The answer is 265 .Use the formula that Sn.
Answer:
the new equation is f(x)=x^2-4
vertex- (0,-4)
zeros- (-2,2)
y-intercept- (-4)
and it has a minimum
Step-by-step explanation:
Let width of the rectangular plot be x meters
then total of widths = 2x
and the length would be (550 - 2x) meters.
so the area = x(550 - 2x) = 550x - 2x^2
to find the maximum are find the derivative and equate to zero:-
f'(x) = 550 - 4x = 0
x = 550/4 = 137.5 meters = width
length = 550 - 2(137.5) = 275
Maximum area is when width = 137.5m and length = 275m
Aww thank you. Im pretty sure you helped people cause you helped me :) I hope you have an amazing day!
