In how many ways can 12 basketball players be listed in a program?
a. 12
b. 479,001,600
c. 665,280
d. 1

 B. 479,001,600

Step-by-step explanation:

We know that the number of possible combination objects from a set where order matters is given by using permutations.

Given: The number of basketball players = 12

By using permutations, the number of ways the basketball players can be listed is given by :-

B. 479001600

Step-by-step explanation:

We are asked to find the number of ways can 12 basketball players be listed in a program.

We will use permutations to solve our given problem.

There are 12 ways to choose 1st player for the team.

Since 1 player is already chosen, so we can choose 2nd player in 11 ways. Similarly we can choose 3rd player in 10 ways.

Therefore, in 479001600 ways can be 12 basketball players be listed in a program and option B is the correct choice.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
