Yes it is because it’s parallel and it appear to be correct
Hello,
We suppose x≠+/-π/2.
2cos x - √2=0
==>cos x=√2/2
==>x= π/4 or x=3π/4 (modulo 2π)
He swam 1,800 laps total in 12 weeks. Each week, he swam 150 laps because 1800/2=150 in 5 days. Each day, he swam 30 laps because 150/5=30, in 45 minutes. His average time was 30/45=2/3 At that rate, in one hour, he would swim 2/3*60 = 2/3 x 60 = 40 laps/hour Final answer is 40
64/3.2 = 20
The answer is 20
