Answer:
(C)19
Step-by-step explanation:
The diagram is drawn and attached.
Using the intersecting chord theorem
SL X LT = JL X LK
x X 12 = 14(x-1)
12x=14x-14
12x-14x=-14
-2x=-14
x=7
Therefore:
ST= SL + LT
=x+12
=7+12
ST=19
The correct option is C
Answer:
336 Hours = 1,209,600 Seconds = 1209600 Seconds\
Step-by-step explanation:
This conversion of 336 hours to seconds has been calculated by multiplying 336 hours by 3,600 and the result is 1,209,600 seconds.
Replace the x with 2: f(2)=2*2+7=4+7=11
replace the x with 7: f(7)=2*7+7=14+7=21
