It can be anyways..400 minutes after 30 or 30 minutes after 400
I pretty sure the best answer would be f(x)=cbrt(27-x)
cbrt means cube root by the way.
Answer:
(7x-1)(x-3)
Step-by-step explanation:
7x^2 - 22x + 3
The factors have to add to -22, but multiply to equal 3. But since the "a" value has a number on it, you have to use it too.
(7x +/- [n1]) ( x +/- [n2]) = 7x^2 - 22x + 3
Since the two numbers multiply to a positive value, they have to have the same sign. (7x-1) (x-3) works to produce the expression when it's foiled.
Answer:
The records can be select in 332,640 ways.
Step-by-step explanation:
Consider the provided information.
There are 11 records to select from and a disc jokey can play 6 records.
Here, we need to find the number of permutation of n = 11 records taken r = 6 at a time.
Use the formula: 
Substitute the respective values in the above formula.




Hence, the records can be select in 332,640 ways.
The answer for part a would be 130
the answer for part b would be 60
