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
The statement "The whole number has one digit if and only if the whole number is less than 10" is true for converse statement. Then the correct option is C.
<h3>What are converse statements?</h3>
A inverse statement is one that is derived by opposing the supposition and result of a relative clause.
Let p: The whole number has one digit.
Let q: The whole number is less than 10.
The statement "The whole number has one digit if and only if the whole number is less than 10" is true for converse statement.
If p → q, then, q → p
Then the correct option is C.

principal (p)=62500,Time (T)=1.5 years,Rate (R)=8% Ammount=p (1+R÷100) =62500 × 1.1664 =72900 again, compound interest = p(1+R÷100)-1=62500×0.1664 = 10400
Uh i think it’s uhh.... i think it’s a carrot
