Question

Wyznacz z wzorów podane litery.

y = a + 2ax (a)

i = a/2 + 2/k (k)

a = b/3 + 3/k (k)

Legenda:

1/2 = jedna druga

(q) = wyznacz literę w nawiasie

Answer 1

/ -dzielenie

a)

y=a(1+2x) /:(1+2x)

y/(1+2x) = a

a = y/(1+2x)

b)

i-a/2=2/k /*k

k(i-a/2)=2 /:(i-a/2)

k=2/(i-a/2)

c)

a-b/3=3/k/*k

k(a-b/3)=3/:(a-b/3)

k= 3/(a-b/3)
