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:
No please! Mr excuse me I am not your type bye
Answer:
y</= 2
Step-by-step explanation:
9 + 1 = 10
9 + 2 < 10
y = anything < 2
Answer: C
Step-by-step explanation:
The equation is 3x = 6, that represents 3 x ? = 6, babe. 3 x 2 = 6, so that means C must be the answer. If it was D, it would be 0.2 I think, and if it was B, it would’ve been -2. If it was A, it would’ve been 0. Bye-bye toots~
hope I'm right but either 2 or 4 i can kinda go either way
