Answer:

Since the ray bd is bisecting the angle abc, equate 3x + 4 to 7x - 20.

Step-by-step explanation:

3x + 4 = 7x - 20

x = 6

.. Therefore, angle abc = 3x + 4 + 7x - 20

= 18 + 4 + 42 - 20

= 44

Answer:

(y - i\sqrt{7})(y + i\sqrt{7})

Step-by-step explanation:

Factor as a difference of squares, that is

y² + 7

= y² - (i\sqrt{7} )²

= (y - i\sqrt{7})(y + i\sqrt{7})

1. Find the equation of a normal to the curve y= 2² - 2x +3 at the point (3,0)​
Gala2k [10]

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
