Answer:
(-5, 0) and (5, 0)
Step-by-step explanation:
This equation fits the form for a hyperbola with x-intercepts. The standard form for such an equation is

To get the equation in the question into this standard form, divide each term by 400.

To find the x-intercepts, make <em>y</em> = 0.

The vertices are located at the points (-5, 0) and (5, 0).
<em>Note: </em>There are no <em>y</em>-intercepts; making <em>x</em> = 0 produces no real solutions for <em>y</em>.

Answer:
This will be s - r.
Step-by-step explanation:
Here,
SinB = r
CosB = s
SinB = AC/BC
Also,
CosC = AC/ BC
So, we can say SinB = CosC = r
Again,
CosB = AB/ BC
Also,
SinC = AB/ BC
So,
CosB= SinC = s
So,
SinC - CosC = s - r
