C like circumference:
C = 2 π * r = 2 * 3,14 * 3,5 = 21,99 ≈ 22 m

A like area:
A = π r² = 3,14 * (3,5)² = 3,14 * 12,25 = 38,48 m

Find the critical numbers of the function. (Enter your answers as a comma-separated list. Use n to denote any arbitrary integer

lyudmila [28]

$f(\theta)=10\cos\theta+5\sin^2\theta$

then the derivative is

$f'(\theta)=-10\sin\theta+10\sin\theta\cos\theta$

Critical points occur where $f'(\theta)=0$ . This happens for

$-10\sin\theta+10\sin\theta\cos\theta=0$

$-10\sin\theta(1-\cos\theta)=0$

$\implies-10\sin\theta=0\text{ or }1-\cos\theta=0$

In the first case, we find

$-10\sin\theta=0\implies\sin\theta=0\implies\theta=n\pi$

In the second,

$1-\cos\theta=0\implies\cos\theta=1\implies\theta=2n\pi$

So all the critical points occur at multiples of $\pi$ , or $n\pi$ . (This includes all the even multiples of $\pi$ .)

Write the equation in slope intercept form

notsponge [240]

Hello: 
 an equation is : y =ax+b ( a is a slope )

parallel to the line (q) : y=6/5x-1 a =6/5 ( same slope )
the equation of (r) : is : y = 6/5x+b

the line through point (5,5) : 5= (6/5)(5)+b ...b=-1

an equation of (r) : is : y = 6/5x-1

or : 6/5x-y = 1
