Compare the functions shown below:
emmasim [6.3K]
The intersection with the y axis occurs when x = 0.
 We have then:
 
 For f (x):
 
f (0) = -3 (0) - 5

f (0) = 0 - 5

f (0) = - 5

 For g (x):
 
We can observe in the graph that when x = 0, the value of the function cuts to the y axis in y = -3

 For h (x):
 
h (0) = 2cos (2 (0) -\pi) +4

h (0) = 2cos (0-\pi) +4

h (0) = 2cos (-\pi) +4
 h (0) = 2 (-1) +4

h (0) = -2 + 4

h (0) = 2

 Therefore, the graph with the intersection with the largest y axis is h (x)

 Answer:
 
the greatest y-intercept is for:
 
C. h(x)

The angle of depression from the basketball hoop to Clairs eyes is 9.2degrees. The vertical distance from the ground to Claires
Norma-Jean [14]
X - difference between the height of the basketball hoop and the vertical distance from the ground to Clair´s eyes.
Using T O A:
tan (9.2°) = x / 22 ft
x = tan (9.2°) · 22 ft
x = 0.162 · 22 ft 
x = 3.564 ft
The height of the basketball hoop is:
h = 5.6 + 3.564 = 9.164 feet
