Answer:
- 160 ft (out from the river)
- 320 ft (parallel to the river)
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the dimension of perpendicular to the river will be half the remaining fence: (640-x)/2. The total area will be ...
A = x(640-x)/2
This is the equation of a parabola that opens downward. It has zeros at x=0 and x=640, so its axis of symmetry is x = (0+640)/2 = 320. That is, the peak of the area curve is found when x=320.
The dimensions of the garden with the largest area are 160 ft wide by 320 ft long, where the long side is the river side.

Answer:
<u>add up all numbers</u>
<u>then divide that number by the amount of numbers.</u>
Step-by-step explanation:
mad is basically finding the average of a set of numbers.
and how do you do that?
first, add up all numbers
ex: 1, 5,3,10,6,20,15,15,14 --> this adds up to 90.
then divide that number by the amount of numbers.
count how much numbers ehere are: there are 9 numbers.
divide 90 by 9 and the mad/average is 10.

Answer:
y = 3x + 9
Step-by-step explanation:
y = 3x + 6
Parallel slope = 3
(-2, 3)
Slope-intercept:
y - y1 = m(x - x1)
y - 3 = 3(x + 2)
y - 3 = 3x + 6
y = 3x + 9
