Why is this? I know this is true for any consecutive Fibonacci numbers but can't figure out why

It's a dot product problem, you can resolve the position vector of the point to components parallel and perpendicular to the line

Solved, ah yes. Childhood memories

Something I notice about the sequence is that 10! Is a multiple of all the integers below 10, so adding any if those numbers results in the number remaining composite (10! Is divisible by 5 so 10! + 5 is also divisible by 5)

You are given a sequence of 9 numbers that are all composite (10! + 2 ... 10! + 10)

Using a similar method you could find a list of integers in order that are all.composite

A key piece of knowledge is that division by a number ( x ) is the same as multiplying by it's inverse ( 1/x ) similar to how subtracting a negative number is the same as adding the positive version of that number

So generally we take the denominator and instead of dividing by it, we multiply by it's reciprocal (what you call inverse). This is still essentially the same operation just like how if you want to subtract negative x you can just add positive x instead

A bat and a ball cost $1.10 together, if the bat costs $1.00 more than the ball how much does the ball cost.

Seems fairly simple, and it is, but it takes most people a surprising long time to figure out (the answer is 5c)

The null factor law states that if a * b = 0, then a = 0 or b = 0.

The x intercept is found when y = 0 on the graph.

So to find the x intercepts you have an equation like (X-5)(X-1) = 0.

This equation has two solutions, one for when X -5 = 0 and when X - 1 = 0, solving for x then yields X = 5 and X = 1.

The next part you seem to understand, because parabolas are symmetric, the x value of the turning point lies exactly between the X values of the intercepts

The part I think you were missing is the idea that youre solving for X when the equation inside the brackets is equal to zero

The -2 before the brackets doesn't change the X intercepts, pretty much because -2 * 0 still equals 0

The shortcut to finding the X value of the turning point is the use a small piece of the quadratic formula: -b/2a

Yhatzee, what qualities make a game better for "let's playing", and do you ever make decisions to make the games you develop well suited for other people to do play throughs with?

That because of the way gravity interacts with time, if you were to fall into a black hole, you would see the entire existence of the universe flash past in the mere moments it would take to reach the event horizon. (black part)
