Answer:
D = K-10
Step-by-step explanation:
Let the number of games won by Dave's favourite basketball team be D and Kimiko's be K.
D + 10 = K
therefore,
D = K-10

Consider we need to find f(n).
Given:
Achilles ordered a pizza with 16 slices.
Every hour, he ate half of the remaining slices.
To find:
The function f(n) that is the number of slices Achilles ate in the hour since he got home.
Solution:
Initial number of slices = 16
Every hour, he ate half of the remaining slices. So, the number slices Achilles ate in the hour since he got home are:
8, 4, 2, 1, ...
It is a geometric sequence with first term 8 and common ratio
.
The explicit formula for a geometric sequence is:

Where, a is the first term and r is the common ratio.
Substituting
, we get

Therefore, the function f(n) that is the number of slices Achilles ate in the hour since he got home is
.
Answer:
Step-by-step explanation:
The terms are the addends in the sum:
