Question

2. If z is inversely proportional to w and z = 9 when
w = 9
(i) find an equation connecting w and z,
(ii) find the value of z when w = 16,
(iii) calculate the value of w when z = 3.​

Answer 1

Step-by-step explanation:

z=k/w , where k is constant.

9=k/9, k=81

(i)equation is zw=81

(ii)z=81/16

(iii) w=27
