Hello, there!

»ANSWER«

What is the amplitude, period, and phase shift of f(x) = −4 sin(2x + π) − 5?

Amplitude = −4; period = 2π; phase shift: x = negative pi over two

Amplitude = −4; period = π; phase shift: x = pi over two

Amplitude = 4; period = π; phase shift: x = negative pi over two

Amplitude = 4; period = 2π; phase shift: x = pi over two

Amplatitude: - 4

K = 2; Period:

Phase shift: pi

entering that problem on the tube might get you an answer

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
