This is a physics question.
Use the formula for simple pendulum:
T = 2π √(L/g)
Where T is the period (time to complete a full oscilation), L is the lenght and g acceleration of gravity ≈ 9.81 m/s^2 .
So, solve for l:
√(L/g) = T / (2π)
L = [T / (2π) ] ^2 * g = [ 6.0s / (2π) ]^2 * 9.81 m/s^2 = 8.9 m
Answer: 8.9 m
The area of a parallelogram is base x height, or A = bh.
a) A = 6 x 10, so A = 60 cm²
b) A = 15 x 8, so A = 120 cm²
Y=mx+c
Parallel=> m=5
Y=5x+c
Sub (1,6)
6=5+c
=> c=1
=> equation is y=5x+1
To combine like terms and single out one term to take it easier to solve, the 6x was moved to the other side to combine like terms.
Subtracting 6x from 10x which is 4x
Answer:
Both -1.5 and -3/2 will be halfway between -2 and -1 on the number line. 3/2 will be halfway between 1 and 2. -4/3 will be between -1.5 and -1.
