Answer:
The change in the angle of elevation is approximately 63.435°
Step-by-step explanation:
The given parameters are;
The speed of the tightrope walker = 3 ft./sec
The altitude at which the tightrope walker is moving = 100 ft.
The horizontal distance of the tightrope walker from the searchlight = 200 feet
The final angle of elevation, θ, is given by the trigonometric ratio as follows;
Whereby the tightrope walker was initially vertically overhead the search light, the initial angle of elevation = 90°
The change in the angle of elevation = The initial angle of elevation - The final angle of elevation
Substituting the values gives
The change in the angle of elevation = 90° - 26.565 ≈ 63.435°

This is an absolute value , for example |-6| = 6 and |-0| = 0 so your answer is
Y >= 0 ( your last choice)
Answer:
x = 3
x = 0
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:
2x^2 - 6x = 0
Pull out like factors
2x * (x - 3) = 0
Solve: 2x = 0
Divide both sides of the equation by 2:
x = 0
Solve: x-3 = 0
Add 3 to both sides of the equation:
x = 3
