What is the equation of a hyperbola with a = 5 and c = 15? Assume that the transverse axis is horizontal.

gogolik [260]

Answer:

$\frac{x^2}{25} -\frac{y^2}{200} =1$

Step-by-step explanation:

Recall that the equation of hyperbola centered at the origin with transverse horizontal axis has the general form:

$\frac{x^2}{a^2} -\frac{y^2}{b^2} =1\\and\,\,\,\, with\\c=\sqrt{a^2+b^2}$

since we know that a = 5 ,and c = 15,we can solve for b:

$15=\sqrt{5^2+b^2} \\15^2=25+b^2\\b^2=200\\$

then the equation of the hyperbola becomes:

$\frac{x^2}{5^2} -\frac{y^2}{200} =1\\\frac{x^2}{25} -\frac{y^2}{200} =1$

charle [14.2K]

<span>In order to find the area of a rectangle, the width must be multiplied by the length. Since we know the length is 7 yards and the width is 4 yards, we can simply multiply these two values together. 4yd x 7yd= 28yds^2.</span>
