Question

Y is inversely proportionate to square of x. The length, y, of a solid is inversely proportional to the square of its height, x.
The length, y, of a solid is inversely proportional to the square of its height, x.

a.) Write down a general equation for x and y.
Show that when x=5 and y=4.8 the equation becomes x²y=120.

b.) Find y when x=2.

c.) Find x when y=10

d.) Find x when y=x

e.) Describe exactly what happens to y when x is doubled

f.) Describe exactly what happens x when y is decreased by 36%

g.) Make x the subject of the formula x²y=120

Yeah, I kinda got lost at the beginning XD

Answer 1

all the questions you have asked is the same. the answers for the question except e and f are in the attachment

Answer 2

Answer:

[

Step-by-step explanation:

Make

$\frac{5}{4} = \frac{125}{100} by \: making \: the \: denominator \: = 100 \: which \: shows \: that \: value \: of \: x \: inreases \: by \: 25\% \: when \: y \: decreases \: by \: 36\%.$
