Question

X varies directly with Y and inversely with the square of Z for x=2,y=3, the value of z is 8, find x, for y=6 and z=2​

Answer 1

Step-by-step explanation:

when z varies directly proportional to x means a division

c

=

z

x

where c is a constant of proportionality

when z varies inversely proportional to x it means a product

z

y

=

c

now with both

k

=

z

y

x

z

=

8

;

x

=

12

and

y

=

3

k

=

8.3

12

k

=

2
