Answer:

The number of sides is 7

Step-by-step explanation:

Once the sum of interior angles is equal to 900º and the sum of interior angles is given by

S=(n-2) \cdot 180\º, \text{ as }n \text{ being the number of sides}

900\º = (n-2) \cdot 180\º

\dfrac{900\º}{180\º}  = (n-2)

5 = (n-2)

5+2 = n-2+2

\boxed{n=7}

Answer:

acute angle

Step-by-step explanation:

<h2><em><u>Finding the angle </u></em></h2>

an obtuse angle is an angle which is more than 90° but less than 180°

a right angle is 90°

a straight angle is 180°

an acute angle is less than 90°

is you look at the picture and the definitions you can notice that the angle is less than 90 ° hence its an <u>acute angle </u>

Finding Derivatives Implicity In Exercise, find dy/dx implicity.<br> 4x3 + ln y2 + 2y = 2x
lisov135 [29]

Answer:

\frac{dy}{dx}=\frac{y(1-6x^2)}{(1+y)}

Step-by-step explanation:

Given function : 4x³ + ln(y²) + 2y = 2x

on differentiating both sides with respect to 'x', we get

\frac{d(4x^3 + ln(y^2) + 2y)}{dx}= \frac{d(2x)}{dx}

or

12x^2+\frac{2}{y}(\frac{dy}{dx})+2(\frac{dy}{dx})=2

or

12x^2+(\frac{2}{y}+2)\frac{dy}{dx}=2

or

(\frac{2+2y}{y})\frac{dy}{dx}=2-12x^2

or

\frac{dy}{dx}=\frac{y(2-12x^2)}{2+2y}

or

\frac{dy}{dx}=\frac{2y(1-6x^2)}{2(1+y)}

or

\frac{dy}{dx}=\frac{y(1-6x^2)}{(1+y)}
