Answer:
396
Step-by-step explanation:
Answer:
Because θ lies in quadrant II, 2θ must lie in quadrant IV. This means the tangent of 2θ is negative.
The adjacent side to θ is 7 because √(25²-24²)=7, so tanθ=7/24.
The double angle formula for tangent is tan 2θ = (2 tan θ) / (1 − tan² θ).
Substituting the value for tanθ in and keeping in mind that this is in quadrant IV, we get tan 2θ = -(2(7/24)/(1-(7/24)²)).
Simplified, this becomes tan 2θ = -336/527.
Therefore, the answer is C. -336/527.
Solution:
<u>Note that:</u>
- Given sentence: The difference between an integer p and (-5) is 1.
<u>Let's reread the sentence carefully.</u>
The difference between an integer p and (-5) is 1.
<u>Change the sign.</u>
<u>Subtract 5 both sides:</u>
- p + 5 = 1
- => p + 5 - 5 = 1 - 5
- => p = -4
