Answer:
9.45
Step-by-step explanation:
3.5 x 2.7 = 9.45
Since the circle is centered at the origin, we can use the equations
x² + y² = r²
x = r cos θ
y = r sin θ
We know y = 8 and r = 10. Solving for x
x² + 8² = 10²
x = 6
From this equation:
x = r cos θ
6 = 10 cos θ
cos θ = 6/10 = 0.6
The top question is y=2x+6
the bottom question is y=5/2x-6
