Answer:
<h2>A) 5</h2>
Step-by-step explanation:
The equation of a circle:

(h, k) - center
r - radius
We have the equation:
<em>divide both sides by 3</em>

You would need a rainbow shape ruler to answer these angles/degrees
I think you meant to say the equation is
y = 2x² - 2x + 3
Differentiate both sides with respect to x :
dy/dx = 4x - 2
At the point (3, 0), the slope of the tangent line is dy/dx(3) = 4•3 - 2 = 10. Then the normal line to the curve at (3, 0) has slope -1/10.
Using the point-slope formula, the equation of the normal line is
y - 0 = -1/10 (x - 3) ⇒ y = (3 - x)/10
