Look here, what do you see?
I have five problems attached. I wasn't sure about my answers.
6. I couldn't solve.
7. 14.3
8. 40.4
9. 39.2
10. y(squared) = 2(x-15)squared + 775
The shortest distance is 28.
The last part of problem 10 is Draw an accurate picture of this path, and make a conjecture about angles AED and BEC. Use your protractor to test your conjecture.
1. This method is only valid if the distance is calculated by a single square-root.
2.
3. Differentiate d wrt x. You'll get:
Now solve for x: d'(x) = 0
Caution: To solve this equation you need a lot of paper and even more patience. Finally you should come out with x = 18.
4. Thus the minimum distance is:
