What is 3 root of 384?

1 answer:

5 0

1. The cube root of 384 can be rewritten as the cube root of (8*48). That can be simplified to 2 cube root of 48. That can be simplified down further to 2 cube root of (6*8), which is 2*2 cube root of 6, or 4 cube root of 6. So, the answer is C.

You do the same thing for each of the problems. If you actually want me to just give you the answers, they are:
1. C
2. D
3. D

If x = 3 is a zero of the polynomial function f(x) = 2x3 + x2 − 25x + 12, which of the following is another zero of f(x)?a. x =

Answer:

b) $x=-4$ is another zero of the polynomial

Step-by-step explanation:

Since you are given a set of options to choose from, a very simple way to find the zero of the polynomial is by simply plugging each value from the options and seeing which of them gives the answer 0.

$f(x) = 2x^3+x^2-25x+12\\$

Using all the options:

$a)\,f(-3) = 2(-3)^3+(-3)^2-25(-3)+12\\f(-3) = 42\\\\b)\,f(4) = 2(4)^3+(4)^2-25(4)+12\\f(4) = 56\\\\c)\,f(-4) = 2(-4)^3+(-4)^2-25(-4)+12\\f(-4) = 0\\\\d)\,f(12) = 2(12)^3+(12)^2-25(12)+12\\f(12) = 3312$
