The complete question in the attached figure
we know that
If two chords intersect in the interior of a circle, then
the product of the lengths of the segments of one chord
is equal to the product of the lengths of the segments of
the other chord
(Segments of Chords Theorem)
therefore
AB*BC=DB*BE
AB=x
BC=x
DB=62
BE=250-62---------> BE=188 ft
so
x*x=62*188----------> x²=11656--------> x=√11656--------> x=107.96 ft
the answer is x=107.96 ft
At start: PE only
At end: KE and energy lost to friction
PE = KE + E
E = PE - KE
= mgh - (1/2)mv^2
= (40)(9.8)(12) - (.5)(40)(10)^2
= 2704J
Answer:
There is something called "criteria of congruence for triangles".
Those criteria say that, with some data of the triangles, we can know if the triangles are equivalent.
For example one of the criteria is SSS.
Side-side-side.
This means that all the triangles with equal side length for all their sides are equivalent.
So if the information that we give to the factory is the side length of the 3 sides of the triangle, the triangle will be well defined.
Following those criteria, the other 2 options can be:
SAS
Side-Angle-Side
(so you can give the length of two sides and the angle between them)
ASA
Angle-Side-Angle.
(You can give the value of two angles and the length of the side between those two angles)
Divide 237.50 by 25. The answer is $9.50 per hour
