Correct option is D) -0.6.
<u>Step-by-step explanation:</u>
We have
. Also, we know that
. Let's find out value of
using above formula:

⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
But we know that cos
is negative in third quadrant , Therefore
.
Hence, correct option is D) -0.6.
the local maximum is at x = -2.2 and has a value of 72.576
The resulting equation if Becca isolated x² in the first equation and then substituted it into the second equation is (9-y²) / 25 - y²/36 = 1
<h3>Equation</h3>
x² + y² = 9
x²/25 - y²/36 = 1
From (1)
x² = 9 - y²
substitute x² = 9 - y² into (2)
x²/25 - y²/36 = 1
(9-y²) / 25 - y²/36 = 1
Therefore, the resulting equation is option C; (9-y²) / 25 - y²/36 = 1
