I am pretty sure it is a close circle for a. B is no. A child who is 46 inches tall can not ride the dollar coaster since they are 2 inches under the minimum height
74,000 is your answer
Hope this helps
1) you can expand the brackets, simplify, set the equation = 0 and then do a double bracket factorisation.
2)
therefore Josh's solution is wrong asx = 7 and x= -1
Answer:
15 meters
Step-by-step explanation:
The diagram of the problem is attached below in the first image.
Chords KM and LN (which is the diameter) intersect at X.
Theorem: If the diameter is perpendicular to a chord, it bisects the chord.
Therefore:
LN divides KM into equal parts of 6 meters,
Applying the theorem of intersecting chords:
KX*XM = LX*XN
6*6=3*XN
3*XN=36
XN=12
Next, we find the length of the diameter LN
LN=LX+XN
=3+12
=15 meters
The diameter of the completed circle is 15 meters.
