What is the difference between cross-section and intersection in geometry?
Triss [41]
A cross-section is the shape that would be exposed when cutting straight through a 3-D object. for example, cutting horizontally through a regular cone would expose a circle.

an intersection is where 2 or more shapes (does not matter how many dimensions) overlap. for example, the point at which two lines overlap is the intersection. or the area that two overlapping circles share is the intersection.

The function c=1.50(n-2)+5.50
qwelly [4]

Answer:

c =1.50n +2.50

Step-by-step explanation:

c=1.50(n-2)+5.50

The first step is to distribute the 1.5

c= 1.50*n -1.50*2 + 5.50

c = 1.50n - 3.0 +5.50

Now we need to combine like terms

c =1.50n +2.50

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
