Answer:

After 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

Step-by-step explanation:

Since after a while, Jada picks up a coin that seems different than the others, and she notices that the next day, only half of the coin is left, while on the second day, only 1/4 of the coin is left and, on the third day, 1/8 of the coin remains, to determine what fraction of the coin remains after 6 days, what fraction of the coin remains after 28 days and determine if the coin will disappear completely, the following calculation must be performed:

1/2 ^ 6 = X

0.015625 = X

1/64 = X

1/2 ^ 28 = X

0.0000000037252902984619140625 = X

1/268435456 = X

Thus, after 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

F(x) = 1 / 2<br> g(x) = x - 4<br> Can you evaluate (g o f) (0)? Explain why or why<br> not.
Vitek1552 [10]

For this case we have the following functions:

f (x) = \frac {1} {2}\\g (x) = x-4

We must find (g_ {o} f) (x). For definition of composition of functions we have to:

(g_ {o} f) (x) = g (f (x))

So:

g (f (x)) = \frac {1} {2} -4 = \frac {1-8} {4} = \frac {-7} {4} = - \frac {7} {4}

Then, for any value of "x", the composite function has a value of- \frac {7} {4}.

Thus,(g_ {o} f) (0)cannot be evaluated, it will always be obtained - \frac {7} {4}.

ANswer:

For any value of "x", the composite function has a value of- \frac {7} {4}.
