Using Pathogorean Theorem.....
40 = the square root of 24^2 + 32^2
40 = the square root of 576 + 1024
40 = the square root of 1600
40 = 40
Answer:
B) 1/2
Step-by-step explanation:
If Ethan rolls a 6 sided number cube, the probability that he gets a number less than 4 is 1/2.
Less than 4: 3,2, or 1.
3 is half of 6.
Therefore it is 1/2 or 50%
The first one since the 5 has the radical symbol
Answer:
22.8 m/s at 17.4°
Step-by-step explanation:
You want to find the resultant of ...
3 cis 0° +20 cis 20° = (3, 0) +(18.794, 6.840) = (21.794, 6.840)
The magnitude is the root of the sum of the squares of the velocities in the horizontal and vertical directions:
s = √(21.794² +6.840²) ≈ 22.8
The direction is found from the fact that the tangent of the angle is the ratio of vertical to horizontal coordinates:
angle = arctan(6.840/21.794) ≈ 17.4°
The resultant velocity is 22.8∠17.4° meters per second.
Assuming the typewriter-looking words are the line names...
1. Line R
2. Line Q (Or R, but it is most likely Q)
3. Points E and F
