What are the zeros of the function?

Mathematics
1 answer:
Gwar [14]4 years ago
5 0

Answer:

B. -3

C. 0

E. 4​

Step-by-step explanation:

g (x)=x^3-x^2-12x

Set this equal to zero

0=x^3-x^2-12x

Factor out an x

0=x(x^2-x-12)

Factor inside the parentheses.

What two numbers multiply to -12 and add to -1

-4*3 = -12

-4+3 = -1

0=x(x-4)(x+3)

Using the zero product property

x=0  x-4=0  x+3=0

x=0  x=4   x=-3

OLga [1]

234 trees in 6 days so you divide 234 by 6 (39) so she plants 39 each day. Now you divide 351 by 39 (9) so at that rate it'll take 9 days in total and 6 days have already passed. So, 3 more days.

Step-by-step explanation:

f(x) maxmum value is

\frac{ - 4}{ - 4}  = 1

- 2( {1}^{2} ) + 4(1) + 3 =  5

G(x) minimum value is 6.

B is the answer.

A new animal hospital is planning to purchase a total of 36 cages for dogs, cats, and
Assoli18 [71]
For simplicity’s sake:
D = dogs, C = cats, R = rabbits

Since the dogs and the cats are the same number, we can say C = D.

R = 1/4D

2D + 1/4D = 36

Combine like terms and get the same denominator

9/4D = 36

9D = 144

D = 16

Now we know that D is 16, so C must be 16 as well. That leaves us with 32 cages.

36 - 32 = 4 rabbit cages. To double check this, 1/4 of 16 does equal 4.

Final answer: 16 D, 16 C, 4 R
