Since it is a square, all sides are equal.
Divide the 440 by 4 to find the length of each side.
440/4 = 110 yards
Distance = √(x2-x1)² + (y2-y1)²
= √(2+1)² + (8-9)²
= √3² + (-1²)
= √ 3+1
= √4
= 2
In short, Your Answer would be 2 units
Hope this helps!
Answer is 20 by plugging the 4 in the equation it equals 20
The first step is to find the distance from the given point to each of the two foci as follows:
Distance D1:
(D1)^2 = (9-1)^2 + (0-6)^2 = 100
D1 = 10
Distance D2:
(D2)^2 = (11-1)^2 + (6-6)^2 = 100
D2 = 10
The constant sum is the summation of the two distances as follows:
constant sum = D1 + D2 = 10 + 10 = 20
The correct choice is:
a) 20
THis will be the coordinates of the point at a turning point on the graph.
Since the second derivative is positive (=1) it will be a minimum value of f(x).
