Answer:
420
Step-by-step explanation:
if we add 30 to each of the length of speech, we get 420 seconds
Answer:
Step-by-step explanation:
We can start solving this problem by doing a drawing of London Eye. (See attached picture).
From the picture, we can see that the tourists will start at the lowest point of the trajectory, which means we can make use of a -cos function. So the function will have the following shape:
where:
A=amplitude
= angular speed.
t= time (in minutes)
b= vertical shift.
In this case:
A= radius = 67.5 m
where the frequency is the number of revolutions it takes every minute, in this case:
so:
and
b= radius, so
b=A
b=67.5m
so we can now build our equation:
which can be factored to:
You can see a graph of what the function looks like in the end on the attached picture.
Answer:
-2
Step-by-step explanation:
The perpendicular equation that passes through the point would be:
y = 1/3x + 2
To find a mixed number, take just divide the numerator by the denominator.
36/11 = 3 (with three remaining)
3 is the whole number, and if there's any remaining, put it in the numerator. So the answer is 3 3/11
Hope this helps! :)
