the ratio of females to total students in a math class is 18 to 30 what fraction and percent of the class is female
Maksim231197 [3]
Add up 18 and 30.  You'll get 48.  Then 18/48 of the class is female.  Of course this could be simplified:  18/48 = 3/8.  Then 3/8 of the class is female and 5/8 is male.

What are the zeros of the polynomial function f(x) = x3 − 2x2 − 24x?
Morgarella [4.7K]

Answer:

x = 0, x = -4, and x = 6

Step-by-step explanation:

To find the zeros of this polynomial, we can begin by factoring out a common factor of each term. 'x' is a common factor. We can distribute this variable out, giving us:

f(x) = x(x²- 2x- 24)

Now, factor the polynomial inside of the parenthesis into its simplest form. Factors of -24 that add up to -2 are -4 and 6.

f(x) = x( x + 4) (x - 6)

From this, we can derive the zeros x = 0, x = -4 and x = 6.
