Answer:
0.79 sec
Step-by-step explanation:
Given there is a tool at the top of the building which is dropped by a worker and it follows the following equation at every instant of time .
where
We know that this height is measured from the base of the building which means that when the tool reaches the bottom of the building it has h = 0 feet.
Let this be done at time t
h(t) = 0
t = 0.79 sec
Therefore the total time taken by the tool to reach the bottom of the building is 0.79 sec.
The domain of the function g(x) = 2 log₂(x - 4) + 3 will be (4, ∞). Then the correct option is A.
<h3>What are domain and range?</h3>The domain means all the possible values of x and the range means all the possible values of y.
The graph of the function f(x) = log₂x is shown.
Function g is defined as g(x) = 2f(x - 4) + 3.
Then the function g(x) will be
g(x) = 2 log₂(x - 4) + 3
Then the domain of the function g(x) will be (4, ∞).
Then the correct option is A.
