There are 39 left handed students at Toms school
Answer:
Step-by-step explanation:
- cotx cos x - cot x = 0
- cotx( cosx - 1) = 0
1. <u>cotx = 0</u>
- x = π/2 + πn
- In the interval [0, 2π] we have π/2 and 3π/2
2. <u>cosx = 1</u>
- x = 0 + 2πn
- In the given interval we have 0 and 2π
<u>So the solution set is:</u>
Answer:
C. Add the equations
Step-by-step explanation:
Adding both the equations will help eliminating 5y.
5. The answer is D

because it says no more than 160 so it's possible to be equal to 160.
6.

So the answer is A
Answer:
Unlikely
Step-by-step explanation:
