Answer:
Have you tried the quadratic formula? you can look up the quadratic equation and plug in the, a=1 b=2 and c=10
Step-by-step explanation:
We'll first clear a few points.
1. A hyperbola with horizontal axis and centred on origin (i.e. foci are centred on the x-axis) has equation
x^2/a^2-y^2/b^2=1
(check: when y=0, x=+/- a, the vertices)
The corresponding hyperbola with vertical axis centred on origin has equation
y^2/a^2-x^2/b^2=1
(check: when x=0, y=+/- a, the vertices).
The co-vertex is the distance b in the above formula, such that
the distance of the foci from the origin, c satisfies c^2=a^2+b^2.
The rectangle with width a and height b has diagonals which are the asymptotes of the hyperbola.
We're given vertex = +/- 3, and covertex=+/- 5.
And since vertices are situated at (3,0), and (-3,0), they are along the x-axis.
So the equation must start with
x^2/3^2.
It will be good practice for you to sketch all four hyperbolas given in the choices to fully understand the basics of a hyperbola.
Answer:
Their weekly sales would have to be $10,000 before they can be earning the same amount for the week
Step-by-step explanation:
If they are to be earning the same thing each week, it means whatever Toni is earning is what Nicky would be earning.
We proceed by equating their earnings so we would get x;
800 + 0.07x = 600 + 0.09x
Collect like terms
800-600 = 0.09x -0.07x
200 = 0.02x
x = 200/0.02
x = 10,000
