Stella initially put $5 into a piggy bank. over the next few years she continued to put all of her coins in the piggy bank, such that each year the amount of money in the piggy bank doubled. determine the equation that represents this situation and use it to decide which of the following graphs represents the amount of money, a(x), in stella's piggy bank after x years.

Step-by-step explanation:

The given scenario can be represented by an exponential growth function. The general form if the exponential growth function is,

where,

y = the future amount after time x,

a = initial amount,

r = rate of growth.

As here A(x) represents the amount of money after x years with initial deposit of  $5 and in each year the amount doubles or duplicates itself i.e r=100% = 1, so the function would be,

At the beginning the amount was $5, so the y intercept of the graph will be at 5.

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.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
