Answer:
Step-by-step explanation:
m (x) = (x+ 5) / (x -1) and n(x) = x - 3.
Hence
but n is a function and n = x-3. Now, replace value of n on m (n)
simplify it
since (m . n) (x) is a fraction function, its domain will be all x such that the denominator is NOT 0. That is
among options, only C has the same denominator with
Hence their domains are the same.
Answer:
The time it takes for the pendulum to swing from its rightmost position to its leftmost position and back again is 1.25 seconds.
Step-by-step explanation:
Given the equation
-----------Equation 1
where d, in inches of the pendulum of a grandfather clock from the center.
Comparing with the standard equation of an oscillating pendulum bob.
----------Equation 2
where ω = angular velocity
t = time taken
α = The angular displacement when t = 0
Comparing equation 1 and 2,
α = 0
Recall that [/tex]
f = 0.8 Hertz
Recall that
T = 1.25 seconds
Therefore, the time it takes for the pendulum to swing from its rightmost position to its leftmost position and back again is 1.25 seconds.
