X^2-10x+25, not exactly sure if thats what u meant but hope it still helps
Answer:
Ricky it is 1,202
And for Pedro = 1,202 + 276 = 1,478
Step-by-step explanation:
The computation is shown below:
Let us assume the ricky be x
So pedro be x + 276
Now the equation is
x + x + 276 = 2680
2x + 276 = 2680
2x = 2680 - 276
2x = 2404
x = 1,202
For Ricky it is 1,202
And for Pedro = 1,202 + 276 = 1,478
Answer:
-2/6
Step-by-step explanation:
go down the y axis 2 times (-2) and over 6
y=-2/6x+4
why did you white the next part out, im sure it held some information. anyways, judging from the picture the segment bisector is line QS, so draw a line (segment with arrows sticking out of its two sides) above the two letters QS.
Answer:
A) Dimensions;
Length = 20 m and width = 10 m
B) A_max = 200 m²
Step-by-step explanation:
Let x and y represent width and length respectively.
He has 40 metres to use and he wants to enclose 3 sides.
Thus;
2x + y = 40 - - - - (eq 1)
Area of a rectangle = length x width
Thus;
A = xy - - - (eq 2)
From equation 1;
Y = 40 - 2x
Plugging this for y in eq 2;
A = x(40 - 2x)
A = 40x - 2x²
The parabola opens downwards and so the x-value of the maximum point is;
x = -b/2a
Thus;
x = -40/2(-2)
x = 10 m
Put 10 for x in eq 1 to get;
2(10) + y = 40
20 + y = 40
y = 40 - 20
y = 20m
Thus, maximum area is;
A_max = 10 × 20
A_max = 200 m²
