Respuesta :
The area of delivery of Zippy's Pizza given by a radius of delivery is a
circular area.
- First Question: x² + y² = 4²
- Second Question: √5 miles to the west and √5 to the east from route 26
- Third Question; The distance between Little Cub's Field and Zippy is 2·√5 miles
- Fourth Question: The distance between Little Cubs Field and the radius of delivery is 2·(2 - √5) miles.
Reasons:
Direction of Empire Street = East to west
Direction of route 26 = North to south
Location of Zippy's Pizza parlor on route 26 = 3 miles south of Empire street
The radius of the area Zippy makes delivery = 4 miles
Question One:
Required: Equation for the radius of delivery
Solution:
The equation of a circle is (x - h)² + (y - k)² = r²
Where;
(h, k) = The coordinates of the center of the circle
r = The radius of the circle
Where the center of the circle is at the origin, we have;
(h, k) = (0, 0)
Therefore, the equation that represents the radius of delivery for Zippy's Pizza is is; (x - 0)² + (y - 0)² = r²
x² + y² = r²
The radius r = 4, the equation is therefore;
- x² + y² = 4²
Second Question;
The equation that represents Empire street with Zippy's Pizza at the origin is y = 3
Therefore at the maximum distance east and west, along Empire street, we have;
x² + 3² = 4²
x² = 4² - 3² = 5
x = ±√5
The distance east and west along Empire street where one can still receive pizza are; √5 miles west and √5 east from Route 26
The maximum distances from route 26 a person can live on Empire street and receive pizza are;
- √5 miles to the west and √5 to the east from route 26
Question Three;
The location of Little Cubs Field = 2 miles west and 4 miles north from Zippy's
The coordinates of Little Cubs Field relative to Zippy at the origin is therefore;
Little Cubs Field coordinates = (-2, 4)
The distance between Little Cub's Field and Zippy, d = √((-2)² + 4²) = 2·√5 miles
Question Four;
The distance between Little Cubs Field and the radius of delivery is given as follows;
D = d - r = 4 - 2·√5
The distance between Little Cubs Field and the radius of delivery is D = 2·(2 - √5) miles.
