Answer:

Step-by-step explanation:








OK. I used my calculator to evaluate sec(85 degrees).
My calculator doesn't have a "sec" button on it.
But I remembered that
sec of an angle = 1 / (cosine of the same angle) .
So I used my calculator to find cos(85), and then I hit the
" 1/x " key, and got 11.474, which I knew to be sec(85).
Answer:

Answer:
See answer below
Step-by-step explanation:
This is a separable equation, so we solve it like this:

Then
for any constant k (this is the general solution). This solution is defined in (-∞,∞) (there are no singularities) and when x tends to infinity, no terms of the solution vanish, hence there are no transient terms.
Answer:
.2
Step-by-step explanation:
The probability has to sum to 1
Red + yellow + green + black + white = 1
.25+ .30 + .05 + black + white = 1
.6 + black + white =1
subtract .6 from each side
.6-.6+ black + white = 1-.6
black + white = .4
They said black and white received the same number of votes, so they will have the same probability
2 black = .4
Divide by 2
2 black /2 =.4/2
black =.2
