Answer:
The fundamental properties of rectangles are:
- A rectangle is a quadrilateral
- The opposite sides are parallel and equal to each other
- Each interior angle is equal to 90 degrees
- The sum of all the interior angles is equal to 360 degrees
- The diagonals bisect each other
- Both the diagonals have the same length
- A rectangle with side lengths a and b has the perimeter as 2a+2b units
- A rectangle with side lengths a and b has the area as: ab sin 90 = ab square units
- The sum of the interior angles is equal to 360 degrees
- A diagonal of a rectangle is a diameter of its circumcircle
- If a and b are the sides of a rectangle, then the length of each diagonal is:
- The diagonals bisect each other at different angles. One is acute, and another one is an obtuse angle
- If the two diagonals bisect each other at right angles, then the rectangle is known as a square
- A cylinder is obtained when the rectangle is rotated along the line joining the midpoint of the longer parallel sides. In this case, the height of the cylinder is equal to the width of a rectangle. Also, the cylinder diameter is equivalent to the length of a rectangle
- A cylinder is obtained when the rectangle is rotated along the line joining the midpoint of the shorter parallel sides. In this case, the height of the cylinder is equal to the length of a rectangle. Similarly, the cylinder diameter is equivalent to the width of a rectangle

Answer:
x = 1/20 y^2
Step-by-step explanation:
This is a rightward opening (sideways ) parabola
Directrix = x = -5
Distance formula form point x,y to directrix and focus are equal:
(x - -5)^2 = (x-5)^2 + y^2
x^2 + 10x + 25 = x^2 - 10x + 25 + y^2
20x = y^2
x = 1/20 y^2
Answer:
A 180-pound kangaroo's recommended height is 6 feet.
Step-by-step explanation:
Since 120-pound kangaroo is 5 feet tall and for every inch over this height we add 5 pounds to the total weight, we can make this formula. . Using this we can figure out the weight difference between a 120-pound kangaroo and a 180-pound kangaroo. After solving for x we get .
Now that we know the 180-pound kangaroo weighs 60 more pounds than a 120-pound kangaroo we can divide that weight difference by 5 to figure out the height difference.
After getting the height difference from the weight difference we can conclude that a 180-pound kangaroo's recommended height is 5 feet and 12 inches. Since 12 inches = 1 foot we can easily convert 5' 12" to 6'. This means that a 180-pound kangaroo is 6 feet tall.
