Try dividing 600 by 5..
600 / 5 = 120
then times 120 by 9 to get the whole number = 1080
Answer:
x = 0, π/4, π, 7π/4
Step-by-step explanation:
sin(2x) = √2 sin x
Use double angle formula.
2 sin x cos x = √2 sin x
Move everything to one side.
2 sin x cos x − √2 sin x = 0
Factor.
sin x (2 cos x − √2) = 0
Solve.
sin x = 0, cos x = ½√2
x = 0, π/4, π, 7π/4
The answer is 1 cm = 1.6m. We know this because the scale model was 25 cm and the building was 40m. To simplify, our proportion is 40 meters /25 centimeters to x meters/1 centimeter. 40/25= 1.6, so we can say that x (the scale factor) is 1 cm to 1.6 m.
