Hi all, Im having trouble with this question:
A chain hangs so that its shape is of the form y=56ch(x/56).
Determine correct to 4 SF
a) the value of y when x is 35
I simply plugged this into the calculator and got the answer 67.29
b) the value of x when y is 65.
Im not sure how i rearrange the equation or what to do really at all.
