Step-by-step explanation:
Given a quadratic equation which is a polynomial equation in terms of a variable x of the form ax^2+bx+c=0. The quadratic formula for solving a quadratic equation is:
x=[-b+/-√(b²-4ac)]/2a
where a,b and c are the respective coefficients as indicated in the quadratic form.
The actual distance between Yappy city and Quiet city when it is 23 cm in map is 9.2 miles.
What is scaling ?
It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.
It is given that :
The distance on the map between Yappy city and Quiet city is 23 cm
and,
5cm = 2 miles
now, for 1 cm on map it is equal to 2/5 miles of actual distance.
Therefore to find the actual distance of 23 cm in map we simply multiply 23 with 2/5 :
actual distance :
2/5 x 23 = 9.2 miles
Therefore, the actual distance between Yappy city and Quiet city is 9.2 miles.
