Frank -----------------------------------------------Base
Frank - Base = 400 ft
Base- Top statue = 360 feet
Angle of elevation =Angle Top-Franck-Base, let it be angle Ф
tan (Ф) = 360/400 = 0.9
arc tan (0.9) = tan⁻¹(0.9) = 41.98 ,
Ten angle of elevation Ф ≈ 42°
Answer:
91.2 mg of coffee left in your system 2 hours from consumption
Step-by-step explanation:
120 x .12 = 14.4
14.4 x 2 = 28.8
120 - 28.8 = ...
91.2 mg
Yup! Consider the circle:
r=cnt, for any angle. Impossible with (x,y), because for a given x, you need to y values. For a circle of radius 1, centered at the origin, y = +sqrt( 1-x^2) and y = -sqrt(1-x^2)
Also the spiral, etc ... Any hta has for one x value, two or more y values.
