Answer:
252
Step-by-step explanation:
The order of the books isn't important, so we'll use combinations.
The number of ways to choose 5 books from 10 is:
₁₀C₅ = 10! / (5! (10 − 5)!)
₁₀C₅ = 10! / (5! 5!)
₁₀C₅ = 10×9×8×7×6 / (5×4×3×2×1)
₁₀C₅ = 252
Answer:
h(n) = h(n - 1) + 12
Step-by-step explanation:
Generate the first few terms using the explicit formula
h(1) = - 10 + 12 = 2
h(2) = - 10 + 24 = 14
h(3) = - 10 + 36 = 26
h(4) = - 10 + 48 = 38
This is an arithmetic sequence. To find a term in the sequence add 12 to the previous term, thus
h(n) = h(n - 1) + 12 with h(1) = 2
24 is the answer because you have to muiltuple it
