Answer:
m=-9+n
Step-by-step explanation:
you want to get m by itself so you subtract 9 on both sides. 9-9 crosses out and you get m by itself. Which leads you to m= -9+n
Answer:
The scale of the map is inch = 20 feet.
This statement must be incorrect or the fraction of the inch is missing.
Because 6" long, at a scale of one inch = 20 feet, would only be 120 feet x 120 feet.
120 x 120 = 14,000 ft^2 and each of the four quadrants wouls only be 3600 ft^2.
Increase = 14
Total =50
Percentage increase = 14/50 x 100 = 28%
Answer:
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Begin with the right hand side:
R.H.S = cot θ =
L.H.S = sin θ cos θ
so, sin θ cos θ ≠ 
So, the equation is not a trigonometric identity.

<u>Anther solution:</u>
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Assume θ with a value and substitute with it.
Let θ = 45°
So, L.H.S = sin θ cos θ = sin 45° cos 45° = (1/√2) * (1/√2) = 1/2
R.H.S = cot θ = cot 45 = 1
So, L.H.S ≠ R.H.S
So, sin θ cos θ = cot θ is not a trigonometric identity.
