Three quantities x, y and z are connected so that x varies directly as z and inversely as the square root of y. If x=6 when z=12 and y=25,find the expression for x in terms of y and z

The expression for x in terms of y and z is x = or x =

Step-by-step explanation:

The relationship between x, y and z can be expressed as;

x α

x = C × , where C is a constant of proportionality

Now, given the values of x, y and z, we can have that;

6 = C ×

6 = C ×

C = 6 × = 2.5 or

Putting the value of C in the equation, we have;

x = or

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
