<span>-1<0
so use 2x+1
2(-1)+1=-2+1=-1
-
</span><span>F(-1) means "Evaluate F(x) when x=-1"
Since -1 is less than 0, this means that F(x) = 2x+1. This is because F(x) = 2x+1 when x < 0</span>
1: x² + 10x + 25
2: x² - x -12
3: -2x² + 10x
4: -2x² + 9x + 5
5: n² - 4
---------------------------
1: x² + 14x + 49
2: x² - 14x + 49
3: 4n² - 20n + 25
4: 4n² + 20n +25
5: you just have to switch the signs
Answer:
Correct option: C (it is missing the point)
0.53
Step-by-step explanation:
When a ball rolls one revolution, the distance travelled is the length of its circunference, that is:
Circunference = pi * diameter
So, to solve this question, we can use a rule of three:
1 revolution -> pi * d
60 revolutions -> 100 feet
100 = 60 * pi * d
d = 100 / (60 * pi) = 0.53 feet
Correct option: C (it is missing the point).

Answer:
hello your question is incomplete below is the missing parts of the question
answer : K = 80
Step-by-step explanation:
P [ x ≤ 1 ] < 0.1
determine how large k have to be
note : n = k
sample proportion = 0.01
E = 0.05 - 0.01 = 0.04
applying this formula below
E = 
0.04 = 1.645 
make n subject of the equation
n = 80.3353
hence the value of K ≈ 80
