Taking the focus of y212 − x24 = 1 as the vertex, the elliptic equation with the vertex as the focus is______ .

Taking the focus of y212 − x24 = 1 as the vertex, the elliptic equation with the vertex as the focus is______ .

∵ the focus of hyperbola y212 − x24 = 1 is (0,4), (0, - 4) vertex is (0,23) (0, - 23) ∵ the focus of ellipse with hyperbola as vertex and vertex as focus is (0,23) (0, - 23) vertex is (0,4), (0, - 4) ∵ the equation of ellipse is y216 + x24 = 1, so the answer is: y216 + x24 = 1
Find the elliptic equation with the vertex of hyperbola y ^ 2 / 3 - x ^ 2 / 5 = 1 as the focus and the vertex of hyperbola as the focus
Vertex coordinates of hyperbola (√ 3,0) and (√ 3,0)
c²=3+5=8,c=2√2
So the half focal length of ellipse C '= √ 3, vertex a' = 2 √ 2
b' ²=a' ²-c' ²=8-3=5
So the elliptic equation x & # 178 / 8 + Y & # 178 / 5 = 1
Given that the solution of the equation 3x + a = 0 is 2 larger than that of the equation 5x + 2A = 0, what is the value of a?

A=4
The square root of a is 2 or - 2
If the quadratic equation KX & # 178; - 6x + 9 = 0 with respect to X has two unequal real roots, then the value range of K is?
It can be seen from the meaning of the title: B & # 178; - 4ac = 36-36k > 0, K < 1
Given that 5 is the solution of the equation 3x-2a = 7 about X, then the value of a is___ .
∵ x = 5 is the solution of the equation 3x-2a = 7 about X, ∵ 3 × 5-2a = 7, the solution is a = 4
How many integers are greater than √ 17 and less than √ 37
4=√16
5=√25
6=√36
7=√49
So there are five and six
√17=4.1
√37=6.08
There are 5 and 6 integers greater than √ 17 and less than √ 37
There are 5 and 6 in total
Two, five and six
If the quadratic equation kx2-6x + 1 = 0 with respect to X has two unequal real roots, then the value range of K is___ .
∵ kx2-6x + 1 = 0 has two unequal real roots, ∵ △ = 36-4k > 0, and K ≠ 0, the solution is k < 9 and K ≠ 0, so the answer is k < 9 and K ≠ 0
If the solution of equation 3x + 2A = 12 is the same as that of equation 3x-4 = 2, find the value of A
3x-4 = 2x = 2, ∵ equation 3x + 2A = 12 has the same solution as equation 3x-4 = 2. Substituting x = 2 into 3x + 2A = 12, we get 6 + 2A = 12, a = 3
