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:
Answer:
C) 3.25
Step-by-step explanation:
Just do 81.25 divided by 25 to get 3.25
a=1/3 so 7a becomes 7x1/3
2 1/3-3= -2/3
hope it helps!
Answer:
−0.608761429
Step-by-step explanation:
use the pathagreom theorem if you have two sides subtract that from 180
Answer:
(t - 2)(t + 2)(t² + 4)
Step-by-step explanation:
Difference of Squares: a² - b² = (a - b)(a + b)
Step 1: Write expression
t⁴ - 16
Step 2: Difference of Squares
(t² - 4)(t² + 4)
Step 3: Difference of Squares
(t - 2)(t + 2)(t² + 4)
