Question

help please i give metals

Answer 1

The first problem is an exponential function

Answer 2

what does that mean

Answer 3

\[9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1=?\]

Answer 4

ok so its 362,880? can you help me with number two?:)

Answer 5

Correct and I am not sure at what the P in the exponent means?

Answer 6

me either. can you help me with my other ones?

Answer 7

For problem 3 it would be the exponential amount of letters in the word "equation" since there are no repeating letters so it would be?

Answer 8

Alright the P in the exponent symbolizes permutations and since the order matters then we have \[25!^P3 = 25!/22!\]

Answer 9

That is for problem 2

Answer 10

Problem 4, it does not matter the order of how the photographer can arrange the 5 friends so we have another exponential function of the amount of things we are arranging and in this case the friends so it would be:
\[5!= ?\]

Answer 11

The last problem shows that we have 1 bike lock with 5 numbers on it and the counting principle would say that 1 bike lock and 120 ways of arrange the numbers 1x 120 = 120 or 1 bike lock and 5 numbers would be 1 x 5 = 5 which do not fit any of the multiple choice questions except for "none of the above"
