PLEASE HELP ME.....
Virty [35]

Answer:

They would meet each other at 01 : 24 PM.

Step-by-step explanation:

  • Erik took a trip to see his friend Mike who lives 308 miles away.
  • He left his place at 10 AM driving at 70 mph.
  • In 2 hours, his friend Mike left his place driving towards Erik at an average speed of 50 mph.

As Erik left his house at 10 AM driving at 70 mph and in 2 hours, his friend Mike left his place driving towards Erik at an average speed of 50 mph. It means

Erik left his place at 12:00 PM noon.

so, at 12:00 PM Erik had already traveled:

                                                                      2\times 70=140\:\:miles

Miles left =308-140=168\:\:miles

Let 't' be the time when they meet

so

70t\:+\:50t\:=168

120t=168

\mathrm{Divide\:both\:sides\:by\:}120

\frac{120t}{120}=\frac{168}{120}

t=\frac{7}{5}

so

t=\frac{7}{5}=1.4\:\:hours

or 1 hour and 24 minutes after 12:00 noon

i.e.

12\:+\:1.4\:=1\:O'clock\:+\:24\:minutes

Therefore, they would meet each other at 01 : 24 PM.

Simplify (tan(θ)+cot(θ))/(sec(θ)•csc(θ)) completely
AlekseyPX
\dfrac{\tan\theta+\cot\theta}{\sec\theta\csc\theta}=\dfrac{\dfrac{\sin\theta}{\cos\theta}+\dfrac{\cos\theta}{\sin\theta}}{\dfrac1{\cos\theta}\dfrac1{\sin\theta}}=\dfrac{\sin^2\theta+\cos^2\theta}1=1
