We can solve this problem using discriminant.
x^2-4x-12's discriminant is
(-4)^2-4*-12=16+48 which is clearly larger than 0
This means that it crosses over the axes 2 times.
In case you don't know what discriminant is, its in equation ax^2+bx+c
the discriminant is b^2-4ac.
If its positive it has 2 crosses with x axis, if negative then 0 crosses, if 0 then 1 cross.
Hope this helped at least a little bit :D
Answer:
The other side is 7.48 yards.
Step-by-step explanation:
Given that,
Hypotenuse = 15 yards
One leg = 13 yards
We need to find the length of the other leg. We can use the Pythagoras theorem to find it such that,
Where
h is other leg
Put all the values,
So, the other side is 7.48 yards.
General Form is the most basic form of an equation and is used as a template to form equations designed to solve a specific problem.
The equation given is "<span>(x- -1)^2 +(y-1)^2 =225.0".
The general form of this Equation would be presented as
