Hi all.
I've done pre much everything but part b.ii.
Any help appreciated.
Ty in advance.
Hi! I don't have time to solve the entire question, but I can give you some pointers on where to start.
Firstly, find the coordinates of that top corner of the truck, you know the height and width, and that the truck drives directly through the arcs middle. Therefore, that top right corner will be (1/2*2.7, 3.7).
You also know that any point along the parabola will have the coordinates (x, x^2+whatever number you found in the previous part).
Then, you need to substitute these coordinates into the distance formula, which will give you some distance function with x in it. Since it asks for minimum distance, you can diff the function, let it equal 0 and solve for the x value (use CAS). Finally, put this x value in back in the distance formula to get back a distance.
I hope this helps a bit! Let me know if you need me to clarify anything.
