Remark
I like to work from the original equation.
Givens
T = 2.2 seconds
pi = 3.14
L = ??
Substitute and Solve
T = 2*pi*sqrt(L/32) Find the value of 2*pi
2.2 = 2*3.14* sqrt(L/32)
2.2 = 6.28 * sqrt(L/32) Divide both sides by 6.28
2.2/6.28 = sqrt(L/32)
0.35032 = sqrt(L/32) Square both sides.
0.122723 = L/32 Multiply both sides by 32
0.122723 * 32 = L
L = 3.927 feet. <<<<< Length pendulum creating 2.2 seconds.
The answer should be B. 36 sq units hoped this helps :)
Multiplying binomial and polynomials can be easy as long as you follow the steps for example:
Let's say you were multiplying 3x-3 and x+2
(3x-3)(x+2)
remember FOIL
OR think about it like this(see attatchment)
3x^2 + 3x -6 is what you should get
Answer:
5 meters
Step-by-step explanation:
We should derive an equation to solve this problem.
Let's assign x to width and y to length.
and
so
Width = 5 meters
