Join the centre O to the chord (let it be MN) & let OH be the perpendicular to the chord
OH bisects MN into 2 equal parts (each one is x/2)
OMH is a right triangle with one side =8, the second leg =x/2 & the hypotenuse = 12 (Radius)
Apply Pythagoras:
12² = 8² +(x/2)² ==>144=64 + x²/4 ==> x²=4(144-64) =320
x²=320==> x=√320 =17.88 ≈17.9
Answer:
$1008
Step-by-step explanation:
slope is 60/5.
(60/5)×84=1008
816/850x100 = 96
Therefore 96 % of tickets were sold.
117
Step-by-step explanation:
(x+3) is 13 because x is 10 so 10+3 is 13 and then 9 so 13×9 is 117
Answer:
=100000
Step-by-step explanation:
(10^2)(10^3)
=10^2*10^3
=(10*10)*(10*10*10)
=10*10*10*10*10
=105
=100000
