The number of lightning strikes will be a whole number
Therefore it is a discrete variable
28-24=4/2=2
The answer is 2.
Answer:
b
Step-by-step explanation:
cos(t) + i * sin(t) = e^(i * t)
Therefore, (cos(t) + i * sin(t)) / (cos(s) + i * sin(s)) = cos(t - s) + i * sin(t - s)
9 * (cos(135) + i * sin(135)) / (7 * (cos(10) + i * sin(10))) =>
(9/7) * (cos(135 - 10) + i * sin(135 - 10)) =>
(9/7) * (cos(125) + i * sin(125))
They are 3.771, 3.861 and 3.870 respectively.
The distance traveled is given by:
Where,
R: Ferris wheel radio
α: central angle
The angle for a revolution is:
Therefore, substituting values we have:
Answer:
in one revolution the car travels:
