We are given with two points of a parabola : v (5,-1) and f (3,-1). In this case, we can see that the parabola is opening to the left which means the standard form to be followed is -4a(x-h) = (y-k)^2. a is equal to 2. substituting, -4*2 (x-5) =(y+1)^2. This is equal to -8 (x-5) = (y+1)^2
Answer: 6 inches
Step-by-step explanation:
From the question, we are informed that a map in Connecticut is drawn to a scale where 2 inches on the map represents 35 miles.
If Greenwich and stonington are 105 miles from each other, to calculate their distance on the map will be:
Since 2 inches represent 35 miles, then: 1 inch = 35miles/2 = 17.5 inches.
Since 1 inch = 17.5 inches;
105 inches will then be: 105inches/17.5 inches = 6 inches
Therefore, 6 inches represent 105 miles.
