The answer is vertex is (5/2, 27/2).
Find x= -b/2a where a=-2, b=10 then plug x value back into function to solve for y value of vertex (x,y).
Answer:
A ≈ 28.27
Step-by-step explanation:
Answer:I’m sorry this is hard I don’t think I have the right answer chose C
Step-by-step explanation:
Remember that the area of a rectangle is the length of the rectangle multiplied by the width of the rectangle.
In this case, we could say (where 
is the area of the rectangle):
Substituting the values the problem gave us for 
and 
, we can find the formula for 
in terms of 
, which is:
The formula for the area of the rectangle would be A(x) = 10x³ - 20x² + 65x.
Answer:
