The period of a pendulum is the time the pendulum takes to swing back and forth. the function upper l equals 0.81 t squared relates the length l in feet of a pendulum to the time t in seconds that it takes to swing back and forth. a convention center has a pendulum that is 50 feet long. find the period.

It is given that the time period of a pendulum(T) is the time(t) the pendulum take to swing back and forth.

Given the function:         ......[1]

where L is the length in feet of a pendulum and t is the time in second.

It is given also, a convention center has a pendulum (L) = 50 ft long.

Substitute the value of L in [1] to solve for t;

Divide both sides by 0.81 we get;

Simplify:

or

sec

therefore, period of pendulum (T), is 7.86 sec (nearest to hundredths)

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
