Answer:
D
Step-by-step explanation:
the hypotenuse is ALWAYS the longest side in a right triangle
X^2 + 4y^2 - 6x = 7
x^2 - 6x + 9 + 4y^2 = 16
(x-3)^2/16 + y^2/4 = 1
The graph is an ellipse

<h2>587</h2>
Step-by-step explanation:
A lead cube of side
is used to make spherical pellets of diameter
.
As the volume of lead is conserved, the volume of raw material equals the volume of finished products.

Let us assume that
cubes are produced. Volume of a cube of side
is
. The volume of a sphere of diameter
is
.

n is rounded off to 587.
∴ 587 spherical pellets can be made.
