Answer:
Step-by-step explanation:
A hyperbola is the locus of a point such that its distance from a point to two points (known as foci) is a positive constant.
The standard equation of a hyperbola centered at the origin with transverse on the x axis is given as:
The coordinates of the foci is at (±c, 0), where c² = a² + b²
Given that a hyperbola centered at the origin with x-intercepts +/- 4 and foci of +/-2√5. Since the x intercept is ±4, this means that at y = 0, x = 4. Substituting in the standard equation:
The foci c is at +/-2√5, using c² = a² + b²:
Substituting the value of a and b to get the equation of the hyperbola:
So now it is an division problem, I got out my calcuator for this.
The numarical eqpression is 212212 / 5. It said 42442.4. It is in simpelest form!
I would be thankful for brainliest!
The answer to 21 is a translation
The coordinates to 22 is A'(2,5), B'(2,3), C'(5,3)
Answer:x=0,5
Step-by-step explanation:
6x -1/2=1
6x-1=1.2
6x-1=2
6x=2+1
6x=3
x=3/6
x=0,5
