Step-by-step explanation:
Given that,
Directrix, d= -5, and eccentricity, e = 2.
The polar equation of the conic is given by :
Put all the values,
As e>1, it is a hyperbola. Hence, this is the required solution.
A) We know that
where d
= distance,
v = velocity,
t = time
In this case, d = 2 mi., t = 30 min. So we get
Dividing both sides by 30, we get
Thus a function for his walk would be
where y = distance and x = number of minutes he walks.
b) Domain of a function is a set of x-values on which the function defined. In this case, the number of minutes is 30 at maximum. So the domain of the function is [0, 30].
