Side of the playground would be : a²+a² = 16²
2a² = 256
a² = 128
a = √128
a = 11.31 m
Answer:
Step-by-step explanation:
Alright let's get started.
Please refer the diagram I have attached.
we have given a square playground whose diagonal is 16m.
Let us assume the side of the square is a.
Now, by applying the Pythagorean theorem we can find the side of the square which is:
Hence, the side of the playground is 11.3m. : Answer

Answer:
The lens is 1 inch from the mirror
Step-by-step explanation:
* Lets revise the equation of the hyperbola with center (0 , 0) and
transverse axis parallel to the y-axis is y²/a² - x²/b² = 1
- The coordinates of the vertices are (0 , ± a)
- The coordinates of the co-vertices are (± b , 0)
- The coordinates of the foci are (0 , ± c) where c² = a² + b²
* Lets solve the problem
∵ The equation of the hyperbola is y²/16 - x²/9 = 1
∵ The form of the equation is y²/a² - x²/b² = 1
∴ a² = 16
∴ a = √16 = 4
∵ The coordinates of the vertices are (0 , ± a)
∴ The coordinates of the vertices are (0 , 4) , (0 , -4)
∴ b² = 9
∴ b = √9 = 3
∵ c² = a² + b²
∴ c² = 16 + 9 = 25
∴ c = √25 = 5
∵ The coordinates of the foci are (0 , ± c)
∴ The coordinates of the foci are (0 , 5) , (0 , -5)
∵ The camera is pointed towards the vertex of the hyperbolic mirror
which is (0 , 4) and is positioned such that the lens is at the nearest
focus to that vertex which is (0 , 5)
∴ The distance between the lens and the mirror equal the distance
between the vertex and the focus
∵ The vertex is (0 , 4) and the nearest focus is (0 , 5)
∴ The distance = 5 - 4 = 1 inch
* The lens is 1 inch from the mirror
