How many different 4-digit numbers can be formed from the following numbers, 3, 7, 2, and 5, using each digit only once?

You have four digits to place: __ __ __ __

In the first position, you have 4 choices of numbers.

Once the first digit is placed, you have 3 choices left for the second position.

Once the second digit is placed, you have 2 choices left for the third position.

Once the third digit is placed, you have only 1 choice left for the last position.

This gives you 4x3x2x1 = 24 possibilities.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
