Answer:
76,050 ft²
Step-by-step explanation:
If the area must be rectangular, let L be the length of the side opposite to the creek, and S be the length of the remaining two sides.
The perimeter of the fencing and the area of the pasture are:
The value of S for which the derivate of the area function is zero is the length of S that maximizes the area of pasture:
The maximum possible area is:
In both cases, we have cooling. We can add together the 2 functions describing this cooling: z(x) = 0.5x - 9 - [-x-2] = 0.5x - 9 + x + 2, or
z(x) = 1.5x - 7
Provided that this is correct, all we have to do now is to subst. 5 for x:
z(5) = 1.5(5) - 7 = 7.5 - 7 = 0.5 (answer)
Answer:
This equation would be y - 2 = 2(x - 5)
Step-by-step explanation:
In order to find this, we first need to find the slope.
m(slope) = (y1 - y2)/(x1 - x2)
m = (2 - -10)/(5 - -1)
m = 12/6
m = 2
Now that we have this, we can use this and the point (5, 2) to write the point-slope form.
y - y1 = m(x - x1)
y - 2 = 2(x - 5)
