You are right.

I don't know.

Here is a math Q.  What is the fomula of a proabola at the origin?


maartenotten
Depents on the type of parabola but a standard one like y=x^2 in the origin the formula is y=0
Grayhound

Here's a good one

Every day a man saw his dog ran into the woods. However, he noticed that the dog never ran more than halfway into the woods. Why?


maartenotten
Answer: When the dog would run more than halfway he would run out of the woods instead of into the woods.

Yes but you forgot a. y=ax^2

what about the vertex is at (h,k)?

Then its just y`= 2ax (differential equotation)

Then it is not a quadratic equation. It NEEDS to be y=ax^2

Although this isn't a Q but what math calsses didu guys take i'm going in pre-calc

RyanMK

y= a(x-h)^2+k

Chessdude133

100% triangles just have to have three sides it doenst matter the length

What's wrong with this proof?

Let : a = b

Multiply by a : a^2 = ab

Subtract b^2 : a^2 - b^2 = ab - b^2

Factor : (a+b)(a-b) = b(a-b)

Divide by the common factor (a-b) : a+b = b

Substitute from line #1 : b+b = b

Group like terms : 2b = b

Divide by b : 2 = 1

What went wrong?

 

Benedict610

when you divide by the common factor a-b, since a=b, then its a-a which = 0, and you cant divide by zero
