The length of time ( T ) in seconds it takes the pendulum of a clock to swing through one complete cycle is given by the formula T = 2 π √ L 32 Where L is the length, in feet, of the pendulum, and π π is approximately 22/7 . How long must the pendulum be if one complete cycle takes 1.5 seconds? In feet

the first one

step-by-step explanation:

just id the test.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
