Answer:
$147.46
Step-by-step explanation:
CP= x
SP= x+ 50%= 1.5x
1.5x- 4%= 230.40
1.5x*0.96= 230.4
x= 230.4/1.5*0.96
x= 147.456 ≈ $147.46
Let the length be l.
Formula of perimeter is P= 2(length +width )
1313 =2 (l+w)
l = \frac{1313}{2}-w
And the formula of area of rectangle = length times width .
A = l*w
A= (\frac{1313}{2}-w )*w
A = \frac{1313w}{2} -w^2
And that's the required objective function .
The equation represents parabola and a parabola is maximum at its vertex .
And the formula of vertex is
w = -\frac{b}{2a} =-\frac{1313}{4}
Substituting this value of w in the formula of area, we will get
A= \frac{1313*1313}{8} -(\frac{1313}{4})^2
Area= \frac{1723969}{16}=107748 \ square \ units .
Answer:
(2,7)
Step-by-step explanation:
We know that the change in x from A to M is -2, and the change in y is 1 -- we can simply double that and add that to A to get B, as M is halfway between A and B. Thus, (6,5)+(-4,2)=(2,7) as the coordinates of B
