Ben is climbing a tree with a lot of branches. His height off the ground at time t is 2t^2-5t+29 feet. To the nearest foot, what will his minimum height be?
We use the formula x=-b/2a to find the minimum.
This is the x value though, so we plug it into the equation(t is the x value) y= 2t^2-5t+29.
I am not entirely sure if this is right, so please tell me.
The minumum TIME will be - b/ 2a = - -5/4 = 5/4 Yes you got that part right
Now sub t = 5/4 into the equation to find the minimum HEIGHT
Heightmin= 25 7/8 ft Ye, you got that part correct too ! (or ...at least we got the same answer! )
