Answer:

A) 2/3

B) 4 sqrt 30/9 = y

C) P= 3/4 * sqrt 2

Step-by-step explanation:

A.) A = K*B

1= K * 3

K = 1/3

Now we will find the unknown A value

A = 1/3 * 2

A= 2/3

B) x=k* y^2

27 = k * 4^2

K= 27/16

Now , we will find the unknown value of y

10= 27/16 * y^2

10*16/27 = y^2

Sqrt of 160/27 =y

4 sqrt 10/3 sqrt 3 =y

4 sqrt 30/9 = y

C) p = k * sqrt Q

3= k * sqrt 16

3 = k * 4

K= 3/4

Now, when we substitute the value of k in to the variation

P= 3/4 * sqrt 2

A gardener has 640 feet of fencing to fence in a rectangular garden. One side of the garden is bordered by a river and so it doe

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.
