / BD = AB /BE
30 / 45 = 16 / BE
BE = (45 x 16 )/ 30 = 24 cm

jika panjang BC = 30
sedangkan BE = 24
maka pangkang EC = BC -BE = 30 - 24 = 6cm

romayuli05 itu panjang bukan pangkang .. maaf slah ketik

MATRIKS 100 Pointyang diatas no 1) itu 4 pangkat x+2yyang no 2) 2a+b

100 PointJika f invers (k) =4 Maka Nilai k ??ps : Soal ada di gambar

F(2x+3) =x+3------2x-4 maka f(x) -1 ???

Besar arus yang mengalir dalam rangkaian diatas adalah ... amperekiri = 12VAtas= 8OhmKanan atas= 11 OhmKanan Bawah = 5 Ohm

F(x) = 3²x-¹ maka tentu kan inversnya

F(x) =² log (3x-4). maka tentukan inversnya
