Alright well basically I've got 2 problems, haven't done algebra in a year, totally forgot how to do this stuff.
√x/y =4 , which of the following represents y in terms of x?
a. y = x/2
b. y = 2/x
c. y = x/16
d. y = 16/x
problem number 2
The forumla P = 2pi (√L/32) can be used to approximate the period of a pendulum,
Where L is the pendulum's length in feet and P is the pendulum's period in seconds. If a pendulum's period is 1.6 seconds, what is the length of the pendulum to 3 decimal places?
I'd appreciate explanation with the answer please, thank you.
