Answer:
Step-by-step explanation:
We know for a function:
y = Asinωt
=> on comparison, <u>A = 5 m</u>
=> T = 2π / ω
=> T = 2π / 2
=> <u>T = π seconds</u>
Answer:
255 steps
Step-by-step explanation:
They give us the length of the bridge and the length of each step of Robert, therefore we must divide these values to find the number of steps necessary, but first we must pass the distance of the bridge to centimeters:
140m * 100cm / 1m = 14000
Therefore the bridge would have a length of 14000 centimeters, we divide:
14000/55 = 254.54
Which means that Robert take at least 255 steps to fully walk the bridge.
The solution is x=-3, y=1, z=-1
Answer:
18 days
Step-by-step explanation:
Let x represent number of days.
We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall 
seconds behind in x days.
We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total 
seconds in x days.
Since Brady's watch is 22 seconds behind, so we will equate by 22 to solve for x as:
Therefore, Brandy set her watch 18 days ago.
