The equation

<span>defines a hyperbolic cylinder.
</span>
1. Divide the equation

by 900:

.
This is the equation of conic section when z=0 (or z=const) and that is hyperbola equation.
2. To find the domain and the range you should express y:

.
Since you have square root,

. This is the domain, the range is

.
Answer:
<h2> B and C are not independent events </h2>
Step-by-step explanation:
This is a probability question, basically on independent events.
B and C are said to be independent if the occurrence of either event does not affect the occurrence of the other.
And now considering the fact that C will always present a head any way anyhow, the occurrence
of C will affect the outcome of B and C.
<em>Hence B and C are not independent events</em>
Answer:
180°
Step-by-step explanation:
∠LMN = 90° and is the angle in a semicircle, thus
LN is the diameter of the circle and the measure of arc LPN is
m arc LPN = 180°
Answer:
it hsould be
