There are 2 short sides x and 1 long side y.
x+x+y=1,800
2x+y=1,800
y=1,800-2x
The area of the rectangle is A=x(1,800-x).
A is a function with variable x. Moreover it is a quadratic (second degree) function.
The graph of the function is a parabola which opens downwards, because the signs of the leading coefficients of the factors, multiply to minus:
(x)(-x)=-x^2.
This means that the highest point of the parabola, is its vertex V(h,k), so the function takes its largest value for x=h.
The roots of A=x(1,800-x) are x=0 and x=1,800, thus the x coordinate of the vertex, must be the midpoint of 0 and 1,800, that is 900.
Answer:
A=x(1,800-x)
largest area is when x=900
Answer:
The answer is x = -13/4
Step-by-step explanation:
-13/4 + 2 / -13/4 +3 = 5

The longest spin of a basketball on one finger is 255 minutes or 4.25 hours.
Step-by-step explanation:
the longest spin of a basketball on one finger is 255 minutes.
We need to find how many hours is that.
So, we need to convert 255 minutes into hours.
We know that,
60 minutes = 1 hour
Using Unitary method:
60 minutes = 1 hour
1 minute = 1/60 hour
255 minutes = 1/60 * 255 hour
255 minutes = 255/60 hour = 4.25 hour
255 minutes is 4.25 hour.
So, The longest spin of a basketball on one finger is 255 minutes or 4.25 hours.
