This is the question: The nth term of a sequence is given by Tn = 10n + 4. Put Tn < 100, and hence show that the nine terms T1 to T9 are less than 100. The answer is: < 9. Hence, there are 9 terms, 1 to 9 that are
less than 100.
But I don't understand, how do you know that from the answer of n, we can say 9 terms are less than 100? Please help me.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
