The formula κ(x)= f′′(x) 1+f′(x)23/2 expresses the curvature of a twice-differentiable plane curve as a function of x. Use thi

Katyanochek1 [597]

Answer:

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

Step-by-step explanation:

considering the Given function

F(x) = $-5x^2$

first Determine the value of F'(x)

F'(x) = $\frac{d(-5x^2)}{dy}$

F'(x) = -10x

next we Determine the value of F"(x)

F"(x) = $\frac{d(-10x)}{dy}$

F" (x) = -10

To find the curvature function we have to insert the values above into the given formula

K(x) $= \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }$

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

Find m2D. D C A 88° B

Rasek [7]

Answer:

$\huge\boxed{\sf \angle D = 92\°}$

Step-by-step explanation:

<h3><u>Statement:</u></h3>

If a quadrilateral is inscribed in a circle, the opposite angles add up to 180 degrees.

<h3><u>According to the statement:</u></h3>

∠D + 88° = 180°

<em>Subtract </em>88 to both sides

∠D = 180° - 88°

∠D = 92°
