A hyperbola has its foci at (7,5) and (7-5). A directrix of the hyperbola is y = 16/5
What is the equation of the hyperbola?

y^2/16 - (x-7)^2/9 = 1

Step-by-step explanation:

Just took le test

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
