Answer:
f(x) = x(x +4)(x -3)
Step-by-step explanation:
Zeros at -4, 0, and 3 tell you the factorization is ...
f(x) = a(x +4)(x)(x -3)
Then f(2) = a(6)(2)(-1) = -12a.
The graph shows f(2) = -12, so a=1. That makes the function rule:
f(x) = x(x +4)(x -3)
__
If you want it multiplied out, it will be
f(x) = x^3 +x^2 -12x
Answer:
1/36 ≈ 0.028
Step-by-step explanation:
In order to get a total of 2 if you roll 2 dice, you have to roll two ones. (You can't roll a 0 and 2 because an average die does not have a zero on it)
You have a 1/6 chance to roll a 1 on the first die; and you have a 1/6 chance to roll a one on the second die.
To find the probability of this happening together you have to multiply them together.
1/6 * 1/6 = 1/36 = 0.0277778 ≈ 0.028
Answer: 13
Step-by-step explanation:
Well actually
13
and a half, but we are assuming he needs full pieces, so
13
shelves.
This is simple division:
Mr. Gengel needs shelves that are
1
1
3
feet long and has an
18
foot long board. In order to determine how many shelves he can make you must divide:
18
÷
1
1
3
=
13.5
You can't have half a shelf so you round down to
1
