Find the critical numbers of the function. (Enter your answers as a comma-separated list. Use n to denote any arbitrary integer
lyudmila [28]

If

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.)

A train leaves at 14:56 and arrives at 16:43. It travelled at an average speed of 135 km/h. How far did it travel? Give your ans
Firlakuza [10]

Answer:

240.8

Step-by-step explanation:

→ Calculate time taken

16:43 - 14:56 = 1 hour and 47 minutes

→ Write the speed formula and make distance the subject

Speed = Distance ÷ Time ⇔ Distance = Speed × Time

→ Convert 1 hour and 47 minutes into decimal format

1.78333333 or  1\frac{47}{60}

→ Substitute values into formula

135 ×  1\frac{47}{60}  = 240.75

Sixty percent of what number is equal to 45 percent of 80?
Dovator [93]

Answer:

60

Step-by-step explanation:

60% * x = 45% * 80

Changing to decimal form

.60x = .45 *80

.60x =36

Divide each side by .60

.60x/.60 = 36/.60

x =60

Jeremiah always rides his bike to and from work the total length of the trip to and from work is 14.6 kilometers last month Jere
dezoksy [38]

Answer:

As per the given statement: Jeremiah always rides his bike to and from work the total length of the trip to and from work is 14.6 kilometers last month.

⇒\text{Total length of the trip to and fro from work last month} = 14.6 km

Also, it is given that Jeremiah worked 18 days.

then;

\text{Total distance he ride his bike} = 14.6 \times 18 = \frac{146}{10} \times 18 = \frac{146 \times 18}{10} = \frac{2628}{10}

Simplify:

\text{Total distance he ride his bike} = 262.8 km

Therefore, 262.8 km did he rode his bike to and from work last month
