Find the value of given trigonometric function cot (-330°)

Answers

Answer 1

Answer:

The exact value should be

[tex] \sqrt{3} [/tex]

Step-by-step explanation:

Though you can get this directly out from your calculator, but you can utilize the opposite angle identities, cot(-

θ)=-cot θ, then use the trig identity, which is

[tex] \cot(θ) = \frac{ \cos(θ) }{ \sin(θ) } [/tex]

So cot (-330)=cos (-330)/sin (-330)

The length of a rectangle is 9” greater than the width. The area is 36”2. Find the dimensions

Answers

Answer:

Step-by-step explanation:

L = W+9

area = LW = 36

(W+9)W = 36

W²+9W-36 = 0

W = -12, 3

-12 is an extraneous solution, so W = 3 inches

L = W+9 = 12 inches

Choose 3 values that would make this inequality true. 7n ≤ 21

Answers

Answer:

A couple could be 2, 1, or even a decimal 1.3 as an example.

Step-by-step explanation:

Divide both sides by 7:

7n/7 < 21/7

n < 3

Any value of n less than 3 will make the inequality true, so just pick three values (numbers) for n that are less than 3, such as n = 2.

a train travels 16 miles in 20 minutes how many minutes would 12 miles be

Answers

Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.

Step-by-step explanation:

16 miles     =  12 miles

20 mins.        how many mins?

16    =   12       cross multiply       16? = 240   divide by 16     240 divided by 16 = 15 miles

20          ?                                                                                because 15 x 16 = 240

Answer:

It will take 15 minutes to travel 12 miles.
