<span>h = 0 when it hits the ground, therefore:
-16t^2 + 48t = 0
--------------------------------------...
Factor out -16t
-16t(t + 3) = 0
:
Two solutions
t = 0, when it begins it's upward journey
and
t = 3 sec, when it returns to earth

We know that
When two chords intersect each other inside a circle, the products of their segments are equal (Intersecting Chord Theorem)
so
8*18=x*6--------> x=8*18/6-----> x=24
the answer is
24
Answer:
Step-by-step explanation:
A = 8 cm
B = 5 cm
C = 22 - 8 - 5 = 9 cm
Use the Pythagreom Theroem (a^2 + b^2 = c^2) if the two sides are equal to one another than it is a right triangle.
8^2 + 5^2 = 9^2
64 + 25 = 81
89 = 81
89 does not equal 81, so this is not a right triangle.
