Chris wants to fence three sides of a rectangular exercise yard for his dog. The fourth side of the exercise yard will be a side
Semmy [17]

Answer:

  • parallel: 60 ft
  • perpendicular: 30 ft
  • area: 1800 ft^2

Step-by-step explanation:

Let x represent the length of fence parallel to the house. Then the length perpendicular is ...

  y = (120 -x)/2

The area of the yard is the product of these dimensions, so is ...

  A = xy = x(120-x)/2

This is the equation of a parabola that opens downward and has zeros at x=0 and x=120. The maximum (vertex) is on the line of symmetry, halfway between these zeros, at x=60.

The fence parallel to the house is 60 feet.

The fence perpendicular to the house is (120-60)/2 = 30 feet.

The area of the yard is (60 ft)(30 ft) = 1800 ft^2.

Why is 6/8 greater than 5/8 but less than 7/8
Olenka [21]
Because if you draw a three pies and cut all of them into 8 pieces and shade 6 in one, 5 in the other, and 7 into the last one, you will see that there is a bigger piece shaded in the one with 6 shaded than the pie with 5 shaded. And less shaded than the one with 7 shaded.

What are the coordinates of point P on the directed line
lutik1710 [3]

Answer:

<u>(</u><u>-3.5, 2.3</u><u>)</u>

Step-by-step explanation:

Let the point P have coordinates : (x, y)

The line (from R to Q) is divided in the ratio :

Coordinates of :

  • Q = (-5, 3)
  • R = (4, -1)

Using section formula :

  • x = mx₂ + nx₁ / m + n
  • x = 5(-5) + 1(4) / 5 + 1
  • x = -21/6 = -7/2
  • x = -3.5

  • y = my₂ + ny₁ / m + n
  • y = 5(3) + 1(-1) / 5 + 1
  • y = 14/6 = 7/3
  • y = 2.3

The coordinates of the point P are : <u>(</u><u>-3.5, 2.3</u><u>)</u>
