Step-by-step explanation:
As the attachment shows, for the given directrix and eccentricity, the equation is ...

You find a common denominator (the bottom one) and then add the numerator (the top) but you don't add the denominator, you just make it the same
Answer:
7
or -7
Step-by-step explanation:
sqrt(49)
What number multiplied by itself = 49
7*7 = 49
-7*-7 = 49
Answer:
The length of slide is 18.36 meters
Step-by-step explanation:
The given scenario forms a right-angled triangle where
The height of tower id perpendicular, the distance between slash pool and base of tower is base and the length of slide will be hypotenuse.
Height of tower = h = 16 meters
Distance between slash pool and base of tower = b = 9 meters
Length of slide = s = ?
As it is a right angled triangle, we can use Pythagoras theorem to find the length of slide
Pythagoras theorem states that:

Hence,
The length of slide is 18.36 meters
