In the expression 9 with a -12 exponent what does the negative exponent mean?

9^(-12)= 9x10^-12

Step-by-step explanation:

The exponent is the number of placements that means

ex.,

if we have any number with another number in the exponent, this indicates the number of multiples or if the number is in a reduced form for the number of placement after or before in zeros;

Example:

for a positive number let say we have the number 10^3

this will equal 10,000.0 there are 3 zeros after the 10

In case of a negative exponent

let say we have

10^-3, then we expand it by moving the placement to the left side of the number, that whould be 0.001

So for the original question we are summose to move the number to the right by adding 12 zeros

9^-12= 9.0^-12= 0.000,000,000,009

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

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.
