Suppose z varies directly with x and inversely with the square of y. If z = 18 when I = 6 and y = 2, what is z when I 7 and y =

madam [21]

It is given that z varies directly with x and inversely with the square of y so it follows:

$z=k\frac{x}{y^2}$

It is also given that z=18 when x=6 and y=2 so it follows:

$\begin{gathered} 18=k\frac{6}{2^2} \\ k=\frac{18\times4}{6} \\ k=12 \end{gathered}$

So the equation of variation becomes:

$z=12\frac{x}{y^2}$

Therefore the value of z when x=7 and y=7 is given by:

$\begin{gathered} z=\frac{12\times7}{7^2} \\ z=\frac{12}{7} \\ z\approx1.7143 \end{gathered}$

Hence the value of z is 12/7 or 1.7143.

(4xy+x^2y+4)(xy+y^2)

marysya [2.9K]

If I read this right, the answer should be $x^{2y+4}y^{2}+x^{2y+5}y+4x^{2}y^{2}+4xy^{3}$ .

Hope that helped!!
