Answer the question below
lys-0071 [83]

Answer:

A) -1

Step-by-step explanation:

\frac{3 + 2\sqrt{5} }{2\sqrt{5}-3 } \\

We can rewrite 2√5 - 3 as -(3 + 2√5)

Therefore,

\frac{3+ 2\sqrt{5} }{-(3 + 2\sqrt{5} )} \\

We can cancel out 3 + 2√5 both in the numerator and the denominator. So we get

= 1/-1

= -1

Answer : A) -1

Thank you.

Find an equation for the line tangent to the circle x^2 +y^2=25 at the point (3, -4)
Lostsunrise [7]
Hello : 
the center of this cercle is : O( 0, 0)
calculate the slope  m of the line : OA    .. A (3,-4)
m= (yA - yO) / (xA- xO) 
m = (-4-0)/(3-0)
m= -4/3
if : k the slope of the tangent : k×m = -1   (the tangent perpendiclar of : OA)
k× (-4/3) = -1
k = 3/4
an equation of this tangent is : y - (-4) = (3/4)(x-3)
