Xis inversely proportional to y. x is directly proportional to z squared. when y = 4, x = 5.5. work out the value of x when y = 5.

4.4

Step-by-step explanation:

X is inversely proportional to y, so x = k/y where k is just a constant.

X is directly proportional to z squared, so x = kz^2 where k is a constant

Here, The second relationship doesn't even matter.

Plug the values for x and y into the first equation and solve for k.

5.5=k/4

k=5.5*4

k=22

Now plug k and the second y back in.

x=22/5

x=4.4

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
