First distribute the negative to the second equation which would give you:
25x^2 - 14xy + 4 -7x^2 + 9y + 2xy + 7
Since addition is commutative. you can now just add like terms.
18x^2 - 12xy + 9y + 11
I assume you are looking for arc RSQ, since you already now the angle RSQ.
Arc RSQ is 312 degrees.
Since you know angle RSQ, the arc that it creates is twice the angle.
24 x 2 = 48
Arc RSQ is the entire circle (360 degrees) except for that 48 degrees.
360 - 48 = 312
Answer:
18 miles
Step-by-step explanation:
Let's call it's initial elevation x. Because it descends 3 miles, we now have x - 3. The question says it is now 15 miles above sea level, or x - 3 = 15, and adding 3 to both sides shows that x = 18 miles.
The answer I got was 912.3 Your welcomeee c:
