center: (1, 4)
a = 2c
foci: (- 3, 4), (5, 4)

Question

amistre64 · Answer

its major axis is the x axis....

i hate to assume that a and c are standard terms when dealing with these;  but i usually see a as the length from the center to the outer vertex

amistre64 · Answer

and c as the measure from the center to a focus

amistre64 · Answer

c = 4; so a=8 in that case and b = sqrt(a^2 -c^2)

amistre64 · Answer

b=sqrt(48); so there should be a 48 tucked under the y part; whats your options?

amistre64 · Answer

x^2      y^2  <- modify for off center
---- + ---- = 1
 64        48

That works just gotta put the center in for h and k... I was close based it off of the last one we did just had them flipped
