Question 1138308: Find an equation in standard form for the hyperbola with vertices at (0, ±4) and asymptotes at y = ± 1 divided by 4 x. (5 points)

y squared over 16 minus x squared over 64 = 1

y squared over 16 minus x squared over 256 = 1

y squared over 256 minus x squared over 16 = 1

y squared over 64 minus x squared over 4 = 1

Find an equation in standard form for the hyperbola with vertices at (0, ±4)
and asymptotes at +y = ± %281%2F4%29+x

standard form:
since the vertices are at (0, ±4), that means the parabola opens up and down, and a+=+4 (the distance from center to vertex)
the center will be halfway between the vertices at:(h, k) = (0, 0)
the hyperbola will look like:
%28y-k%29%5E2+%2F+a%5E2+-+%28x-h%29%5E2+%2F+b%5E2+=+1++++
%28y-0%29%5E2+%2F+4%5E2+-+%28x-0%29%5E2+%2F+b%5E2+=+1++++
y%5E2+%2F+16+-+x%5E2+%2F+b%5E2+=+1++++
since given asymptotes at y = ± %281%2F4%29+x+, the slope of the vertices will be ± a%2Fb, and we have
± 1%2F4 = ±+4%2Fb+=> b+=+16
substituting in b+=+16 :
y%5E2+%2F+16+-+x%5E2+%2F+16%5E2+=+1++++
y%5E2+%2F+16+-+x%5E2+%2F+256=+1+
