Answer:
minutes
Step-by-step explanation:
<u>Given information:</u>
- Track is 400m long
- Mai runs at a constant speed of 250 meters/minute
- - - - - -
To find how many minutes it takes for Mai to complete 4 laps, we need to find the total distance Mai is running for:
meters
To find how many minutes Mai is running for, we divide by the distance Mai travels per minute:
minutes
∴ Mai takes
minutes to run 4 laps around the track.
Hope this helps :)

Step-by-step explanation:
Since the sine function and cosine function is negative hence, the angle theta must lie in 3rd quadrant.
In 3rd quadrant, tangent and cot functions are positive.
a)

b)

Answer:
Options 2), 4 , and 5 are CORRECT
Step-by-step explanation:
Notice that z * 3 1/3 = z * (3 + 1/3) = z * (9/3 + 1/3) = z * 10/3 = 10/3 z
1) The first option is not good'
2) 6 z - 2/3 z - 3 z + z = 4 z - 2/3 z = 12/3 z - 2/3 z = 10/3 z So this option is CORRECT
3) z * 4 - 2/3 is not good since 2/3 is not multiplied by z
4) z ( 4 - 2/3) = z (12/3 - 2/3) = z * 10/3 so this one is CORRECT
5) z (1 / 3 + 3) = z ( 1/3 + 9/3 ) = z (10/3) So this one is also CORRECT
