A parallelogram is not always a rectangle
Answer:
It depends on the situation being modeled.
Step-by-step explanation:
Assuming the vertex (8.33,236.67) is on a quadratic curve modeling height of an object in feet after t seconds.
Then t=8.33s is the time the object reached the maximum height.
The maximum height is the y-value of the vertex, which is 236.67 feet.
In this case the quadratic curve opens downwards.
The vertex is then the maximum point on this curve.
Answer:
LK=12
Step-by-step explanation:
From the given figure, HI=7 and LH=9, and we know that


(1)
Now, from ΔKHL, we have

and from ΔOKH,





(2)
Also, ΔIKL is similar to ΔOHL, therefore





Using equation (2), we get




Thus, the value of LK is 12.
