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 $\pi$ .)

Today, everything at a store is on sale. The store offers a 20% discount.

Mila [183]

Answer: $14.40

10% of $18 = $1.80 (just divide it by 10)
$1.80 x 2 = $3.60
20% of $18 = $3.60

since it’s a discount, you subtract from the original price so:

$18 - $3.60 = $14.40

Write the multiplicative inverse of <br>a) -13/19

irga5000 [103]

Answer:

$- \frac{19}{13}$

Step-by-step explanation:

$the \: multiplicative \: inverse \: of \: \\ - \frac{13}{19} = - \frac{19}{13}$

Product of a number and its multiplicative inverse should be equal to 1.

So,

$\bigg ( - \frac{13}{19} \bigg) \bigg ( - \frac{19}{13} \bigg)$

$= \frac{13}{19}\times \frac{19}{13}$

$=1$
