Alright, this one is a little interesting... Let's perform some tests to figure out what is happening:
f(-10) = -(1/(-10)^3) = -(1/-1000) = 1/1000 (positive)
f(-5) = -(1/(-5)^3) = -(1/-125) = 1/125 (positive, bigger than the last one)
f(-1) = -(1/(-1)^3) = -(1/-1) = 1 (positive, bigger than the last one)
f(-0.1) = -(1/(-0.1)^3) = -(1/-0.001) = 1/0.001 = 1000 (positive, bigger than the last one)
f(0) = -(1/0^3) = undefined!
f(0.1) = -(1/(0.1)^3) = -(1/0.001) = -1/0.001 = -1000 (negative)
f(1) = -(1/1^3) = -(1/1) = -1 (negative, but bigger than last one)
It's a little confusing with the undefined part at x = 0. What I can say is this, it is increasing from -10 up to 0, something weird happens at 0 and it resets, and starts increasing from 0 up to 0.1.
I guess A would be the best answer?
The value of y in the diagram wiuld be four. think about it. it would be four because how many pieces are in a triangle? mmm it is 3 in a triangle so if i add up one i would have to add 3+1=4 and that is how i got the answer
THANKS TO ME U NOW KNOW THE ANSWER :)
Answer:
1/81
Step-by-step explanation:
Remember:
b^-n = 1/b^n
Then
[(3^2)]^-2 = 1/[9^2]
1/81
Best regards
Y - y1 = m(x - x1) is the point slope equation.
y - 9 = 3(x - -2)
(9, -2)
Letter B
Answer:
Step-by-step explanation:
To find the probablility, add all of the possibilities. Then, divide the outcome by the total possibilities.
x+3x+5x+4x=13x
x/13x=1/13.
So, the probabilit is 1/13.
