Answer:
Step-by-step explanation:
we know that
If the terminal ray of β lies in the fourth quadrant
then
sin (β) is negative and cos (β) is positive
Remember the trigonometric identity
we have
substitute
apply root square both sides
Answer:
50.2
Step-by-step explanation:
202/4=50.2
Substituting the distance of 20ft (converted to approximately 6.096 meters) into the equation V^2=64s, we calculate that the pencil would hit the ground with a speed of approximately 31.4 m/s.
In this physics problem, we utilize the formula V^2=64s, which connects the speed (V) and the distance traveled (s). The step we are interested in involves substituting known values into our equation. Given that s
is an altitude of 20ft (which we convert to approximately 6.096 meters for consistency in units), we substitute this into our equation and solve for V. This yields V = √(64*6.096). By carrying out this square root, we determine that the pencil hits the ground at approximately 31.4 m/s.

The probability that Jonathan will arrive first and Michael will arrive second in their bikes to school is P ( A ) = 1/12
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability that Jonathan will arrive first and Michael will arrive second in their bikes to school is P ( A )
Now , the number of people = 4
So , the probability of each person to reach the school first = ( 1/4 )
And , the probability that the second person to reach second = ( 1/3 )
So , probability that Jonathan will arrive first and Michael will arrive second in their bikes to school is P ( A ) = ( 1/4 ) ( 1/3 )
P ( A ) = 1/12
Hence , the probability is P ( A ) = 1/12

Answer:
1/12
Step-by-step explanation:
Jonathan has 1/4 chance and so if Jonathan is already there, there are only 3 people left. 1/4*1/3 is 1/12.
