Enter the expression 2cos2(θ)−1 , where θ is the lowercase Greek letter theta. 2cos2(θ)−1 2 c o s 2 ( θ ) − 1 = nothing
yulyashka [42]

We have to evaluate

=2 cos 2Ф - 1

⇒cos 2Ф

A =2cos²Ф-1

 B =1 -2 sin²Ф

 C = cos²Ф - sin²Ф

Possible Answers are

1.

=2 ×(2cos²Ф-1)-1

=4cos²Ф-2-1

=4cos²Ф - 3

2.

=2×(1 -2 sin²Ф)-1

=2- 4sin²Ф-1

=1 - 4sin²Ф

3.

=2× ( cos²Ф - sin²Ф) -1

=2 cos²Ф - 2sin²Ф-1

Nyoko needs to be at school at 7:45 AM. It takes her 15 minutes to walk to school, 5/12 hour to eat breakfast, 0.7 hour to get d
defon
So, she wants to be at school at 7.40 (5 mins early)

she needs:

15 mins
5/12 hours (which is \frac{5}{12} = \frac{25}{60}, so 25 mins

so far: 40 mins

then 0.7 and 0.15: we can add those, since they're in decimals: 0.85.

how many minutes is this?

\frac{85}{100} *60=  \frac{85}{10} *6=\frac{85}{5} *3=\frac{13}{1} *3=39

so 39 mins.

together with the previous 40, it's 79 minutes, which is 1 hour and 19 minutes: so she needs to wake up 1 hour and 19 minutes before 7.40 , which is
