D) The big Bang theory. This focuses on the origin of the earth.
It takes 2minutes to make one bag.
If Ashley works alone:
900 bags * 2 minutes= 1800 minutes
Since there is 60 minutes in a hour:
1800/60=30 hours
There is 6 people doing it so:
30 hours/6 people=5 hours
The final answer is 5 hours.
Hope this helps!
Step-by-step explanation:
m=y2-y1/x2-x1
m=-9+5/-10+8
m=2
Let the equation be:
y = ax^2 + bx + c.
Then, substitue the three points into the equation.
First point: 0 = a0^2 + b0 + c.
So c = 0.
Second point: -2 = a(-1)^2 + b(-1) + c.
So a - b + c = -2.
Third point: 6 = a*1^2 + b*1 + c.
So a + b + c = 6.
We know that c=0 already, so we substitute c=0 into the last two equations and we would get:
a - b = -2
a + b = 6
We add the two equations and we get:
2a = 4
a = 2
Then, we substitute a=2 into a-b=-2 and we get:
-b = -4
b = 4
Now we know a = 2, b = 4, and c = 0
Then, the equation of the parabola would be:
2x^2 + 4x
