Answer:
Therefore the angle of intersection is 
Step-by-step explanation:
Angle at the intersection point of two carve is the angle of the tangents at that point.
Given,

and 
To find the tangent of a carve , we have to differentiate the carve.

The tangent at (0,0,0) is [ since the intersection point is (0,0,0)]
[ putting t= 0]

Again,

The tangent at (0,0,0) is
[ putting t= 0]

If θ is angle between tangent, then






Therefore the angle of intersection is
.
The independent variable is x
y is dependent on the value of x
Answer:
it's part of the real number system
it's a rational number
it's an integer
Step-by-step explanation:
1 mi = 5280 ft
1 h = 3600 s
therefore:

Answer: 31.8 mi/h = 46.64 ft/s
