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°
If you assume the sequence is geometric, then the common ratio will be
Then the boxes left-to-right are
.. 8p, -(5 1/3)p, ..., -(2 10/27)p
I don't know how you've been taught to describe the pattern, but it amounts to
.. A → (-2/3)×A
Answer: 49
Step-by-step explanation:
There would be 49 dots because each number is a square number. You skip 1 so every square‘s number is one less than the square root of the number of dots.
hope this helps
