Q. What are the foci of the hyperbola represented by the equation 41y2−25x2=1?Choose 1 answer:(A) (4,0) and (−4,0)(B) (66,0) and (−66,0)(C) (0,66) and (0,−66)(D) (0,4) and (0,−4)
Hyperbola Equation Form: The given equation is in the form of a hyperbola with the equation a2y2−b2x2=1, where a2 is under the y2 term and b2 is under the x2 term. This indicates that the hyperbola opens up and down along the y-axis.
Finding the Foci: To find the foci of the hyperbola, we need to use the formula c2=a2+b2, where c is the distance from the center to each focus.
Calculating c^2: From the given equation, we can see that a2=41 and b2=25. Now we will calculate c2.
Substituting Values: Substitute the values of a2 and b2 into the formula to find c2: c2=41+25.
Calculating c: Calculate c2: c2=66.
Locating the Foci: Now, find the value of c by taking the square root of c2: c=66.
Finding the Coordinates: Since the hyperbola opens up and down, the foci are located at (0,±c) along the y-axis.
Finding the Coordinates: Since the hyperbola opens up and down, the foci are located at (0,±c) along the y-axis.Substitute the value of c to find the coordinates of the foci: (0,66) and (0,−66).
