Okay, so first you draw a picture and let x be the distance from point D to the rest stop. Then the distance from point to the rest stop is 8 - x
You know that the length of the new trail is y + z, where y is the distance from Ancaster to the rest stop and z is the distance from Dundas to the rest stop.
Now by the Pythagorean theorem, y^2 = 4^2 + x^2 and z^2 = 6^2 + (8 - x) ^2
So take square roots of these, add them, and minimize.
Note: I am assuming the path is perfectly straight, otherwise this approach fails.
Answer:
x+6
Step-by-step explanation:
first you open up brackets by BODMAS rule.. then its simple subtraction
A. discriminant = 52;
B. 2, because 52 > 0
C. - discrminant / 4a = -52 / -12 = 6 > 0 => <span> the vertex of the graph of the equation lie above the x-axis.</span>
"It shifts the graph down 4 units" is the effect that the number 4 have on the graph, in the function y=-2(x-1)^2+4 when <span>compared to the graph of the function y=x^2. The correct option among all the options that are given in the question is the third option or option "C". I hope the answer has come to your help.</span>
