Answer:
That actually depends. We don't know if i is a negative number or not. If i is a negative number, -i would be larger. If i is a positive number, -i would be smaller. It all depends on whether i or -i is negative or positive.
Hope that helps!

Answer:
I think you have a mistake in the way you explain there.
P(X=4) = 0.8*0.8*0.8*0.2 = 0.1024
But don't forget that there is still P(X=5), P(X=6), P(X=7), ... . It's just that our main character here (Hugo) can only buy 4, but it's still a probability that he finally get his fav player card on the tenth try right? And all of that P(X=x) , with x is a positive real number, will sum up to 1. Lets ask Sal to further explain this in another video. SO we know that :
P(X=1) + P(X=2) + P(X=3) + ... = 1
The question is P(X>=2), so you will add P(X=2) + P(X=3) + P(X=3) + ... . By using the equation of the sum of all possibilities, we can get :
P(X=1) + P(X=2) + P(X=3) + ... = 1
P(X=2) + P(X=3) + ... = 1 - P(X=1)

Answer:
266634.11 m^2
Step-by-step explanation:
The following information is given in the question
The ratio of the side of the triangular fields is 6:9:10
And, the perimeter is 2500m
We need to find the area of that field
So
Let us assume the 3 sides be x
Here so the sides be 6x,9x, 10x
Now the perimeter = sum of the length of all sides
2500 = 6x + 9x + 10x
2500 = 25x
x = 100
The three sides would be 600,900 and 1000
Now the area of that field would be
As we know that
The Area of the triangle as per the Heron Formula is
= 266634.11 m^2
5x^2-y=12
y=5x^2-12
dy/dx=10x
d2y/dx2=10
Since acceleration is constant, which is true of all quadratics, and it is positive, there is an absolute minimum for y(x) when dy/dx=0. So it increases without bound on either side of the vertex, meaning that it opens upwards.
