The curve y = |x|/(sqrt(5- x^2)) is called a bullet-nose curve. Find an equation of the tangent line to this curve at the point
iren [92.7K]
Absolute value
at x=2, the absolute value thing is positive
do this one
y=x \sqrt{5-x^2}
the derivitive is
\frac{dy}{dx}=\sqrt{5-x^2}- \frac{x^2}{ \sqrt{5-x^2} }
so the slope at x=2 is
\frac{dy}{dx}=\sqrt{5-2^2}- \frac{2^2}{ \sqrt{5-2^2} }=-3

a point is (2,2)
point slope form
y-y1=m(x-x1)
y-2=-3(x-2)
or
y=-3x+8

Find the values of which satisfy the equation. 2 cos (2B+30°) = -√3 in the domain OP ≤B≤360°​
PSYCHO15rus [73]

Answer:

60 and 90

Step-by-step explanation:

2 \cos(2 \beta  + 30)  =  -  \sqrt{3}

\cos(2 \beta  + 30)  =  -  \frac{ \sqrt{3} }{2}

2 \beta  + 30 =  \cos {}^{ - 1} ( \frac{   -   \sqrt{3} }{2} )

First solution.

2 \beta  + 30 = 150

2 \beta  = 120

\beta  = 60

Second solution

2 \beta  + 30 = 210

2 \beta  = 180

\beta  = 90
